AU - Kubo, Yoshihiro. AU - Konno, Norifumi. AU - Joss, Jean M P. PY - 2012. Y1 - 2012. N2 - Epithelial sodium channel (ENaC) is a Na+-selective, aldosterone-stimulated ion channel involved in sodium transport homeostasis. ENaC is rate-limiting for Na+ absorption in the epithelia of osmoregulatory organs of tetrapods. Although the ENaC/degenerin gene family is proposed to be present in metazoans, no orthologues or paralogues for ENaC have been found in the genome databases of teleosts. We studied full-length cDNA cloning and tissue distributions of ENaCα, β and γ subunits in the Australian lungfish, Neoceratodus forsteri, which is the closest living relative of tetrapods. Neoceratodus ENaC (nENaC) comprised three subunits: nENaCα, β and γ proteins. The nENaCα, β and γ subunits are closely related to ...
Lepisosteus is a genus of gars in the family Lepisosteidae. While in the present day, Lepisosteus is only known across North America, fossil remains show it was much more widespread in the past, with specimens known from the Cretaceous of India and Brazil. The currently recognized species are: †Lepisosteus aganus (Cope 1877) †Lepisosteus bemisi Grande 2010 †Lepisosteus bohemicus (Laube 1901) †Lepisosteus cominatoi Santos 1984 †Lepisosteus cycliferus (Cope 1873) †Lepisosteus glaber Marsh 1871 †Lepisosteus indicus Woodward 1908 †Lepisosteus integer (Cope 1877) †Lepisosteus fimbriatus Wood 1846 †Lepisosteus knieskerni Fowler 1911 †Lepisosteus longus Lambe 1908 †Lepisosteus nahunticus (Cope 1869) †Lepisosteus notabilis Leidy 1873 †Lepisosteus opertus Estes 1964 †Lepisosteus strausi Kinkelin 1884 †Lepisosteus suessoniensis Gervais 1888 †Lepisosteus whitneyi Marsh 1871 Lepisosteus oculatus Winchell 1864 (Spotted gar) Lepisosteus osseus Linnaeus 1758 (Longnose gar) ...
One of the greatest challenges facing the early land vertebrates was the need to effectively interpret a terrestrial environment. Interpretation was based on ocular adaptations evolved for an aquatic environment millions of years earlier. The Australian lungfish Neoceratodus forsteri is thought to be the closest living relative to the first terrestrial vertebrate, and yet nothing is known about the visual pigments present in lungfish or the early tetrapods. Here we identify and characterise five visual pigments (rh1, rh2, lws, sws1 and sws2) expressed in the retina of N. forsteri. Phylogenetic analysis of the molecular evolution of lungfish and other vertebrate visual pigment genes indicates a closer relationship between lungfish and amphibian pigments than to pigments in teleost fishes. However, the relationship between lungfish, the coelacanth and tetrapods could not be absolutely determined from opsin phylogeny, supporting an unresolved trichotomy between the three groups. The presence of four cone
The neuropeptide Y (NPY) family receptors and peptides have previously been characterized in several tetrapods, teleost fishes, and in a holocephalan cartilaginous fish. This has shown that the ancestral NPY system in the jawed vertebrates consisted of the peptides NPY and peptide YY (PYY) and seven G-protein-coupled receptors named Y1-Y8 (Y3 does not exist). The different vertebrate lineages have subsequently lost or gained a few receptor genes. For instance, the human genome has lost three of the seven receptors while the zebrafish has lost two and gained two receptor genes. Here we describe the NPY system of a representative of an early diverging lineage among the sarcopterygians, the West Indian Ocean coelacanth Latimeria chalumnae. The coelacanth was found to have retained all seven receptors from the ancestral jawed vertebrate. The receptors display the typical characteristics found in other vertebrates. Interestingly, the coelacanth was found to have the local duplicate of the PYY gene, ...
In many marine fish species, genetic population structure is typically weak because populations are large, evolutionarily young and have a high potential for gene flow. We tested whether genetic markers influenced by natural selection are more efficient than the presumed neutral genetic markers to detect population structure in Atlantic herring (Clupea harengus), a migratory pelagic species with large effective population sizes. We compared the spatial and temporal patterns of divergence and statistical power of three traditional genetic marker types, microsatellites, allozymes and mitochondrial DNA, with one microsatellite locus, Cpa112, previously shown to be influenced by divergent selection associated with salinity, and one locus located in the major histocompatibility complex class IIA (MHC-IIA) gene, using the same individuals across analyses. Samples were collected in 2002 and 2003 at two locations in the North Sea, one location in the Skagerrak and one location in the low-saline Baltic ...
Some fresh water lobe-finned மீன் (Sarcopterygii) develop legs and give rise to the நாற்காலி (உயிரியல்).. The first tetrapods evolved in shallow and swampy நன்னீர் habitats.. Primitive tetrapods developed from a lobe-finned fish (an osteolepid Sarcopterygian), with a two-lobed மனித மூளை in a flattened skull, a wide mouth and a short snout, whose upward-facing eyes show that it was a bottom-dweller, and which had already developed adaptations of fins with fleshy bases and எலும்புs. The living fossil coelacanth is a related lobe-finned fish without these shallow-water adaptations. These fishes used their fins as paddles in shallow-water habitats choked with plants and detritus. The universal tetrapod characteristics of front limbs that bend backward at the elbow and hind limbs that bend forward at the knee can plausibly be traced to early tetrapods living in shallow water.[6]. Panderichthys is a 90-130 cm ...

