The isolation and partial characterization of the serum lipoproteins and apolipoproteins of the rainbow trout. (1/747)

1. VLD (very-low-density), LD (low-density) and HD (high-density) lipoproteins were isolated from the serum of trout (Salmo gairdneri Richardson). 2. Each lipoprotein class resembled that of the human in immunological reactivity, electrophoretic behaviour and appearance in the electron microscope. Trout LD lipoprotein, however, was of greater density than human LD lipoprotein. 3. The trout lipoproteins have lipid compositions which are similar to those of the corresponding human components, except for their high contents of long-chain unsaturated fatty acids. 4. HD and LD lipoproteins were immunologically non-identical, whereas LD lipoproteins possessed antigenic determinants in common with VLD lipoproteins. 5. VLD and HD lipoproteins each contained at least seven different apoproteins, whereas LD liprotein was composed largely of a single apoprotein which resembled human apolipoprotein B. 6. At least one, and possibly three, apoprotein of trout HD lipoprotein showed features which resemble human apoprotein A-1.7. The broad similarity between the trout and human lipoprotein systems suggests that both arose from common ancestral genes early in evolutionary history.  (+info)

Estimating the effective number of breeders from heterozygote excess in progeny. (2/747)

The heterozygote-excess method is a recently published method for estimating the effective population size (Ne). It is based on the following principle: When the effective number of breeders (Neb) in a population is small, the allele frequencies will (by chance) be different in males and females, which causes an excess of heterozygotes in the progeny with respect to Hardy-Weinberg equilibrium expectations. We evaluate the accuracy and precision of the heterozygote-excess method using empirical and simulated data sets from polygamous, polygynous, and monogamous mating systems and by using realistic sample sizes of individuals (15-120) and loci (5-30) with varying levels of polymorphism. The method gave nearly unbiased estimates of Neb under all three mating systems. However, the confidence intervals on the point estimates of Neb were sufficiently small (and hence the heterozygote-excess method useful) only in polygamous and polygynous populations that were produced by <10 effective breeders, unless samples included > approximately 60 individuals and 20 multiallelic loci.  (+info)

The hatching gland cells of trout embryos: characterisation of N- and O-linked oligosaccharides. (3/747)

A histochemical, light and electron microscopy study of the hatching gland cells (HGCs) in incubated 50-d-old trout embryos is reported. The distribution of carbohydrate residues in the glycoconjugates of these cells was studied by means of a battery of 13 different lectins conjugated with horseradish peroxidase (PNA, ConA, LCA, WGA, SBA, UEA-I, HPA, DBA) or digoxigenin (DSA, MAA, AAA, SNA, GNA). Identification of N- and O-linked oligosaccharides in HGCs was performed by application of both chemical and enzymatic treatments. Present results suggest that HGCs are seromucous cells which store both high choriolytic enzyme (HCE) and low choriolytic enzyme (LCE), and that their cytoplasmic granules, endoplasmic reticulum and Golgi complex contain additional sialic acid-rich glycoproteins. The negative charge of these glycoproteins might be responsible for the rapid expansion of mucin to form a highly hydrated gel, which would facilite the action of these enzymes in programmed cell death and might play a major role during the morphogenic events.  (+info)

Fish macrophages express a cyclo-oxygenase-2 homologue after activation. (4/747)

In mammals, the increased generation of prostaglandins (PG) during the onset of inflammatory responses and activation of immune cell types has been attributed to the induction of a novel cyclo-oxygenase (COX) isoform, termed COX-2, which is distinct from the well-characterized constitutive activity (COX-1). Goldfish (Carassius auratus) macrophages exposed to bacterial lipopolysaccharide and leucocyte-derived macrophage-activating factor(s) showed a significant increase in the generation of the major COX product, PGE2, within the first 6 h of stimulation. The selective COX-2 inhibitor, NS398, inhibited this elevated generation of PGE, whereas the basal level of this product synthesized by unstimulated macrophages was unaffected by such exposure. PGE generation by goldfish macrophages was similarly inhibited by the glucocorticoid, dexamethasone, and an inhibitor of protein synthesis, cycloheximide, suggesting that this stimulation may be due to an inducible enzyme equivalent to mammalian COX-2. The complete coding sequence of rainbow trout (Oncorhynchus mykiss) COX-2 was obtained by PCR. The gene contains a 61 bp 5'-untranslated region (UTR), a 1821 bp open reading frame and a 771 bp 3'UTR containing multiple copies of an mRNA instability motif (ATTTA). The predicted translation product had high homology to known mammalian and chicken COX-2 (83-84%) and COX-1 (77%) sequences. Reverse-transcriptase PCR with cDNA from control and bacterially challenged fish revealed that trout COX-2 expression was not constitutive but could be induced. Overall, these studies show for the first time that the inducible isoform of COX has a long evolutionary history, probably dating back to the evolution of fish over 500 million years ago.  (+info)

Endocrine control of Na+,K+-ATPase and chloride cell development in brown trout (Salmo trutta): interaction of insulin-like growth factor-I with prolactin and growth hormone. (5/747)

A 2-factorial (3x3) injection experiment was used to investigate the effect and interaction between different hormones on the initial phase of seawater (SW) acclimation in brown trout (Salmo trutta). Each fish was given 4 injections on alternate days in freshwater (FW). Factor 1 was either saline, 2 micrograms ovine prolactin (oPRL)/g, or 2 micrograms ovine growth hormone (oGH)/g. Factor 2 was either 0, 0. 01, or 0.1 mirograms recombinant human insulin-like growth factor-I (rhIGF-I)/g. In each of the 9 treatment groups, half of the fish were subjected to a 48-h SW-challenge test, and the remaining fish were sham-transferred to FW one day after the last injection. Hypo-osmoregulatory performance was increased by GH and impaired by PRL treatment as judged by changes in plasma osmolality, [Na+], [Cl-], total [Mg] and muscle water content (MWC) after SW transfer. IGF-I reduced plasma osmolality after transfer to SW but had no effect on plasma total [Mg] or MWC. The effects of the two factors on plasma osmolality, [Na+], [Cl-], and MWC were additive. In sham-transferred fish, GH and IGF-I, alone and in combination, stimulated Na+,K+-ATPase alpha-subunit mRNA (alpha-mRNA) content in the gill. This was paralleled by an overall increase in gill Na+, K+-ATPase activity in fish treated with 0.01 micrograms IGF-I/g. Simultaneous administration of PRL completely inhibited the increase in gill alpha-mRNA observed in the IGF-I-injected groups. Combination of GH and IGF-I did not further affect the alpha-mRNA level relative to the single hormone-injected groups. There was an overall decrease in Na+,K+-ATPase activity in pyloric caeca and middle intestine by the low dose and both doses of IGF-I respectively. No effect was observed in the posterior intestine. PRL and GH treatments did not affect enzyme activity in any intestinal segment. Both doses of IGF-I increased Na+,K+-ATPase-immunoreactive (NKIR) cell density in gill primary filaments. PRL and GH had no effect on primary filament NKIR cell density. GH and both doses of IGF-I reduced secondary lamellar NKIR cell density, whereas PRL had no effect. The main conclusion is that IGF-I and GH induce an overall redistribution of NKIR cells away from the secondary lamella onto the primary filament of FWacclimated trout. This is associated with an overall increased alpha-mRNA level in the gill, which may reflect an increased expression within individual NKIR cells in the primary filament. PRL completely abolished the IGF-I stimulation of alpha-mRNA levels, suggesting a desensitisation of the gill tissue to IGF-I, which may explain the overall anti-SW adaptive effect of PRL.  (+info)

