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 ...
The freshwater fish louse Dolops carvalhoi is an ectoparasite of pacu, Piaractus mesopotamicus capable of causing substantial damage to its hosts. The aim of this study was to investigate some aspects of the host-parasite interaction between these two species. For this purpose the physiological and morphological responses and the participation of the non-adaptive immune system of pacu to the experimental infestation with D. carvalhoi were analyzed. Three different experimental protocols were designed in order to find out the effects of the parasites on their hosts, the host responses that may interfere with parasite establishment and the influence of chronic exposure of hosts with juvenile D. carvalhoi to a second acute stressor of confinement. The results showed that even low level of adult parasite infestation is capable to induce a stress response in the hosts. No changes were observed regarding the plasma osmoregulatory parameters, while an increased number of gill chloride cells and ...

Discussion. Astyanax is a highly diverse and taxonomically complex genus and its taxonomy and relationships seems to be far from a reasonable understanding. The diagnostic combination of characters proposed by Eigenmann (1921, 1927) to distinguish Astyanax from other genera of the Characidae is very variable and presents great overlap. These problems are more evident distinguishing Astyanax from Hemigrammus Gill, Bryconamericus Eigenmann, Moenkhausia Eigenmann, and Hyphessobrycon Durbin. As a practical example, according to Eigenmann (1921, 1927) Astyanax is distinguished from Bryconamericus mainly by the presence of five inner premaxillary teeth (vs. four teeth) and reduced size of the third infraorbital bone, which is not in contact with the preopercle (vs. expanded third infraorbital in contact with preopercle). Nevertheless, these characters are not exclusive from Astyanax and are widely distributed and variable among characid genera.. Malabarba & Weitzman (2003) hypothesized a monophyletc ...

SummaryWeight gain, length, and survival of Pacu (Piaractus brachypomus) larvae were analyzed after they were fed one of four diets. At 36 hours post-hatching larvae were fed for the first time and during three consecutive days: Artemia salinanauplii (T1), wild plankton filtered to 200 microns (T2),concentrated powder with 48% crude protein (T3) or no diet (fasting, T4). Animals were kept at a density of 70 larvae per liter. Statistically significant differences were observed with respect to the final weight for T1, T2, T3, and T4 (2.2 ± 0.3a, 1.7 ± 0.3b, 1.5 ± 0.3bc, 1.5 ± 0.2c mg, respectively) , final length (6.37 ± 0.29a, 0.20b ± 6.16, 5.95 ± 0.27c, 0.26c ± 5.87 mm, respectively), weight gain (0.77 ±0.39a, 0.31b ± 0.34, 0.16 ± 0.37bc, 0.08 ± 0.21 c mg, respectively) and length gain (0.39 ± 0.17A, 0.18± 0.15b, 0.16c ± -0023, -0102 ± 0.15c mm, respectively). The T1 diet had the best results for optimal growth, followed by T2. The survival rate was not statistically different ...
The Piranha Unmanned Surface Vessel (USV or unmanned surface vehicle) is a watercraft developed by Zyvex Marine (a division of Zyvex Technologies, formerly Zyvex Performance Materials) in 2010. The boat is 54 in length and weighs just 8,000 lbs. The Piranha is the first USV to utilize a lightweight carbon-nanotube enhanced composite material called Arovex, which allows the watercraft to weigh "significantly less" than any other USV. The weight advantage from Arovex gives the Piranha a payload capacity of 15,000 lbs and a range of over 2,500 miles. Additionally, the carbon-nanotubes actually provide a strength increase of 20-50% over traditional materials. With those characteristics, the Piranha is expected to be sold as a possible tool for anti-piracy, search and rescue, submarine hunting, and harbor patrol. The first Piranha began construction in February 2010 with an anticipated completion date of summer 2010. The Piranha underwent sea trials near Seattles Puget Sound during the months of ...
Nitrogen metabolism in tambaqui (Colossoma macropomum), a neotropical model teleost: hypoxia, temperature, exercise, feeding, fasting, and high environmental ammonia.. PubMed. Wood, Chris M; de Souza Netto, José Gadelha; Wilson, Jonathan M; Duarte, Rafael M; Val, Adalberto Luis. 2017-01-01. The total rate of N-waste excretion (M N) in juvenile tambaqui living in ion-poor Amazonian water comprised 85 % ammonia-N (M Amm-N) and 15 % urea-N (M Urea-N). Both occurred mainly across the gills with only ~5 % of M Amm-N and ~39 % of M Urea-N via the urine. Tambaqui were not especially tolerant to high environmental ammonia (HEA), despite their great resistance to other environmental factors. Nevertheless, they were able to maintain a continued elevation of M Amm-N during and after 48-h exposure to 2.5 mmol L(-1) HEA. The normally negative transepithelial potential (-18 mV) increased to -9 mV during the HEA period, which would help to reduce branchial NH4(+) entry. During 3 h of acute environmental ...
The ecotoxicology of nano-TiO2 has been extensively studied in recent years; however, few toxicological investigations have considered the photocatalytic properties of the substance, which can increase its toxicity to aquatic biota. The aim of this work was to evaluate the effects on fish exposed to different nano-TiO2 concentrations and illumination conditions. The interaction of these variables was investigated by observing the survival of the organisms, together with biomarkers of biochemical and genetic alterations. Fish (Piaractus mesopotamicus) were exposed for 96 h to 0, I, 10, and 100 mg/L of nano-TiO2, under visible light, and visible light with ultraviolet (UV) light (22.47 J/cm(2)/h). The following biomarkers of oxidative stress were monitored in the liver: concentrations of lipid hydroperoxide and carbonylated protein, and specific activities of superoxide dismutase, catalase, and glutathione S-transferase. Other biomarkers of physiological function were also studied: the specific ...
The eyeless cavefish Astyanas mexicanus is "a special system in which we can look at evolution in action," says article co-author William Jeffery, a senior adjunct scientist at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., and a professor at the University of Maryland. The Science study was led by Nicolas Rohner and Clifford J. Tabin at Harvard Medical Schools Department of Genetics.. Using the cavefish, the team demonstrated for the first time in nature how "standing" or "cryptic" genetic variations in an animal, which have been inherited from prior generations without causing any physical changes in the animal, can be "unmasked" by the shock of entering a new environment. Gene variants that improve the animals ability to adapt to that new environment can then be selected for, and passed on to its progeny. This is distinct from the established evolutionary mechanism of "de novo" genetic mutations that arise by chance after the animal has entered the new environment, which also ...