Recently, commercial aquaculture farms in Northern California have exposed gravid, cultured white sturgeon females to cold water (12 ?? 1??C) throughout the late phase of vitellogenesis and ovarian follicle maturation resulting in improved ovulation rates and egg quality. However, the optimum timing for transfer of broodfish to the cold water and the capacity of transferred broodfish to maintain reproductive competence over an extended time in cold water had not been evaluated. Gravid white sturgeon females that have been raised at water temperatures of 16-20??C were transported to either cold water (12 ?? 1??C; Group 1) in November 1997 or maintained in ambient water temperatures (10-19??C; Group 2) until early spring. In March 1998, half of the fish in Group 2 had regressed ovaries, but the remaining females had intact ovarian follicles and were transported to the cold water. Ovarian follicles and blood were collected from females until they reached the...

Characterization of the immunoglobulin (Ig) light (L) and heavy (H) chain genes from the Siberiansturgeon, Acipenser baeri, revealed an Ig structure simhar to the IgM elass of mammals. The serumforms of the sturgeon Ig are tetrameric and dimeric.. The sturgeon IgL gene organization is also of the translocon type, with several variable (V)segments followed by some joining (J) segments and the constant (C) exon indicate that theformation of IgL multicluster organisations in teleosts and elasmobranchs are two separateevolutionary events. The sturgeon VL segments all belong to a single family with some 20 members.Light chain variability is generated by random rearrangement of the VL and J segments. The sturgeon IgL is classified as κ like based on homologies of the VL sequence, and similarities of the recombination signal sequence.. The genomic organization of the IgH locus in sturgeon is of the translocon type. withmultiple V gene segments preceeding several D segments, a number of J segments ...
But if youre after two cool tidbits, know that the Australian Lungfish is essentially a living fossil. Fossilized evidence of its family members date back to the Devonian, and the Australian Lungfish itself has remained relatively unchanged for nearly 100 million years! There are five other Lungfish species still alive, and one of their closest lobe-finned relatives is the Coelacanth. Lobe-Finned fish are especially notable because it is from them that tetrapods eventually evolved ...
The Queensland lungfish (Neoceratodus forsteri), also known as the Australian lungfish, Burnett salmon and barramunda, is a surviving member of the family Neoceratodontidae and order Ceratodontiformes. It is one of only six extant lungfish species in the world. Endemic to Australia, the Neoceratodontidae are an ancient family belonging to the class Sarcopterygii, or lobe-finned fishes. Fossil records of this group date back 380 million years, around the time when the higher vertebrate classes were beginning to evolve. Fossils of lungfish almost identical to this species have been uncovered in northern New South Wales, indicating that Neoceratodus has remained virtually unchanged for well over 100 million years, making it a living fossil and one of the oldest living vertebrate genera on the planet. It is one of six extant representatives of the ancient air-breathing Dipnoi (lungfishes) that flourished during the Devonian period (about 413-365 million years ago) and is the most primitive surviving ...

In the last three decades, several ecological factors were changed and affected the most important commercial fish stocks in the Caspian Sea. This paper aims to assess the effects of these pressures on the population structure, stock status and the vulnerability risk of stock extinction of the stellate sturgeon(Acipenser stellatus Pallas, 1771) in the Southern Caspian Sea, in the years 1990-2011. For this period, we estimated growth parameters, the age structure of catch, sexual maturity, age at first capture, natural and fishing mortality, biomass and risk of stock extinction of stellate sturgeon by IUCN Red List categories. Fork lengths of individuals ranged from 82 to 206 cm and ages from 4 to 29 years. The growth parameters were L∞=215.0 cm, K= 0.064 year−1, t0=−3.2 years. The majority of the catch (67.4-90.1%, averaged 80.0%) belonged to 9-13 years old. The biomass had a descending trend from 4983.5 mt in 1990-91 declined to 10.6 mt in 2011-12. The generation length was 16 years. Stock status
This is just the beginning of many analyses on what the coelacanth can teach us about the emergence of land vertebrates, including humans, and, combined with modern empirical approaches, can lend insights into the mechanisms that have contributed to major evolutionary innovations, says Dr. Amemiya. The coelacanth is critical to study because it is one of only two living lobe-finned fish groups that represent deep and evolutionarily informative lineages with respect to the land vertebrates. The other is the lungfish, which has an enormous genome that currently makes it impractical to sequence. The lobe-finned fishes are genealogically placed in-between the ray-finned fishes (such as goldfish and guppies) and the tetrapods − the first four-limbed vertebrates and their descendants, including living and extinct amphibians, reptiles, birds and mammals. A lobe-finned ancestor(s) underwent genomic changes that accompanied the transition of life in an aquatic environment to life on land. The ...
The individual and combinational effects of probiotics on Persian sturgeon (Acipenser persicus) were evaluated through assessing the growth performance, proximate body composition, digestive enzymes and intestinal morphology. On the basis of feeding with experimental diets, the fish were assigned into four groups denoted as follows: control (basal diet), D‐Pro (basal diet + Bacillus subtilis and Bacillus licheniformis), D‐Pro/Yeast (basal diet + B. subtilis and B. licheniformis + Saccharomyces cerevisiae), Yeast (basal diet + S. cerevisiae). Maximum mean weight and length were measured for the fish fed with D‐pro regime. weight gain (WG), body weight gain (BWI%), feed efficiency (FE%), protein efficiency rate (PER), lipid efficiency rate (LER), and condition factor (CF) demonstrated the highest values for the fish fed with the diets containing D‐Pro and/or D‐Pro/yeast. LER and food conversion ratio (FCR) showed the highest performance for the fish received the D‐Pro diet. The diets ...