Na(+)-K(+) pump and metabolic activities of trout erythrocytes during anoxia. (6/747)

Metabolic activity in the red blood cells of brown trout was monitored under conditions of oxygen depletion and chemically induced anoxia. Although metabolic activity was reduced during anoxia to one-third of the normoxic value, these cells maintained their ATP contents stable and were viable for hours in the absence of oxygen. In addition, Na(+)-K(+) pump activity was not down-regulated when metabolic activity was reduced during anoxia. The compatibility of this finding with energy equilibrium and ion homeostasis was investigated.  (+info)

Energy cost of NaCl transport in isolated gills of cutthroat trout. (7/747)

Few studies have made direct estimates of the energy required for ion transport in gills of freshwater (FW) and seawater (SW) fish. Oxygen consumption was measured in excised gill tissue of FW-adapted cutthroat trout (Oncorhynchus clarki clarki) to estimate the energy cost of NaCl transport in that osmoregulatory organ. Ouabain (0.5 mM) and bafilomycin A1 (1 microM) were used to inhibit the Na+-K+ and H+ pumps, respectively. Both inhibitors significantly decreased gill tissue oxygen consumption, accounting for 37% of total tissue respiration. On a whole mass basis, the cost of NaCl uptake in the FW trout gill was estimated to be 1.8% of whole animal oxygen uptake. An isolated, saline-perfused gill arch preparation was also used to compare gill energetics in FW- and SW-adapted trout. The oxygen consumption of FW gills was significantly (33%) higher than SW gills. On a whole animal basis, total gill oxygen consumption in FW and SW trout accounted for 3.9 and 2.4% of resting metabolic rate, respectively. The results of both experiments suggest that the energy cost of NaCl transport in FW and SW trout gills represents a relatively small (<4%) portion of the animal's total energy budget.  (+info)

Latencies and discharge patterns of color-opponent neurons in the rainbow trout optic tectum. (8/747)

Although color-opponent neurons appear to subserve color vision, precisely how these cells encode hue is still not clear. Single-unit, extracellular recordings from the rainbow trout optic tectum were made in order to examine the possible role of action potential timing in coding chromatic stimuli. We found that color-opponent units can exhibit differences in response latency which are a function of wavelength and response sign, with the OFF response exhibiting the shorter response latency. We also found that units often responded with spike bursts characterized by early and late spikes separated by a silent period, with the relative proportion of early and late spikes varying as a function of wavelength. This type of discharge pattern appears to be a result of inhibitory, color-opponent processes. We suggest that complete inhibition of early spikes may be the mechanism underlying the observed latency differences. These findings suggest a role for action potential patterning in coding chromatic stimuli.  (+info)

I examined the spatial population dynamics of brook trout (Salvelinus fontinalis) in a central Appalachian watershed. The objectives of my research were: (1) identify factors that influence reproduction; (2) determine if factors that influence reproduction influence the distribution and abundance of juvenile and adults; and (3) to determine if the spatial arrangement of stream habitat influence growth, residency, and population fluctuation rates. I used visual surveys and redd counts to quantify spatial variation in habitat quality and brook trout spawning activity. I conducted a mark-recapture study over four seasons to quantify population parameters. The results of my research show that: (1) spawning occurred most often in the headwaters of Second Fork; (2) spawning intensity is a strong predictor of juvenile and small adult densities; and (3) growth and residency rates of juvenile and large adults was greatest in areas where the availability of spawning, feeding, and refuge habitats was greatest.
Networks of co-expressed genes produce complex phenotypes associated with functional novelty. Sex differences in gene expression levels or in the structure of gene co-expression networks can cause sexual dimorphism and may resolve sexually antagonistic selection. Here we used RNA-sequencing in the salmonid Brook Charr Salvelinus fontinalis to characterize sex-specific co-expression networks in the liver of 47 female and 53 male offspring. In both networks, modules were characterized for functional enrichment, hub gene identification, and associations with 15 growth, reproduction, and stress-related phenotypes. Modules were then evaluated for preservation in the opposite sex, and in the congener Arctic Charr Salvelinus alpinus. Overall, more transcripts were assigned to a module in the female network than in the male network, which coincided with higher inter-individual gene expression and phenotype variation in the females. Most modules were preserved between sexes and species, including those ...
Triiodothyronine and thyroxine levels and morphological parameters of fish were studied from January to May to evaluate the smoltification of yearling sea trout (Salmo trutta L.) raised in two different rearing systems (recirculating and flow-through) in three different hatcheries in Latvia. Thyroid hormone levels increased from January to May in both rearing systems in fish of different sizes. There was positive correlation between the degree of silvering and fish fork length and thyroid hormone levels, but there was no correlation between condition facor and thyroid hormone levels. Fish reared in recirculating systems were significantly larger (p , 0.05) and exhibited more visible signs of smoltification earlier than those reared in flow-through systems. The thyroid hormone levels and degree of silvering gradually became nearly the same by May in the sea trout from both rearing systems. Changes in thyroid hormone levels or fish size in spring cannot be evaluated separately from other signs to ...
We have studied the comparative rheology of individual red blood cells from humans and rainbow trout (Oncorhynchus mykiss) at their natural body temperatures. Trout red blood cells were large ellipsoids (about 16 microns x 11.5 microns x 2.5 microns) with a mean volume of 250 fl, a surface area of approximately 350 microns 2 and an elongated nucleus of about 9 microns x 5 microns. Although much larger than human red cells (diameter 8 microns, V = 92 fl, A = 136 microns 2), both theoretical calculation and experimental aspiration into micropipettes indicated that the limiting size of a cylindrical vessel that both types of cell could enter was approximately 3 microns. Nevertheless, individual trout red cells had much longer transit times through 5 microns filter pores and were much slower to enter 3-4 microns diameter micropipettes. Interestingly, the relative deformability of the trout cells depended on the pore size and applied pressure, with entry times for trout and human cells converging as ...

1. Variations in the glomerular filtration rate (G.F.R.) and the renal tubular reabsorption of water are probably important factors in the homoiostatic mechanisms associated with the euryhalinity of the rainbow trout (Salmo gairdneri).. 2. The observed reduction in urine flow after the adaptation of rainbow trout to sea water can be largely accounted for on the basis of the reduced G.F.R.. 3. Intraperitoneal injections of mammalian preparations of vasopressin, oxytocin and vasopressin/oxytocin into freshwater trout significantly increased the G.F.R.. 4. The intraperitoneal injection of aldosterone into freshwater fish had no detectable effect on G.F.R.. 5. The similar administration of corticosterone significantly reduced the G.F.R. to 73% of the intact freshwater control value.. ...
TY - JOUR. T1 - The blood circulatory function of the dorsal aorta ligament in Rainbow trout (Salmo gairdneri). AU - Priede, Imants George. PY - 1975/1. Y1 - 1975/1. N2 - An elastic longitudinal ligament stretched under considerable tension lies within the dorsal aorta of Rainbow trout. Experiments with mechanically simulated swimming movements in an artificial model demonstrate that such a ligament can act as a pump mechanism. The output of the pump increases with tail beat frequency up to a certain point where the mechanism tends to break down. Investigations on the trout dorsal aorta show that pump breakdown probably takes place at relatively low output pressures. Fundamental blood flow considerations indicate that a fully effective dorsal aorta pump over the full range of swimming speeds is undesirable. It is concluded that the dorsal aorta ligament can act as a pump which automatically increases circulation during swimming particularly to the body musculature. The output pressure is small ...