Of course, if Dr. Wieland had bothered to read the actual article (rather than merely the press reports that creationists are so fond of) he would have found that Astayanax mexicanus "evolved from eyed, surface-dwelling forms which only reached the area in the mid-Pleistocene," that is, between 600,000 to 1 million years ago. How does Borowsky know this? This is where references matter. Earlier research by Ulrike Strecker and colleagues, published in Molecular Phylogenetics and Evolution (subscription required) showed that mutations occur in freshwater fish at a rate of 1.5% per million years. By analyzing the differences in cytochrome b genes between currently living species and then dating the nearest common ancestor of each in the fossil record, Strecher et al. proposed that Astyanax first arrived in the Yucatan no earlier than 900,000 years ago, just as Borowsky states. How can Wieland be so certain that "it would not take long at all" for such mutations to occur? Not presenting any evidence ...

Theres no denying that James Cameron is a talented man in this industry and he has made a few of the greatest innovations in recent years (notably further exploring the Titanic and the current 3D technology.) Though his script writing talents are questionable and aspects of his directing are suspect Cameron seems to have an uncanny ability to pull great work from his actors, but his biggest talent may not be as a director. Cameron is likely one of the greatest cinematographers thats not working as one. With all due respect to the cinematographers whove worked with him (though there are numerous rumors that speak to Cameron being extremely difficult to work with) his films all have a stunning beauty that remains constant though his director of photography may not. "Piranha Part 2: The Spawning" may not be a grand sprawling epic that Cameron will become known for but inklings of that talent are evident to the keen observer.

Heres how I look at it: if an animal lives in an environment in which change is infrequent and today can be expected to be a repeat of yesterday, then it makes sense for its way of life to evolve into a set of structured, repeated patterns triggered by familiar environmental stimuli. It saves a lot of energy, since there is no need to develop the neural complexity required to deal with change; energy is also saved in the day-to-day activities of life because theres less information processing to be done, and less physical hesitation and vacillation also. And in fact, most animal behaviour is of precisely this kind. Animals are mostly automatons ...