This fluid has presumably important functions for the offspring but so far its composition has not been characterised. In this study the proteome and peptidome of the cephalic secretion was studied in parental and non-parental fish using capillary electrophoresis coupled to mass spectrometry (CE-MS) and GeLC-MS/MS analyses. Multiple comparisons revealed 28 peptides were significantly different between males and parental males ...
The only Gulf of Maine fishes with which one might confuse an anchovy are young herring, smelt, or silversides, but it is easily distinguished from the former by the wide mouth, as just noted; by its much larger eye; by the relative positions of the fins with the dorsal wholly behind the ventrals instead of over them and with the latter originating close behind the tips of the pectorals when these are laid back against the body; and by its much longer anal fin. The lack of an adipose fin behind the dorsal is sufficient to separate anchovy from smelt at a glance, while the silversides (Menidia) have two dorsal fins instead of one. The anchovy has large, thin, easily detached scales and a deeply forked tail. This species may be distinguished from the striped anchovy by the fact that its anal fin originates under the front of the dorsal; by its more or less diffuse lateral band of silver; by its more numerous anal fin rays (24 to 27 contrasted with 20 or 21 for the striped anchovy), and by its ...

p> The Longfin Dragon Scale Mixed Colors Male Betta is an attractive variety of Betta splendens distinguished by its longer fins and Dragon Scales. More prominent in appearance, Dragon Scales are slightly larger in size than normal scales and have darker edges giving them an armored reptilian or mystical dragon-like appearance. The Longfin Dragon Scale Betta comes in an assortment of gorgeous color combinations with its breathtaking body coloration radiating into the fins in varying degree, making each individual a unique living piece of art.. The Longfin Dragon Scale Betta shares the same care requirements as other Betta splendens varieties. As such, only one male Betta should be kept in an aquarium. However, the smaller, shorter-finned females may be housed together with caution. If kept in a community aquarium, the Longfin Dragon Scale Betta should be housed with peaceful fish that will not nip at the Bettas glorious, flowing fins.. The ideal environment for the Longfin Dragon Scale ...

This entry discusses some marine life that can live with Betta. Regardless of the fact that the marine life mentioned in this post can handle life with a betta does not always mean that they will always be happy. There are several other factors, as mentioned below, so you should carefully observe both the betta fish and the sea life shown to see if they have bite indicators on them. A lot of new pet pets are that they are lonely. The Betts are very spatial and often want to be themselves. If the fish content is less than 5 gallons, it is likely to leave its own betta fish. They feel like any other fish in their place if the tank is too small. There are a number of items that you can tinker with other fish that can swim with a betta. The kind of betta, dignified, the size of the container and whether male or female are all important elements. Since betta fish is very territorial, one of the most important factors is how large the container is. Females are almost always less aggressive than ...

Native Fish and Amphibians From Fish Stocking SACRAMENTO, Calif.- The Sacramento Superior Court has ordered the California Department of Fish and Game into talks with Pacific Rivers Council and the Center for Biological Diversity to develop interim measures to limit harm to native species caused by fish stocking. The intent is to minimize the adverse effect that hatchery-raised fish inflict on sensitive native fish and amphibian species while the Department prepares an Environmental Impact Report under the California Environmental Quality Act.. Interim measures limiting stocking are needed to help save Californias native fish and frogs from extinction, said Noah Greenwald, biodiversity program director for the Center for Biological Diversity. Fish and Game should still be able to stock hatchery fish, but in places where they wont harm native species.. The court ruled in May 2007 that fish stocking has significant environmental impacts on aquatic ecosystems and in particular, on native ...