In this study I use a 56 years long dataset to study the migratory behaviours of a land-locked population of Brown trout (Salmo trutta) in the river Dammån, positioned in central Sweden. I found that there was a mean female-to-male sex ratio in the spawning-run of approximately 2.31 with an average 50% run date on the 29th of July.. I principally investigated if there were any trends in 3 different temporal scales: diel, seasonal and interannual. The model investigating diel effect was not significant, likely due to the light summer nights at this latitude. I found that there was a seasonal trend, where the probability of an observation being female increased by 54.33% during the season, indicative of a protandric trait where males gain from an early arrival to the spawning-grounds. The interannual model displayed a decline of 13.85% in the proportion of females migrating over the 56 years investigated.. ...
Poor water quality is discussed as a major factor causing a decline of brown trout populations in Swiss rivers. For our study we have chosen a river in the Swiss midlands, where the brown trout population has decreased dramatically during the last 10
Abstract: Southern brook trout (Salvelinus fontinalis) native to the Great Smoky Mountains are found in headwater streams. These habitats experience increased instances of stream acidification, lowering stream pH on average ~1.0 pH unit. It is well documented that lowering environmental pH results in fish experiencing systemic acidosis. We hypothesize that during acidification events, brook trout suffer acid/base perturbation. Previous studies on other species of freshwater fishes have demonstrated an alteration in the relative expression of H+-ATPase, NHE2 and NHE3 in gill tissue during pH disturbances. Due to a lack of physiological information available, the mechanism utilized by S. fontinalis to regulate systemic pH is unknown. We hypothesized that S. fontinalis will utilize H+-ATPase, NHE2 and NHE3 to excrete excess protons when experiencing episodic stream acidification. To date, we cloned ORFs for H+-ATPase, NHE2, and NHE3 which are homologous to rainbow trout (87, 94 and 92% identical ...

The aim of the research was to investigate the impact iodine solution disinfection had on Salmo trutta (L.) egg survival rates during incubation, and to determine the effect of the disinfection procedure on egg shells using scanning microscopy. The study groups were bathed in a Desamar K30 solution at a concentration of 100 ml per 10 dm-3 for 10 m once after the eggs had hardened and four times after the eyed stage. Egg samples for scanning analyses were collected on day 30 of incubation at the eyed stage after the first bath in the iodophor solution, and then at the end of incubation. Egg surface images were analyzed for the number of bacteria, the presence of hyphae, and the egg surface area covered with sediments. No statistically significant differences were noted in embryo survival rates in the groups that were disinfected. The highest number of bacteria was observed on egg surfaces which had not been disinfected prior to hatching. A significant amount of sediment was observed on the eggs ...
Reduced surface discharge negatively influences freshwater fish populations. Under the current flow regime management, the lower Cardrona River has experienced annual low flow events over the summer months. This low flow period has potential impacts on the wellbeing of the brown and rainbow trout populations in the river, as out-migrating juveniles may become stranded and subsequently experience high mortality rate during summer low flow. To estimate the impact of summer low flow on juvenile trout out-migration and to investigate how food availability and water temperature drive out-migration, brown and rainbow trout were sampled at three sites in the upper, middle and lower reaches of the Cardrona River, Central Otago, New Zealand in November 2016, January 2017 and April 2017; before, during and after a low flow event.. The density of juvenile trout was estimated at three sampling locations along the Cardrona River via single pass electric fishing. The results suggest juvenile trout were ...
Background: The relevance of immune-endocrine interactions to the regulation of ovarian function in teleosts is virtually unexplored. As part of the innate immune response during infection, a number of cytokines such as tumor necrosis factor alpha (TNF alpha) and other immune factors, are produced and act on the reproductive system. However, TNF alpha is also an important physiological player in the ovulatory process in mammals. In the present study, we have examined for the first time the effects of TNF alpha in vitro in preovulatory ovarian follicles of a teleost fish, the brown trout (Salmo trutta). Methods: To determine the in vivo regulation of TNF alpha expression in the ovary, preovulatory brook trout (Salvelinus fontinalis) were injected intraperitoneally with either saline or bacterial lipopolysaccharide (LPS). In control and recombinant trout TNF alpha (rtTNF alpha)-treated brown trout granulosa cells, we examined the percentage of apoptosis by flow cytometry analysis and cell ...

History of Brown Trout. Just when the divergence between the Atlantic salmon(salmo salar), and the brown trout(salmo trutta), occured is unknown, but there is large scientific evidence showing that they have a common ancestor. Recently found chromosome differences between the Atlantic salmon(56-58) and Salmo trutta(80) clearly separate the salmon and brown, but the similarity of the markings of the juveniles and parr (yearlings and fry) are strong evidence of a recent heritage. Behnkes recent research show that both brown and salmon have the same amount of DNA(weight). If the brown trout evolved by partial chromosome doubling, it should have 40% more DNA. Because the amount is approximately the same for both, it seems that the brown trout is the ancestral form and the Atlantic salmon is derived from it, by fusion of some of the chromosomes. The salmon has many long one-armed chromosomes, apparently a fusion of two-arm brown chromosomes. The brown trout is an extremely polymorphic species. This ...

We studied temporal allele frequency shifts over 15 years and estimated the genetically effective size of four natural populations of brown trout (Salmo trutta L.) on the basis of the variation at 14 polymorphic allozyme loci. The allele frequency differences between consecutive cohorts were significant in all four populations. There were no indications of natural selection, and we conclude that random genetic drift is the most likely cause of temporal allele frequency shifts at the loci examined. Effective population sizes were estimated from observed allele frequency shifts among cohorts, taking into consideration the demographic characteristics of each population. The estimated effective sizes of the four populations range from 52 to 480 individuals, and we conclude that the effective size of natural brown trout populations may differ considerably among lakes that are similar in size and other apparent characteristics. In spite of their different effective sizes all four populations have ...
Following confirmation of whirling disease in rainbow trout from the Watauga River in North Carolina, biologists with the N.C. Wildlife Resources Commission are concerned about potential significant impacts the disease may have on other trout populations, in particular native brook trout populations.. The disease, which is caused by a parasite, affects all species of trout and salmon; however, rainbow and brook trout, two species found in North Carolina waters, appear to be the most susceptible. Brook trout is the only trout species native to North Carolina, and it lives mainly in colder waters, which is also the preferred habitat of the parasite.. Despite their concern, biologists acknowledge that the presence of whirling disease doesnt necessarily equate to a dramatic loss of fish, given that other states where the disease has been present in waters for decades have been able to manage the disease so that impacts on both wild and stocked trout havent been nearly as devastating as previously ...
Beavers can negatively affect brook trout as well, albeit usually temporarily. Beaver dams can block fish passage, isolate populations, cause siltation, and increase predation by mammal and avian predators. As they dry up they can become dangerously, and even fatally, warm. While some problem dams last for only a few years, some, especially those in low-gradient areas, can remain in place for decades. And while blamed for giardiasis, or the dreaded beaver fever, the parasite that causes the malady, Giardia lamblia, is carried by birds, humans, and other animals as well as beavers.. Beaver ponds are considered by many anglers to be the Holy Grail of brook trout fishing. Finding a previously undiscovered beaver pond full of outsized brook trout is like winning the lottery. Once discovered, the location of a beaver pond is guarded like Jack Daniels guards its bourbon recipe. Writing a book about brook trout and not talking about beaver ponds would be like writing about baseball parks and not ...
Although the acid load has decreased throughout Scandinavia, acidic soils still mobilise aluminium (Al) that is harmful to brown trout. We hypothesise that there are thresholds for Al toxicity and that the toxicity can be traced from the water content to gill accumulation and the consequential physiological effects. During snowmelt, yearlings were exposed to a gradient of pH and inorganic monomeric Al (Al-i) in humic streams to study the toxic effects and mortality. Gill Al and physiological blood analyses [haemoglobin (Hb), plasma chloride (P-Cl) and glucose (Glu)] were measured. As the water quality deteriorated, Al accumulated on the gills; Hb and Glu increased; P-Cl decreased, and mortality occurred. Moribund fish had significantly increased gill Al and Hb, suggesting that respiratory disturbances contributed to mortality. Decreased P-C and plasma availability indicated an ion regulatory disturbance and possibly circulatory collapse. Al-i should be less than 20 mu g/L, and pH higher than ...