This study examined mechanisms underlying cardio-respiratory acclimation to moderate sustained hypoxia (6·0 kPa for 7 days at 22° C) in the bowfin Amia calva, a facultative air-breathing fish. This level of hypoxia is slightly below the critical oxygen tension (pcrit) of A. calva denied access to air (mean ± s.e. = 9·3 ± 1·0 kPa). Before exposure to sustained hypoxia, A. calva with access to air increased air-breathing frequency on exposure to acute progressive hypoxia while A. calva without access to air increased gill-breathing frequency. Exposure to sustained hypoxia increased the gill ventilation response to acute progressive hypoxia in A. calva without access to air, regardless of whether they had access to air or not during the sustained hypoxia. Additionally, there was a decrease in Hb-O2 binding affinity in these fish. This suggests that, in A. calva, acclimation to hypoxia elicits changes that increase oxygen delivery to the gas exchange surface for oxygen uptake and reduce ...
I used a conceptual model proposed by Schlosser (1987) to compare channelized and unchannelized reaches of the South Sulphur River, Texas. This model suggests that fish assemblage structure can be predicted based on the level of habitat heteroge neity, especially with regard to the level of pool development. Based on Schlossers model, I hypothesized that habitat heterogeneity would be greater in the unchannelized (as compared to channelized) reach of the South Sulphur River, which would therefore have more stable fish assemblages. Fish assemblages in this reach would have similar total fish density and higher species richness, in addition to lower density and higher biomass of larger-bodied fish (primarily piscivores and omnivores), as well as lower density and biomass of juveniles and adults of small-bodied species (primarily invertivores) as compared to the channelized reach. Habitat characteristics conformed to my predictions, but fish assemblage attributes were opposite those hypothesized. ...
This systematic review will address the need for a better understanding of the impacts of fish entrainment and impingement associated with hydroelectric dams on fish productivity in freshwater temperate environments. As the number of dams continues to increase worldwide, so too has concerns for their effects on fish populations. Fish injury and mortality at hydroelectric facilities may have serious consequences for fish populations, which are generally the result of three main sources: (1) fish passage through hydroelectric facilities (i.e., turbines, spillways, sluiceways, and other passage routes) during downstream migration for migratory fish; (2) the entrainment of resident fish; and (3) the impingement of fish (migratory or resident) against screens/trash racks. Most studies on the impacts of entrainment and impingement at hydroelectric facilities on fish have primarily focused on: (1) how fish injury and mortality occurs; and (2) evaluations of the effectiveness of various management strategies
FIFO cannot be directly related to the amount of wild fish that could be passed for human consumption, because it does not take into account whether the raw fish material comes from 1) fish that are eaten whole, such as sardines, 2) fish where half of the raw material (fillet) goes to human consumption, such as herring or 3) fish that are mainly not eaten by humans, such as sand eel. For feeds with a FIFO of 2, it would mean that in case 1), 2 kg of wild fish that could have been eaten by humans is used to produce 1 kg of salmon. In case 2), 1 kg of wild fish would be used, and in case 3) 0 kg of wild fish that could be used for human consumption would be used. Fishmeal and fish oil are also used as ingredients in animal feed in agriculture, and in food supplementation (capsules) for humans. EPA and DHA enriched eggs, milk and meat are produced by adding fish oil in the feed. ...

Background: The fish-tetrapod transition was one of the major events in vertebrate evolution and was enabled by many morphological changes. Although the transformation of paired fish fins into tetrapod limbs has been a major topic of study in recent years, both from paleontological and comparative developmental perspectives, the interest has focused almost exclusively on the distal part of the appendage and in particular the origin of digits. Relatively little attention has been paid to the transformation of the pelvic girdle from a small unipartite structure to a large tripartite weight-bearing structure, allowing tetrapods to rely mostly on their hindlimbs for locomotion. In order to understand how the ischium and the ilium evolved and how the acetabulum was reoriented during this transition, growth series of the Australian lungfish Neoceratodus forsteri and the Mexican axolotl Ambystoma mexicanum were cleared and stained for cartilage and bone and immunostained for skeletal muscles. In order ...

At present, culturists rely on the capture of wild juveniles to provide the seed as commercial scale methods for captive reproduction and early rearing have yet to be developed. Thus, there is a clear need to develop methods for breeding to preserve wild stocks and facilitate the selection of economically important traits. The latter requires genomic information such as the chromosomal locations of genetic polymorphisms and expressed genes. Currently, there are a limited number of yellowtail families available for linkage analysis. Even though a female linkage map with 180 microsatellite markers has been reported [2], there remains a need for maps of expressed sequence tags (ESTs) and cDNAs to inform yellowtail genomic ...
The European anchovy, Engraulis encrasicolus L. 1758, is one of the most sought-after target species in the northwestern Mediterranean Sea. However, this stock currently consists of small individuals, and landings are reported to have decreasedconsiderably. The main purpose of this study was to assess, for the first time, the interrelationships between size, fecundity, energy reserves and parasitism in female anchovies, in order to analyse the potential implications for the health of northwesternMediterranean anchovy stocks arising from the current shortage of large individuals. Results revealed that smaller individuals show lower fecundity, lower lipid content and a higher intensity of certain parasites. As it is known that smaller individuals now predominate in the population, the relationships found in this study indicate that the health of anchovies from the northwestern Mediterranean is currently ...
Ultrastructural analyses of fish-infecting myxosporean Henneguya piaractus that is found in the gill lamellae of the freshwater teleost Piaractus mesopotamicus (Characidae) and collected from the Paraguai River, Brazil were described. The parasite occurs within large whitish spherical to ellipsoidal polysporic cysts (up to 2.5 mm long) delimited by a layer of fibroblasts generally connected with some capillaries on the gill epithelium. No external morphological signs of disease were visible in the infected fishes. The tailed spores measured 61.5 ± 0.91 (60.2-62.6) μm in total length and ellipsoidal spore body 21.1 ± 0.62 (20.6-21.9) μm long, 6.7 ± 0.40 (6.2-7.3) μm wide and 2.5 ± 0.54 (2.0-3.1) μm thick. The spore wall was about 97 nm of thickness and consisted of a thin electron-dense exospore and a thick electron-lucent endospore with about 85 nm of thickness. The tailed spores were composed of two equal-sized shell valves adhering together along the straight suture line each having in ...
Bycatch of protected species in commercial fishing operations is a primary concern to fishery managers because it threatens the conservation, protection, and recovery of fragile species, such as the Atlantic sturgeon (Acipenser oxyrinchus oxyrinchus). One potential solution to reduce the risk associated with commercial fishing operations is to design commercial fishing gear that is more selective in terms of interactions between Atlantic sturgeon and commercial fisheries. Given this conservation and management need, the overarching goal was to reduce Atlantic sturgeon fishery interactions and maintain southern flounder (Paralichthys lethostigma) catch in North Carolina. The specific objectives of this study were to design and evaluate the effectiveness of a modified gillnet. Overall, the results proved that lowering the profile and amount of webbing had a beneficial impact at reducing Atlantic sturgeon incidental encounters and bycatch. The modified gillnet reduced bycatch and Atlantic sturgeon
Scientists studying fossil footprints may have followed fish where they thought they tracked tetrapods.. This morphological mix-up is suggested by a paper demonstrating walking behaviour in the African lungfish (Protopterus annectens).. Heather King, Neil Tiktaalik Shubin and their colleagues at the University of Chicago set out to confirm claims that this animal indeed walked on four legs. As you can see in the video below, they did. Using video evidence they report in the Proceedings of the National Academy of Sciences (PNAS) that lungfish use their pelvic fins to lift themselves off the bottom of rivers and streams and walk and even bound, despite lacking feet.. The reason this is important is the species is one of the few remaining members of the sarcopterygian class. Sarcopterygian fishes were the mothers and fathers of the animals that later became the four-legged land animals researchers call tetrapods.. The only other known sarcopterygian is the living fossil coelacanth, which ...
Atlantic cod (Gadus morhua L.), acclimated to 5 °C, were equipped with ultrasonic transmitters which allowed the continuous monitoring of their vertical movements and heart rate. Fish were then placed in a 125 m3 tower tank in which the various thermal conditions they encounter in their natural environment were reproduced. Physiological and behavioural responses of cod were followed in parallel to the induced environmental changes. The experimental conditions studied in the tower tank were also reproduced in a swimming respirometer, where oxygen consumption and heart rate could be monitored within the activity range of a free-swimming animal. In a homogeneous water column, a rise in temperature induced marked increases in fish swimming activity, heart rate and heart beat-to-beat variability. In a thermally stratified environment, voluntary activity also increased when the thermal structure of the water column was altered, though no temperature-dependent changes in heart rate were observed. ...
Triploidy in tambaqui Colossoma macropomum identified by chromosomes of fish larvae is an article from Journal of Aquaculture & Marine Biology for MedCrave Group. Triploid fish are excellent models for use in commercial scale because they can show higher rates of growth, carcass yield and meat quality. If sterile, tambaqui (Colosso mamacropomum) triploids can be used to avoid the problems related to early puberty, especially the negative impacts of male sexual maturation on harvest weight. In the present study, we evaluated the triploidy induction efficiency (thermal shocks) in the fish tambaqui Colossoma macropomum, the most important Neotropical species used for aquaculture. To verify the result of the triploidy experiments, we used a protocol of ploidy identification through analysis of mitotic chromosomes of early life stages (larvae cytogenetics). We obtained better results of hatching and triploid rates through temperature shock at 41°C for 2 min (heat shock) than cold shock. In conclusion,
The present study was undertaken to elicit the temporal sequence of changes in cardiovascular and respiratory function during aestivation. Twelve lungfish (2-6 kg) equipped with ECG electrodes, arterial and buccal cannulae, were studied while aestivating in mud or in artificial cloth-bag nests. The periods of observation ranged from 0.5 to 9.5 months. The mean arterial blood pressure gradually decreased from control values of 20-28 mm Hg to a range of 14-18 mmHg during the first 30 days of aestivation, whereas the heart rate dropped more gradually (22-30 beats/min to 11-16 beats/min in 6o days). Ventilatory frequency increased 2- to 5-fold during the first 30 days of encystment and then returned to the control range (2-10 h) within 45 days. The arterial PCOCO2 increased from control values of 25-30 mm Hg to 45-70 mmHg; arterial pH decreased concomitantly from 7.55-7.60 to 7.40-7.26 after the cocoon was formed. The arterial POO2 increased from the control range of 25-40 to 50-58 mmHg during the ...