CPW is responsible for the preservation and protection of native and non-native wild trout populations. Most mountain streams and some high lakes in Colorado support populations of wild trout. These resources are important to the integrity of Colorados trout fisheries; as an indicator of properly functioning aquatic ecosystems; and for their intrinsic value to those seeking a unique, aesthetic and significant fishery resource. to assure the continuation and availability of wild self-sustaining trout populations the Parks and Wildlife Commission has established specific management guidelines for those aquatic habitats which support all life stages of trout. These waters are to be managed to the extent possible to maintain these wild trout populations.. ...
The Eastern Panhandle of West Virginia is drained by a portion of the mighty Potomac River, and has abundant trout resources. The region is graced with Karst, limestone geology that provides streams with cold buffered spring water. The panhandle boasts three intact native brook trout fisheries located within the Monongahela and the George Washington National Forests, and the area is a destination fishery for anglers throughout the East. TU is working to restore degraded riparian and in stream habitat to reconnect isolated headwater populations of brook trout back to the main stem rivers to increase size of the native fish and strengthen these populations.. In 2016, specific goals include:. •Reconnect 7 miles of headwater spring sources by mitigating three barriers to aquatic organism passage on brook trout streams.. •Restore 3 miles of in-stream habitat using rock and logs to create pools, runs and stabilize eroding stream banks. Restore 100 acres of riparian habitat by installing 10 miles ...

REGION A: SOUTHERN MAINE. Thirty years ago Sebago Lake was known for whitefish. But state fisheries biologist Francis Brautigam said after the wide use of pesticide, that fishery declined.. However, a week ago a 5-pound, 3-ounce whitefish was caught in the lake, Brautigam reported.. There is still a viable population. Its just not as abundant, said Brautigam with the Maine Department of Inland Fisheries and Wildlife.. REGION B: CENTRAL MAINE. State biologists are searching for prime wild brook trout habitat this time of year.. Biologist Bobby Van-Riper said there are as many as 75 wild brook trout streams in the region, mostly in more remote areas.. But those are getting hard to come by with development, he said.. REGION C: DOWN EAST. Biologists Down East also are busy doing stream surveys for wild brook trout.. Most are small in rural areas, said biologists Joe Overlock.. REGION D: WESTERN MAINE. IFW biologist Dave Boucher said fish will start moving from the lakes to the tributaries with ...

The Aurora trout is a freshwater fish and is under the jurisdiction of the federal government. The Species at Risk Act (SARA, Section 37) requires the competent minister to prepare recovery strategies for listed extirpated, endangered or threatened species. The Aurora trout was listed as endangered under SARA in May 2000. Fisheries and Oceans Canada - Central and Arctic Region, led the development of this recovery strategy. The strategy meets SARA requirements in terms of content and process (Sections 39-41).
Primary and secondary sex traits are influenced by the same sex hormones, and the expression of secondary sex traits may consequently signal males capacity for sperm production. Sperm quality may also be influenced by immune activity, as sperm are non-self to the male. Parasite infections alter immune activity and may thus reduce ejaculate quality. In the Arctic charr (Salvelinus alpinus) the red abdominal colour is considered an ornament that signals important information in mate choice. We captured and individually caged sexually mature male Arctic charr during the spawning period. Afterwards we estimated abdominal colour, parasite infections, gonad mass and several spermatological and immunological variables. Intensity of abdominal colour was positively correlated to testes mass, milt mass and sperm cell numbers produced. Additionally, males with low parasite intensities had high testes mass and produced milt with high sperm density, indicating a trade-off between parasite resistance and ...
The effects of water temperature and ammonia concentration on swimming capacity of brook charr (Salvelinus fontinalis, Mitchill, 1814) were determined by measuring gait transition speed (Ugt, cm/s), maximum burst speed (Umax, cm/s), tail-beat amplitude (a, cm), tail-beat frequency (f, Hz), maximum acceleration of bursts (Amax, cm/s2), number of bursts, distance of bursts (cm) and total swimming distance (cm) in a 4.5 m long experimental raceway with increasing upstream water velocity. Temperatures other than the acclimation temperature of 15 °C signi!cantly reduced swimming characteristics of gait transition, i.e. Ugt and Amax, while increased ammonia concentration reduced the measures of swimming after Ugt: Umax, the relationship between f and swimming speed above Ugt, a, Amax and the distance travelled with each swimming burst above Ugt. This study, using a novel raceway set-up shows various effects of temperature and ammonia exposure on the swimming performance of brook charr and can be used to
The only native species to our waters are the brook trout. This trout is really not a trout and is a member of the char family. Brook trout are known for their reckless abandon while feeding. At times they are too aggressive and some people dont fish for them because they consider them stupid. Their fins are bright red edged with white. The benchmark for a big brook trout in the area is 12 inches. Brook trout are currently at risk of extinction due to a Gill Lice Epidemic in driftless streams ...
The brown trout (lat.: Salmo trutta lacustris and trutta fario) belongs to the botanical family of Salmonidae or salmon-like fish. It is one of the most common trouts used as a food fish and belongs to the same species as the sea trout. The major differen
The effects of cypermethrin, copper and glyphosate on the endocrine system and subsequent response to female pheromones were investigated in mature male brown trout (Salmo trutta) parr. Responses measured were the amount of strippable milt, blood plasma levels of both an androgen (11-ketotestosterone (11-KT)) and a progestin (17α,20β-dihydroxy-4-pregnen-3-one (17,20b-P)), and behavioural changes. This was done in a two phased investigation where parr were exposed to one of the following via ambient water: 1) 0.1 or 1.0 μg L-1 cypermethrin, 2) 10 or 100 μg L-1 copper (Cu2+), or 3) 150 μg L-1 glyphosate for a 96 hour period. Phase one was a priming experiment exposing parr to a treatment followed by priming with PGF2α or ovarian fluid (OVF). Atlantic salmon (Salmo salar) parr were, also exposed to glyphosate during phase I. The second phase was centered on behavioural observations. Exposed parr were placed in a 35,000 L stream aquarium together with two ovulated females and four anadromous ...