Figure 3 - Phenogram of overall molecular similarity of RAPD bands among specimens from all localities at Tibagi, Paraná, and Iguaçu Rivers. Codes as in Figure 1. DISCUSSION The RAPD-PCR patterns indicate strong genetic differentiation within and among populations in the Paraná and the Tibagi Rivers. In the Paraná River at Porto Rico, the high levels of allelic polymorphism may represent the pristine composition of different species or populations within the H. malabaricus species complex, or they may be the outcome of faunal mixing caused by the closing of the Itaipu Dam in 1978 and the consequent flooding of Sete Quedas, another Oligocenic geographic barrier (Sampaio, 1988). Sete Quedas was the natural boundary for the Upper and Middle Paraná basins. The presence of an outlier in the Paraná River similar to the Iguaçu population suggests that the Paraná may indeed be a recipient of trahiras of diverse origins. The Londrina sample from the Tibagi River is most similar to the populations ...
TY - JOUR. T1 - The effects of pH and the iron redox state on iron uptake in the intestine of a marine teleost fish, gulf toadfish (Opsanus beta). AU - Cooper, C. A.. AU - Bury, N. R.. AU - Grosell, Martin. PY - 2006/3/1. Y1 - 2006/3/1. N2 - In the marine teleost intestine the secretion of bicarbonate increases pH of the lumen (pH 8.4 -9.0) and importantly reduces Ca2+ and Mg 2+ concentrations by the formation of insoluble divalent ion carbonates. The alkaline intestinal environment could potentially also cause essential metal carbonate formation reducing bioavailability. Iron accumulation was assessed in the Gulf toadfish (Opsanus beta) gut by mounting intestine segments in modified Ussing chambers fitted to a pH-stat titration system. This system titrates to maintain lumen pH constant and in the process prevents bicarbonate accumulation. The luminal saline pH was clamped to pH 5.5 or 7.0 to investigate the effect of proton concentrations on iron uptake. In addition, redox state was altered ...
The National Fish Consumption Day is one of the ways that the Namibia Fish Consumption Promotion Trust use to promote the consumption of fish and Otjozondjupa was chosen as the host of the National Fish Consumption Day 2014 at a gala dinner held in Gobabis last week Friday. Otjozondjupa was chosen last night to be the host of Fish Consumption Day 2014, we hope to reach more people, we hope for people to come out in numbers and support this day because the day is for the region and its people to become aware that consuming fish can assist people to maintain a healthy lifestyle, Albertina Ngurare, CEO of Namibia Fish Consumption Promotion Trust (NFCPT) told The Economist at the 2nd National Fish Consumption Day which was held at the Legare Stadium in Gobabis over the weekend. She said, although there is not a fish shop in that region yet, the Trust which has 13 fish shops in nine regions of the country plans to open one soon in Otjozondjupa. We do not have a fish shop yet in Otjozondjupa but it ...
A net energy gain (NEG) model was used to assess the effects of turbulence on the energy budget of Atlantic cod Gadus morhua larvae, feeding on copepod nauplii at different concentrations. The geometry of their prey search space was parameterised as either a sphere, hemisphere (the most commonly applied in analogous studies), or wedge. Observed distributions in behaviour (e.g. move duration, pause duration, turn angles) were used as model input, and 2 facets of this behaviour (move duration and move speed) were varied to examine how parameterised changes in foraging behaviour can affect the NEG of the predator. At a prey concentration of 100 l-1, and in static water, NEG is an order of magnitude higher for a hemispherical shape relative to a wedge-shaped search volume. This difference decreases with increasing prey concentration (600 l-1), but always remains considerable. When parameterised turbulence was added, prey capture rates for a larva with a hemispherical search space increases 3 times ...
The composition of the diet, the metabolic adaptations and variations in the activity of the fish are the main factors responsible for seasonal changes in physiological variables. It is known that aerobic exercise can improve the fish growth due to: the enhancement of feed conversion, reduced dominance, increased protein synthesis and lipid and glucose catabolism. The diet must satisfy the nutritional requirements of each species. Knowledge of the appropriate protein level is critical because maximizes feed conversion efficiency, lowers costs and reduces the load of nutrients released to the aquatic ecosystem. In Brazil, the pacu, Piaractus mesopotamicus, is an important fish in aquaculture, especially for hardiness, fast growth, excellent meat quality. This species may respond to exercise with lower levels of protein catabolism and for directing them to growth. Thus, a balanced diet and a well established aerobic exercise protocol could promote better growth for pacu. This study aimed to ...
Having a pet betta could bring happiness and entertainment to its owner. But sometimes we tend to neglect our pets and forget simple duties like cleaning their bowl. Betta fish diseases are easily avoided simply by properly maintaining the fish tank and providing it with the conditions that are closest to the conditions found in their natural environment. If you think that your fish is already sick, here are some examples of Betta fish diseases and their corresponding cures.. Ich (Ichthyophthirius multifilius). Ich, which usually manifests as small white dots around the mouth or the fins of a betta, is a protozoan parasite. A betta usually contracts this parasite when the temperature in the tank drops below 80 degrees for extended periods of time. To prevent ich from affecting your betta, you can raise the temperature of the water above 80 degrees Fahrenheit and add 3 teaspoons of salt per gallon of water in your tank. If your fish already has ich, medicines with methylene blue or malachite ...
A study of the coastal fish assemblages in the marine park of Ustica Island (Southern Tyrrhenian Sea, Mediterranean) was conducted from June 1994 to September 1995 and from June 1996 to September 1997. The principal aims of the research were to: (1) define the faunistic features of local fish communities; (2) assess the effectiveness of the protection regime of the marine park on the fish assemblages (reserve effect); (3) provide information on the distribution of some Epinephelus and Diplodusspecies in the shallowest depth zone of the island. During seasonal surveys, underwater visual censuses were carried out at several sites located in three zones of the island, each with a different level of protection. Observations were made along 250 m2 transects at 3-5, 10-15 and 25-30 m depth ranges. Additional surveys were made by SCUBA diving and snorkelling. A statistically significant effect of depth on the fish community parameters was observed, whereas differences linked to protection level, ...
Q.. Evolutionists often use as a proof of their theory the intriguing case of fish that live in deep-water caves and that have lost their sight permanently, yet still function quite well. Are blind cave fish a good example of organic evolution in action?. A.. Found in the subterranean caverns of the world are rare, unique, and sometimes exotic creatures. Numerous varieties of bats, spiders, insects, and other curious creatures populate these damp, cool environments. Hidden from the Sun, weather, and intrusion of man, these caverns represent a truly intriguing habitat. Another animal also dwells in these cavernous environments-the cave fish. Restricted to the dark confines of the globe, cave fish possess unique qualities that differ from the surface varieties generally seen. The most remarkable distinction between cave fish and their surface counterparts is a loss of visionary processes. There are several other interesting differences, but this particular disparity is the most commonly referenced ...