THE name and fame of Dr. Samuel L. Mitchill have, in the absence of a complete biography, become to a considerable extent a tradition, known to few except students; yet, during the first quarter of this century, he was one of the most conspicuous figures in the literary and scientific life of the United States. He is called by Dr. J. W. Francis the Nestor of American science, and the pioneer philosopher in the promotion of natural science and medicine in America. He was a man of various attainments, and proved himself at home in many fields-in medicine, science, letters, politics, and social life.. Samuel Latham Mitchill was born in Hempstead, Long Island, August 20, 1769, and died in the city of New York, September 7, 1831. He was the third son of Robert Mitchill, an industrious farmer and member of the Society of Friends, and was remarkable for his habits of observation and reflection. His father seems to have taken less interest in his early instruction than his maternal uncle, Dr. Samuel ...
Aurora Trout are distinguished from other Brook Trout mainly in terms of skin colouration: (1) adult Aurora Trout lack the yellow spots and vermiculations that typically occur on the dorsal surface of other Brook Trout; and (2) the numerous red spots surrounded by blue halos characteristically found on the sides of Brook Trout are greatly reduced in number or are absent on Aurora Trout
We also angle for lake trout in addition to setting gillnets. As of today, we have caught twenty-two lake trout. For each lake trout caught, we weigh, measure, and scan for an internal PIT tag. Each tag has a unique identification number that lets us determine whether we have caught the trout before and if so, when. If the fish are in good shape, we release them back into the depths of the lake. The few lake trout that do not survive are dissected for otoliths (ear bones that tell us the trouts age), tissue samples, and diet analysis.. So far we have dissected three trout. Its not a huge number, but one we are hoping to minimize as we become savvier at quickly removing lake trout from gillnets. But here is the cool part: one of those 340 mm lake trout had a 120 mm lake trout in its stomach. A mushy, partially digested fish corpse probably doesnt sound exciting to you, but I could not be happier because we were able to extract its otoliths as well! The gillnets mesh is too large for the ...
One of the purposes of this study was to test in brown trout liver the spectrophotometric method originally used by Cablé et al. [13] for measurement of peroxisomal oxidase activities in mammalian tissues. However, some modifications were introduced and the method was extended to urate and glycolate oxidases. To calculate the amounts of H2O2 produced by these enzymes, instead of using the extinction coefficient previously published [13], a calibration line was made with known amounts of H2O2. Others also made similar calibration lines, but when using luminometric methods [15] and fluorometric techniques [16].. Since the physiological temperature is much lower in brown trout than in mammals, temperature influence in the activity of five peroxisomal enzymes was investigated. The results showed that the activities of these enzymes rose in a linear mode from 10 to 37°C, but while the activity of hydrogen peroxide producing oxidases were strongly influenced by temperature, catalase activity was ...

The novelties in the fish line this week are two brook trout and California salmon. Long Island cultivated trout, alive, sell for $1.50 a pound; killed $1 a pound; trout from other portions of the state, 75 cents; wild trout from the Adirondacks, 50 cents; Canada trout 25 to 35 cents. Certainly ten times as many trout are eaten in New-York as in former years. California salmon brought 45 cents a pound. This is rather a high price for California fish, but the catch is very light, caused by overfishing. (1879 ...
Brook trout are the ultimate indicators of the health of our lands and waters, said Chris Wood, TU Vice President for Conservation. Mercury and other airborne emissions are reflected in the growing number of fish consumption advisories on waters throughout New England. Water withdrawals and water quality degradation result in more streams with fewer trout. Urban sprawl and subdivisions into formerly forested areas deprive trout of the benefits of healthy streamside areas ...
Domesticated (farm) salmonid fishes display an increased willingness to accept risk while foraging, and achieve high growth rates not observed in nature. Theory predicts that elevated growth rates in domestic salmonids will result in greater risk-taking to access abundant food, but low survival in the presence of predators. In replicated whole-lake experiments, we observed that domestic trout (selected for high growth rates) took greater risks while foraging and grew faster than a wild strain. However, survival consequences for greater growth rates depended upon the predation environment. Domestic trout experienced greater survival when risk was low, but lower survival when risk was high. This suggests that animals with high intrinsic growth rates are selected against in populations with abundant predators, explaining the absence of such phenotypes in nature. This is, to our knowledge, the first large-scale field experiment to directly test this theory and simultaneously quantify the initial ...
This review summarizes the results of studies on atypical Aeromonas salmonicida (aAS) -infection among farmed Arctic charr (Salvelinus alpinus) and European grayling (Thymallus thymallus) (later referred as charr and grayling, respectively). Specifically, I aimed to characterize the causative agent of aAS -infection, to describe putative virulence factors of the bacteria and cross pathology of the infection in charr and grayling. I also aimed to describe some of the immune defense functions in charr. I also described a concomitant presence of a common fresh water fish parasite, Diplostomum spathaceum, and aAS -bacteria in manifestation of the bacterial infection. The experimental juvenile charr and grayling, originated from Vuoksi, Kymijoki and Inari watercourses in Finland. Several (n=66) aAS isolates from 7 watercourses in Finland and from the Baltic sea were characterized in the study. These were compared to 11 Swedish, 1 Icelandic aAS isolates, to 3 A. salmonicida subsp. salmonicida (ASS) ...
The response of six species of freshwater fish, from the families Cyprinidae (common carp Cyprinus carpio; roach Rutilus rutilus; chub Leuciscus cephalus) and Salmonidae (rainbow trout Oncorhynchus mykiss; brown trout Salmo trutta; Arctic charr Salvelinus alpinus), to a standardised stressor was evaluated. A six hour period of confinement resulted in changes to plasma cortisol, glucose, amino acid and lactate levels compared to unconfined controls. There were significant differences in the response profiles both within and between families. The cyprinid species exhibited higher and more sustained stress-induced increases in plasma cortisol and glucose than the salmonid species. In cyprinids plasma lactate and plasma amino acid concentration showed less disturbance following stress than in salmonids. The results of the study, together with an evaluation of previously published data for eight salmonid species and six cyprinid species support the hypothesis that differences in core elements of the ...
Infectious pancreatic necrosis (IPN) is an acute, contagious disease of trout fry and fingerlings caused by viruses of the family birnaviridae. IPN disease usually results in mortality that is inversely proportional to the age of the fish. While many studies have been carried out to increase our understanding of IPN, little is known about its virulence characteristics for some subtypes common to the Pacific Northwest region of the United States. Knowledge of relationships between IPN virus subtypes, epitope patterns and virulence patterns could be useful for developing a successful IPNV vaccine. This study investigated virulence characteristics of IPN viruses in brook trout, Salvelinus fontinalis, fry, using fish mortality, virus titer in fish tissue, and the presence of clinical signs of IPN as indicators of virulence. The relationship between virulence and different IPN virus subtypes, and specific epitopes, or monoclonal antibody binding sites, was also addressed. An additional study focused ...

Formalin, malachite green, or a mixture of them are utilized in fish culture for control of external parasites of fish and control of fungus on fish and fish eggs. Very little information is available concerning the toxicity of these compounds to fish under laboratory test conditions or the differences in sensitivity to these chemicals at various life stages. This study was designed to 1) determine the toxicity of formalin, malachite green and the mixture to four life stages of rainbow trout (Salmo gairdneri) under various laboratory test conditions, 2) determine the degradation of formalin and malachite green in water, 3) determine the effect of additive toxicity, and 4) determine the differences in sensitivity of two different lots of eggs to the chemicals. The 96-hour LC50 (lethal concentration required to produce 50% mortality) for formalin against rainbow trout in soft water ranged from 580 micrograms/liter for the eyed egg stage to 134 micrograms/liter for the fingerling stage. The 96-hour ...
1. Intravenous injection of heparin into the trout resulted in the appearance in the plasma of a lipase with the properties of lipoprotein lipase. 2. The enzyme was purified to apparent electrophoretic homogeneity by means of heparin-Sepharose affinity chromatography. The enzyme was eluted with 1.5 M-NaCl and had a specific activity approx. 450-fold that of the post-heparin plasma. 3. The activity of the purified enzyme was inhibited by 1.0 M-NaCl and protamine sulphate and was stimulated between 3- and 8.8-fold by the addition of trout plasma. 4. The activity was strongly stimulated by trout very low density lipoproteins and to a lesser extent by high density lipoproteins. 5. The isolated enzyme fraction gave a single band on sodium dodecyl sulphate/polyacrylamide-gel electrophoresis and had an apparent subunit M4 of 63 000. 6. These results suggest that the uptake of lipid by the tissues in the trout can occur by a process similar to that in mammals. ...
ABSTRACT: Acanthocephalan parasites were collected from the intestinal tracts of 137 predominantly wild fish (1 barbel Barbus barbus, 3 European chub Squalius cephalus, 13 rainbow trout Oncorhynchus mykiss and 120 brown trout Salmo trutta) from 12 localities. The condition factor, intensity of acanthocephalan infection and pathological lesions, if applicable, were documented. Routine bacteriology and virology were performed, and the brown trout were additionally tested for the presence of the myxozoan parasite Tetracapsolioides bryosalmonae by PCR. In total, 113 acanthocephalans were barcoded by sequencing a section of the mitochondrial cytochrome oxidase subunit I (COI) gene. Barcoding of the acanthocephalan tissues resulted in 77 sequences, of which 56 were assigned to Echinorhynchus truttae (3 genotypes), 11 to Pomphorhynchus tereticollis (9 genotypes), 9 to Acanthocephalus sp. (5 genotypes) and 1 to Neoechinorhynchida. Most of these genotypes were detected for the first time. Statistically, ...
Department fisheries biologists sampled and monitored 33 streams in northeastern Vermont to determine what factors make for a good brook trout stream. The study indicated water temperature and the amount of wood per acre were the best predictors of brook trout abundance.. Based on this study, biologists are deliberately adding natural wood to selected streams where these important habitats features are lacking, and monitoring these streams to determine if this practice can effectively improve trout populations. The results are promising.. adding wood to the Nulhegan river ...
Background Over the last two decades, there has been a constant increase in prescription rates of antidepressants. In parallel, neuroactive pharmaceuticals are making their way into aquatic environments at increasing concentrations. Among the antidepressants detected in the environment citalopram, a selective serotonin reuptake inhibitor, is one of the most commonly found. Given citalopram is specifically designed to alter mood and behaviour in humans, there is growing concern it can adversely affect the behaviour on non-target wildlife Methods In our study, brown trout were exposed to citalopram (nominal concentrations: 1, 10, 100, 1000 µg/L) in two different life stages. Larvae were exposed at 7 and 11 °C from the eyed ova stage until 8 weeks post yolk sac consumption, and juvenile brown trout were exposed for 4 weeks at 7 °C. At both stages we measured mortality, weight, length, tissue citalopram concentration, behaviour during exposure and behaviour in a stressfull environment. For brown trout
Changes in Species Interactions. The introduction of new species is not the only threat posed by climate change. Many alien species are not invasive, instead existing in sympatry with native species. However an increase in temperature, or an increase in disturbance caused by extreme weather events, could change this. Alien species that are able to establish themselves in novel ecosystems often have higher levels of adaptability, which could mean that in the face of increased disturbance they would gain a competitive advantage.. Likewise, increasing temperature may favour one species over another. A classic example of this is the northern pike (Esox lucius), which was recognised as a regionally alien species by Norwegian Institute Artsdatabanken for the first time this year. Previously, the pike and the brown trout (Salmo trutta) were able to coexist in many freshwater lakes, however with increasing temperatures, pike have been able to outcompete the trout, with many local extinctions of the ...
Conclusions: At small spatial scales, where extirpation risks are high, landscape fragmentation will likely have long-term negative consequences on the genetic variation of individual assemblages of coastal cutthroat trout. Thresholds/Learnings: Synopsis: This study aimed to determine if coastal cutthroat trout were genetically structured within streams and to assess the effects of habitat fragmentation on coastal cutthroat trout genetic variation. Habitat fragmented by roads and other human disturbances acted as dispersal barriers, which strongly influenced coastal cutthroat trout genetic structure, diversity, and differentiation. At range-wide spatial scales, fragmentation potentially contributes to coastal cutthroat trout genetic diversity, and it is not recommended that natural barriers be modified for fish passage. However, at small spatial scales, where extirpation risks are high, fragmentation will likely have long-term negative consequences on the genetic variation of individual assemblages of

Toxaphene is reported to cause defects in the collagen of fish. Chronic exposure to toxhaphene weakens the backbone of fish by decreasing the amount of collagen and usually increasing the amount of calcium in the bone which results in a more brittle and fragile bone. We investigated the possible direct action of toxaphene on collagen synthesis by exposing vertebral and swim bladder organ cultures obtained from unexposed rainbow trout (Salmo gairdneri) fingerlings to the same lot of toxaphene found to cause this defect in vivio. Collagen produced by these organ cultures was measured by: (1) total 3H-proline incorporated into the matrix; (2) 3H-proline released during collagenase digestion of acid-precipitated protein; (3) 3H-hydroxyproline extracted from the acid hydrolysate, and (4) tritiated water produced during the hydroxylation of 4-3H-proline. At a relatively high concentration of toxaphene (2.4 mM) these indices of collagen production were reduced, but this was probably caused by a decrease in

Nine percent of the rainbow trout (Salmo gairdneri) from a hatchery source have a greater than 100-fold increase in expression of a phosphoglucomutase (PGM) locus, Pgm1, in the liver but have normal expression of this locus in other tissues. The results of genetic crosses are consistent with a single regulatory gene with additive inheritance being responsible for the differences in the amount of PGM activity in the liver.-The allele responsible for the expression of Pgm1 in the liver is apparently a recent mutation. This is supported by its restricted distribution in rainbow trout and the absence of liver Pgm1 expression in closely related species. This genetic system is valuable for future analysis of the control of gene expression and in determining the relative evolutionary importance of genetic variation at structural and regulatory genes.. ...