Evidence‐based decisions relating to effective marine protected areas as a means of conserving biodiversity require a detailed understanding of the species present. The Caribbean island nation of St Lucia is expanding its current marine protected area network by designating additional no‐take marine reserves on the west coast. However, information on the distribution of fish species is currently limited. This study used baited remote underwater stereo‐video to address this shortcoming by investigating the effects of depth and seabed habitat structure on demersal fish assemblages and comparing these assemblages between regions currently afforded different protection measures. From the 87 stations visited a total of 5,921 fish were observed comprising 120 fish taxa across 22 families. Species richness and total abundance were higher within the highly managed region, which included no‐take reserves. Redundancy analysis explained 17% of the total variance in fish distribution, driven ...

Researchers have revealed that the African lungfish can use its thin pelvic limbs to propel itself forward.. The teams discovery reshuffles the order of evolutionary events leading up to creatures being able to walk, and also suggests that fossil tracks long thought to be the work of early tetrapods could have been produced instead by lobe-finned ancestors of the lungfish.. In a number of these trackways, the animals alternate their limbs, which suggested that they must have been made by tetrapods walking on a solid substrate, Melina Hale, PhD, associate professor of Organismal Biology and Anatomy at the University of Chicago Medical Center, said in a press release Weve found that aquatic animals with fundamentally different morphologies and that arent tetrapods could potentially make very similar track patterns.. Lungfish are a popular pet in the paleontological community and have a unique evolutionary heritage.. The lungfish is in a really great and unique position in terms of how it ...
The problem for saltwater fish is more or less the exact opposite as freshwater fish, and it should come as no surprise then that their drinking and urinating habits likewise go the other way. The saltwater fish have less salt in their blood than the surrounding water (hypotonic). So rather than absorbing water as it passes through their gills, saltwater fish lose a lot of water from their blood as they breathe via the same osmotic pressure as mentioned with the freshwater fish. As a result, they must drink considerable amounts of water through their mouths. However, again, because the part of the brain that controls this is in the hindbrain, its generally thought this regular swallowing of water is a reflex action performed without a conscious thirst sensation.. Saltwater fish also dont urinate much at all, in order to conserve water. Towards this end, they have very few, small capillary networks making up their glomerulus, unlike freshwater fish.. However, the water the saltwater fish are ...
Freshwater tropical ornamental fish culture is the largest component of aquaculture in the State of Florida and accounts for approximately 95% of all ornamentals produced in the US. There are about 200 Florida producers who collectively raise over 800 varieties of freshwater fishes. In 2003 alone, farm-gate value of Florida-raised tropical fish was about US$47.2 million. Given the additional economic effects of tropical fish trade such as support industries, wholesalers, retail pet stores, and aquarium product manufacturing, the importance to Florida is tremendous.. Floridas tropical ornamental aquaculture industry is concentrated in Hillsborough, Polk, and Miami-Dade counties with additional farms throughout the southern half of the state. Historic factors, warm climate, the proximity to airports and other infrastructural considerations (ready access to aquaculture equipment, supplies, feed, etc.) are the major reasons for this distribution. Having other farms nearby is advantageous because ...

The production of Atlantic cod (Gadus morhua L.) in aquaculture continues to be hindered by large losses during juvenile production. These losses are often the result of the bacterial disease vibriosis, caused by the marine pathogen Vibrio anguillarum. The preventative vaccination of Atlantic cod against this pathogen has become standard practice in order to decrease the frequency of disease outbreaks. While vaccination by intra-peritoneal injection and bath immersion are consistently effective at preventing pathogen invasion through the skin and gills, neither of these methods fully protect the mucosal surfaces of the intestinal tract, which is an important site of immune response in many teleost species. The oral delivery of vaccines in feed pellets could provide a cheaper, easier method of vaccine delivery; however, this method is currently not effective enough for large-scale use, due to the degradation of vaccine antigens in the acidic environment of the fishs stomach. Juvenile Atlantic cod were

In todays society, one often stumbles over the quote you are what you eat. Diet is closely related to fish size and physical conditions, so in order to understand the food web one must first understand the population dynamics of the fish. Three demersal species in the northern hemisphere are; Artediellus atlanticus, Myoxocephalus scorpius and Leptagonus decagonus. The study was undertaken in 2009-2011, within the inner basin of Porsangerfjord (70oN 25oE) through the project Ecological Processes and Impacts Governing the Resilience and Alternations in the Porsangerfjord and Hardangerfjord. The study objectives were to provide basic information about these species population dynamics and feeding ecology. The length distribution varied between both sex and species, whereas the age structure was the same. The growth were different for L. decagonus but not for A. atlanticus and M. scorpius. The dominant prey found in A. atlanticus was Polychaeta, whereas M. scorpius fed on fish, and L. decagonus ...
Viral diseases in fish Most serious fish diseases are caused by viruses. We are therefore primarily concerned with viral fish diseases, and especially with viruses within the rhabdoviridae family (VHSV, IHNV, Perch RV, SVCV, and others), but also within the alloherpesviridae (CyHV1-3, AnHV-1), birnaviridae (IPNV), orthomyxoviridae (ISAV), and iridoviridae (EHNV and ranavirus) families.. In addition, we maintain contingency on viruses within the alphaviridae, nodaviridae and reoviridae families. The Fish Diseases Group is primarily built around our international cutting edge research on viral haemorrhagic septicaemia (VHS) - a disease that is widespread in the northern hemisphere and causes significant losses for the fish farming industry.. Focus on diagnostics The main focus of our research is the host-pathogen interactions in fish, where we cover the entire area from molecule to fish and herds. In addition, we have many assignments in terms of development and validation of diagnostic methods ...
Velvet is another fish disease caused by parasites. It resembles the symptoms of ICH but the white spots on the fishs body will look like dust and will be tinier. The spots might also appear gold or gray in color. Because of their small size, the spots may be difficult to see, so you will have to observe the fish carefully. You will notice that, as with ICH, the fish will rub against objects, show difficulty in breathing or gasp for air near the surface of the tank if the gills have been affected. Most veterinarians recommend using the same copper medication treatment used for ICH.. Your fish may also develop a fungal infection/disease. This will appears as a white or gray color on the body of the fish. The fungus usually appears on the fins or mouth of the fish. Sometimes this disease can be induced by injury from another fish in the tank. Some fish attack other fish with their fins, leaving wounds that are prone to fungal infections. You can purchase medication just for fungal from your local ...

Fish Consumption and Ischemic stroke in Southern Sweden - Nutr J. 2011 Oct 11;10(1):109 - Stroke risk decreased with fat fish intake ([greater than or equal to] 1/week versus ,1/month) in both men and women; adjusted pooled Odds Ratio (OR) 0.69, 95% Confidence Interval (CI): 0.54-0.89. However, stroke risk for women increased with intake of lean fish; adjusted OR 1.63 (95% CI: 1.17-2.28), whereas there was no association with mens lean fish intake; adjusted OR 0.97(95% CI: 0.73-1.27). Fish intake was self-reported retrospectively, yielding uncertain exposure assessment and potential recall bias. The findings regarding lean fish would be explained by recall bias if an individuals inclination to report lean fish consumption depended on both disease status and sex. The fact that the association between fat fish intake and stroke was similar in men and women does not support such a differential in recall ... The results suggest fat fish intake to decrease ischemic stroke risk and lean fish intake ...

d it is an important nutrient for fetal and childhood development. However, fish can accumulate toxins such as Mercury and Polychlorinated Biphenyls (PCBs) in their tissues from the water they live in and through their diets. This can cause harmful effects to humans eating the fish.. The Indiana State Department of Health, working together with Indiana Departments of Environmental Management and Natural Resources, produce fish consumption recommendations for Indiana public waters to avoid high levels of toxins from consuming fish. The Indiana Department of Environmental Management includes the Fish Tissue Contaminants Monitoring Program, to assess the levels of bioaccumulation from pollutants in fish from Indiana waterways. The information collected provides the basis for determining the advisories for each location..

ZAMBIA - The Zambian government has announced the start of a fish farming project aimed at boosting the production of fish for both local consumption and export.. The Aquaculture Productivity and Market Enhancement project aims at achieving the target of producing 50,000 tons of fish per year in two years.. Minister of Fisheries and Livestock Michael Katambo said the African Development Bank (AfDB) has pumped US$50 million into the project.. Apart from producing fish for local consumption, the project will help the country produce surplus fish for export, he added.. According to him, the high demand for fish in neighboring countries such as the Democratic Republic of Congo as well as the international market provides an opportunity for the country to boost fish production.. The project targets small and medium enterprises who will be given loans to start fish farming projects.. It will support construction of fish ponds, production of fingerlings in three of the countrys provinces.. The ...