For decades beginning in the 1920s Parks Canada stocked water bodies in Banff National Park with various species of fish including eastern brook trout, lake trout, rainbow trout and Yellowstone cutthroat trout.
Clonal lines of rainbow trout have been developed at Washington State University using the chromosome set manipulation techniques of androgenesis and gynogenesis. Androgenesis involves irradiating eggs with gamma radiation before fertilization, followed by a heat or pressure shock treatment to block the first cleavage division. An advantage of androgenesis is that it allows lines to be recovered from cryopreserved sperm. The isogenicity of the lines has been confirmed using multilocus RFLP studies (3,7).. Rainbow trout are a major biomedical research animal for cancer, immunology and toxiciology research. They are also advantageous because of the large amount of research that has been carried out with them related to aquaculture and sport fisheries. Rainbow trout are native to the Pacific coast of North America and Siberia and significant native populations till exist throughout much of the species range. ...
ABSTRACT = { Whole genome duplication (WGD) can provide material for evolutionary innovation. Family Salmonidae is ideal for studying the effects ofWGD as the ancestral salmonid underwentWGD relatively recently, ~65Ma, then rediploidized and diversified. Extensive synteny between homologous chromosome arms occurs in extant salmonids, but each species has both conserved and unique chromosomearmfusionsandfissions. Assemblyof large,outbred eukaryoticgenomescanbedifficult, but structural rearrangements within such taxa can be investigated using linkage maps. RAD sequencing provides unprecedented ability to generate high-density linkage maps for nonmodel species, but can result in low numbers of homologous markers between species due to phylogenetic distance or differences in library preparation. Here,we generate a high-density linkagemap (3,826 markers) for the Salvelinus genera (Brook Charr S. fontinalis), and then identify corresponding chromosome arms among the other available salmonid ...
TY - JOUR. T1 - Rainbow trout suppressor of cytokine signalling (SOCS)-1, 2 and 3. T2 - molecular identification, expression and modulation. AU - Wang, Tiehui. AU - Secombes, Christopher J. PY - 2008/3. Y1 - 2008/3. N2 - Suppressor of cytokine signalling (SOCS) proteins are inhibitors of cytokine signalling pathways. Three SOCS genes, SOCS-1, 2 and 3, have been identified and their sequences analyzed in an economically important fish, rainbow trout (Oncorhynchus mykiss, Walbaum). In general, these three SOCS molecules are well conserved especially in the SRC homology 2 and the SOCS domains, with sequence identities between trout and mammals ranging from 41 to 42, 50 to 51, and 58 to 61% for SOCS-1, 2 and 3, respectively. The identities within fish species are slightly higher, with sequence identities between trout and the other fish species at 44-46, 64-70, and 71-76% for SOCS-1, 2 and 3, respectively. All the SOCS-1, as well as all the SOCS-2 or 3 molecules from different species are grouped ...
Each year the Discovery Museum participates in Trout Unlimiteds Trout in the Classroom program. Trout in the Classroom is a unique conservation-oriented education program that engages K-12 students in local ecology and stream health, trout life cycles and biology, and the delicate balance of a local ecosystem.. In October, Trout in the Classroom delivered fertilized trout eggs to the Discovery Museum. The eggs hatched in an aquarium equipped with a special chiller designed to keep the water near 50 degrees F. If youve visited the Shenandoah Valley Discovery Museum during the last six months, youve seen our brook trout go through part of their life cycles, hatching from eyed eggs and moving through the alevin and fry stages to become fingerlings. While at the museum, you may even have helped Mr. Rick as he took daily water temperature measurements and monitored water pH and ammonia levels with test kits. There are still approximately 12 brook trout growing in the aquarium at the Shenandoah ...
Acute fish toxicity In order to test possible acute effects of DMA on fish, Salmo gairdneri was chosen as test organism in an experiment conducted by Calamari et al. (1980) according to guideline ISRA (Rome, 1973): Saggio di tossicita con animali acquatici. Using hard water a LC50 (96h) of 118 mg/L was determined, whereas using soft water a LC50 (96h) of 17 mg/L is reported, respectively. Brachydanio rerio eggs were observed for 96 hours beginning with the 8 cell stage (Groth, et al., 1993). In this experiment LC50 of 396.7 mg/L, LC100 of 4508 mg/L, and NOEL of 45.08 mg/L are reported as results. Furthermore, Pecilia reticulata was investigated according to OECD Guideline 203 (Van Leeuwen et al., 1985), resulting in a LC50(96h) value of 210 mg/L. Chronic fish toxicity To investigate the long-term effects of dimethylamine towards fish, juvenile Salmo gairdneri were exposed to different concentrations of the test substance for 30 days (Calamari, 1979). As result a NOEC of 20 mg/L was ...
A method has been developed for the continuous automated monitoring of cardiac output in adult rainbow trout. Average cardiac output measured under control conditions and varied environmental conditions of hypoxia and post-hypoxia was significantly higher (P≤ 0.05) in male than female trout. The cardiac output of trout in spawning condition was significantly higher (P≤ 0.05) than that of trout not in spawning condition. Measurements of pulsatile cardiac output were made simultaneously with trout ventilation, and revealed ventilatory interactions with blood flow that varied depending on environmental oxygen condition. The method for monitoring gill blood flow was used with methods for automated measurement of gill water flow, oxygen uptake, and chemical flux in vivo. An experimental protocol was developed in which environmental oxygen was varied to obtain maximum increases in water flow over the gills without blood flow changes, and subsequent attainment of maximum increases in blood flow ...
Little is known about the factors that drive the high levels of between-host variation in pathogen burden that are frequently observed in viral infections. Here, two factors thought to impact viral load variability, host genetic diversity and stochastic processes linked with viral entry into the host, were examined. This work was conducted with the aquatic vertebrate virus, Infectious hematopoietic necrosis virus (IHNV), in its natural host, rainbow trout. It was found that in controlled in vivo infections of IHNV, a suggestive trend of reduced between-fish viral load variation was observed in a clonal population of isogenic trout compared to a genetically diverse population of out-bred trout. However, this trend was not statistically significant for any of the four viral genotypes examined, and high levels of fish-to-fish variation persisted even in the isogenic trout population. A decrease in fish-to-fish viral load variation was also observed in virus injection challenges that bypassed...
775) 778-3159. Madam Chairwoman and Members of the Committee, I appreciate the opportunity to testify before this committee on this important matter. Trout Unlimited is a national organization dedicated to the protection and restoration of trout and salmon and their habitats. In Nevada alone, over 650 Trout Unlimited members volunteer their time and resources to protect and enhance the states streams, rivers and watersheds. Nationally, we have over 100,000 members and 500 chapters with a long track record of working with local communities, states and federal agencies to seek sound solutions to environmental challenges.. First, allow me to briefly describe our memberships connection to this hearing today. The Jarbidge River is of particular concern to Trout Unlimited members in Elko County and the rest of Nevada. The river is home to the southernmost population of bull trout in North America, and TU has worked hard on the ground to improve conditions for the fish. Two years ago, the ...

Nel presente lavoro sono riportati i risultati di unanalisi citogenetica eseguita su popolazioni italiane di trota fario (Salmo trutta complex) utilizzando colorazioni convenzionali, tecniche di bandeggio e ibridazione in situ (FISH) con sonde fluorescenti. Tutti gli individui esaminati, appartenenti alle linee evolutive Atlantica (At), Marmoratus (Ma), Adriatica (Ad) e Mediterranea, hanno mostrato una considerevole stabilità cromosomica, con un complemento diploide pari a 2n = 80 cromosomi, numero fondamentale pari a 102 e una sostanziale uniformità morfologica delle varie coppie di omologhi. Tale uniformità ha riguardato anche la localizzazione del DNA ribosomiale 5S e dei siti NOR attivi. Al contrario, la FISH con una sonda di DNA ribosomiale 28S e la colorazione col fluorocromo CMA3 ha mostrato che i siti NOR inattivi sono più numerosi nelle linee evolutive Ad e Me rispetto alle linee At e Ma. Poiché le sequenze centromeriche sono altamante conservate nei Salmonidi, si è deciso di ...
Guess who spawns first? The rainbow. Adult rainbows begin to concentrate on spawning in late March on the Kenai and the spawn seems to last throughout April and into May. The fish congregate in certain distinct gravel laden sections of the river, many of which will host returning salmon in the coming months. From the air, I have surveyed these packs of rainbow trout. They school together in large groups when the river is just shedding winter ice and snow and flows are low and clear. Many are the size of salmon and larger, indeed the Kenai is the home to a monstrous strain of rainbow trout. Some become easy picking for hungry eagle as their backs dimple the shallow waters near the rivers edge while spawning. Perhaps at no other portion of the year do so many of the rivers large rainbows congregate in the same place and there can be no doubt that many fish over twenty pounds are present. Wisely ADF&G closes trout fishing between April 15 and June 16 to allow the trout ample time to complete their ...
There is no reason to segment the abdomen area, as far as I know, the trout dont care so why do it? Baetis nymphs move around fairly fast in the water column, they are a swimmer type mayfly nymph and when swimming to emerger in the drift of the stream, trout dont have time to inspect them that closely. Besides, if there is a good Baetis hatch trout will stuff themselves as fast as they can. The supply and demand for food and its BRIEF availability means trout have to make the best out of the energy they expend VS the energy gained in order to survive. That means trout will gobble up any food item as fast as they can when a food item is available in mass quantity ...
According to a copy of the draft of her epitaph for her funeral, Mary Susan spent the last three years of her life in a coma. Excerpts from the autobiography Moms Ramblings by Bonnie Brooks Hartman, descendent of Susan Rebecca Brooks (recorded by son John F.

The family had owned slaves, but Marys fathers had freed them, but they wouldnt go anywhere. They wanted to stay on, even before the Civil War started. A few of them wanted to live with Miss Mary when she married Middleton and moved to Alabama. From notes of Anne Wise Hood, descendent of Sarah Frances Brook and A.J. Wise, written by Ethel Holloway, daughter of Mary Clara Halstead (daughter of Mary A. Brooks and Newton Jasper Halstead, granddaughter of Mary Susan Wilkes and Middleton Brooks): Polly (Mary Susan) is described as about medium height, slender, with blue-gray eyes in a long ...

BREVARD, N.C. (Aug. 19, 2015) - The N.C. Wildlife Resources Commission resumed stocking Hatchery Supported trout waters today after receiving confirmation that trout from Armstrong State Fish Hatchery in Marion and Setzer State Fish Hatchery in Brevard tested negative for whirling disease, a disorder affecting trout. Whirling disease affects fish in the trout and salmon family. The disease, caused by the microscopic parasite, Myxobolus cerebralis, damages cartilage and skeletal tissue in a fish, causing it to swim in a whirling motion. While often fatal to juvenile fish, the disease does not infect humans or pets, and eating an infected fish is not known to cause any harmful effects. The Commission will not retroactively stock Hatchery Supported locations that did not receive fish during the hatchery-testing period due to recent drought conditions and concerns of high water temperatures at those locations. The Commission also has implemented safeguards to reduce the chance of the parasite being ...

TRAVERSE CITY, Mich. - A state judge has sided with a northern Michigan fish growing company that wants to dramatically increase production of rainbow trout on the Au Sable River, turning aside objections that the expansion would pollute the prized waterway.. Administrative Law Judge Daniel Pulter endorsed with slight modifications a 2014 permit issued by the Department of Environmental Quality that would allow Harrietta Hills Trout Farm LLC eventually to raise its output to 300,000 pounds of trout annually at its Grayling facility - up from 20,000 pounds a few years ago.. Company owner Dan Vogler says the expansion is needed to keep the business profitable and would draw more tourists, boosting the local economy. A group called Anglers of the Au Sable and the Sierra Club challenged the permit, saying the operation would discharge feces and uneaten fish food to the river, degrading water quality and potentially exposing wild trout to a deadly parasitic disease.. John Flesher reports for the ...
The changes in gene transcription at all assayed genes in response to the challenges in our study indicate that the genes we studied are responding to stress. Many of these genes have previously been demonstrated to respond to stress or immune challenge in other studies (e.g., Wiseman et al. 2007; Raida and Buchmann 2009). The different patterns of response and resting transcription we observed among populations suggest that diverging evolutionary processes (i.e., not stabilizing selection) are contributing to the variation among Babine Lake rainbow trout tributary populations. Population structure is present among Babine Lake rainbow trout tributary populations and neutral divergence in this system follows a pattern of isolation by distance (Koehler 2010); however, the lack of consistent clinal variation in gene transcription observed across a geographic gradient suggests, but does not preclude, that the differences are not a result of genetic drift. Local adaptation can occur when gene flow is ...
The tumour suppressor protein p53 is a critical protein in the DNA damage checkpoint pathway. It acts as a transcription factor that is involved in initiating the apoptotic pathway; disruption of this pathway can lead to various forms of cancer. Due to its importance in cancer prevention, p53 has been extensively studied, though only a small fraction of these studies have been in non-mammalian models. Some previous studies of p53 expression and regulation in lower vertebrate species have shown potential differences in its control, in comparison to the better characterized mammalian pathways. These differences emphasize the need to further investigate its mechanism of action in lower vertebrate models. To evaluate its biomarker potential for aquatic toxicology studies, two rainbow trout cell lines (RTbrain-W1 and RTgill-W1) were used in dose response experiments using DNA damage checkpoint inducing agents: bleomycin, hydroxyurea, and methyl methanesulfonate. For our studies, a rainbow trout ...

Judge Margaret McKeown, writing for the court, said the parties agree that dams and more than 100 point-source discharges into the two rivers are the cause of rising water temperatures.. Moreover, she said, [t]emperatures are projected to rise with increased human activity on the rivers, furthering endangering salmon and trout populations.. The Columbia and Snake rivers were historically home to some of the most prolific salmon and steelhead runs in the world. Some 10 million to 16 million of the fish returned to the river system every year, and the Snake River, a Columbia tributary, produced nearly half of those runs.. Salmon and steelhead runs plummeted beginning in the 1960s due to several factors: rapid dam building, commercial harvest and other development (Greenwire, Sept. 25).. Today, the salmon and steelhead runs on the Snake River are particularly imperiled, leading environmental groups to take new legal action including this case.. McKeown noted that Washington, Oregon and EPA have ...

During the 2009 offseason, Liriano returned to his native Dominican Republic to play winter baseball, playing for Leones del Escogido. Liriano helped his club earn a postseason berth and then went 3-1 with a 0.49 ERA in seven playoff starts, while recording 47 strikeouts and five walks in 37 innings, as Leones del Escogido won the league championship.. Liriano reported to spring training lighter than usual, and Twins coaches expressed guarded optimism that Liriano had regained some of his 2006 form.[6] The Twins considered using Liriano as a closer to replace the injured Joe Nathan, but instead he was named to the starting rotation.. Liriano got off to a fast start. In Liriano's first four 2010 starts for the Twins, he posted a 3-0 W-L record, 0.93 ERA with 27 strikeouts. On May 3, 2010, he was named the American League pitcher of the month for April. Through May 18, Liriano had posted a 4-2 record and a 2.63 ERA..

He began his major league career on September 6, 1968, but did not have his first full year until 1970. In 1969, he suffered a severe injury while serving in the Marine Reserves, at Camp Pendleton in California. May was cleaning a mortar gun when it fired causing a partial amputation of his right thumb.[1] He won the Sporting News Rookie of the Year Award, but lost to Lou Piniella for the Major League Baseball Rookie of the Year Award. In 1970, as the White Sox' full-time left fielder, he had a good breakout season, batting .285 with 12 home runs and 68 RBIs. However, the White Sox had a miserable year, finishing 50 games under .500 and in last place in the American League, 42 games out of first place. In 1971 he batted .294 with 70 RBIs while playing regularly at first base for the only time in his career. He moved back to the outfield after an offseason trade brought superstar Dick Allen to the White Sox.[2] Throughout the early 1970s, May continued to help the White Sox improve as a solid ...