The Mexican tetra, Astyanax mexicanus, is a unique model system consisting of cave-adapted and surface-dwelling morphotypes which diverged ,1My ago. This remarkable natural experiment has enabled powerful genetic analyses of cave adaptation. Here, we describe the application of next-generation sequencing technology to the creation of a high-density linkage map. Our map comprises over 2200 markers populating 25 linkage groups constructed from genotypic data generated from a single genotyping-by-sequencing project. We leveraged emergent genomic and transcriptomic resources to anchor hundreds of anonymous Astyanax markers to the genome of the zebrafish (Danio rerio), the most closely related model organism to our study species. This facilitated the identification of 784 distinct connections between our linkage map and the Danio rerio genome, highlighting several regions of conserved genomic architecture between the two species despite ~150My of divergence. Using a Mendelian cave-associated trait as ...
There were significant within-treatment differences (ANOVA) for both cyclophosphamide (F = 8.38; P £ 0.05) and vinblastine sulfate (F = 8.54; P £ 0.05), and also when compared with their respective control group. The Student-Newman-Keuls test indicated that the cyclophosphamide doses of 4 and 32 mg/kg body weight did not alter the frequency of MN compared to the control, whereas the other doses (8 and 16 mg/kg body weight) significantly increased the frequency of MN. The frequencies of MN for cyclophosphamide concentrations of 8 and 32 mg/kg body weight were similar and did not differ significantly to the values observed with the dose of 4 mg/kg body weight. Likewise, the responses to 8 and 16 mg/kg body weight were also similar. There were no significant differences in the frequency of MN among the different doses of vinblastine sulfate used. However, the MN frequencies with all of the doses were significantly higher than in the control group. DISCUSSION Cytogenetic methods are probably the ...

The fish species Astyanax mexicanus exists in a form that exists above ground and has normal eyes and in forms that exist in caves (cavefish), which are blind and undergo degeneration of the eye. In evolutionary terms, the loss of the eye might simply reflect lack of selection for eyesight in cavefish. However, Yamamoto et al. present evidence that, instead, eye degeneration appears to have been derived as an adaptive trait driven by natural selection. Critical signals for eye development come from the cells of the anterior embryonic midline in the form of so-called hedgehog (Hh) proteins. In cavefish, eye primordia form but stop developing and degenerate. This phenotype appears to arise not from failure of Hh signaling, but rather from increased expression of Hh proteins in the developing cavefish embryo. Increased Hh signaling in wild-type embryos (induced by injection of mRNA encoding Hh proteins) produced adults that lacked an eye. Application of a pharmacological inhibitor of Hh signaling ...

Assim, com o presente estudo objetivou-se avaliar os efeitos do óleo de orégano sobre o desempenho produtivo, reservas energéticas e ...
Evolution maintains that as more time passes, living things evolve to acquire better and more useful traits. As such, shouldnt the loss of a useful trait, such as eyesight, be regarded as the opposite of evolution? Not so, say recent news reports on blind fish.. Biologists compared DNA sequences from 11 populations of cavefish (Astyanax mexicanus), which are a blind variation of the Mexican tetra fish, to 10 related fish populations that have the ability to see. Since they can interbreed, they are the same species.1. A New York University news release attributed the fishes loss of sight to convergent evolution, which makes little sense if evolution, as neo-Darwinists describe it, is supposed to generate new features and functions.. The blind fish do not trace their lineage to just one blind ancestor. In fact, the study authors wrote in BMC Evolutionary Biology, The results also demonstrate that cave populations in the region studied arose at least five times independently and derive from ...
Concrete foundations in the campground and picnic areas of the park are remnants of a transient work camp built there in 1934 by the State. The camp provided work and lodging for men displaced during the Depression years. In addition to building trails, logging, and completing public service projects, these men helped fight a fire in 1935 that burned more than 10,000 acres in the area. Later the men set up a sawmill and began to salvage fire-damaged wood.. In 1957, a 940-acre parcel of forest along the Brule River was set aside as Brule River State Park. The park became Judge C. R. Magney State Park in 1963 when the Minnesota legislature selected this park as a memorial to the late Judge Magney, a lawyer, mayor of Duluth, justice of the Minnesota Supreme Court, and a strong advocate of Minnesota State Parks, especially those along the North Shore. With his influence, he was instrumental in establishing 11 state parks and waysides along Lake Superior. Over the years, parcels of land have been ...
Abstract Aside from Madtsoiidae, anilioids, and Boidae that were studied previously, the middle Palaeocene of ltaborai (BraziI) has produced Ungaliophiinae ("tropidophiids"), booid-grade snakes incertae sedis, and a possible Russellophiidae (Caenophidia) that are described in the present article. This article is the third and final report on the snakes from the locality. The Ungaliophiinae (Paraungaliophis pricei gen. et sp. nov.) are rare whereas the booid-grade snakes incertae sedis (ltaboraiophis depressus gen. et sp. nov., Paulacoutophis perplexus gen. et sp. nov.) are more frequent. A single vertebra is referred to the Russellophiidae (Caenophidia) with reservation. An update of the whole fauna of snakes from ltaborai is provided. Hechtophis austrinus that was tentatively referred to the erycine Boidae is now regarded as a Boidae incertae sedis. Most snakes from Itaborai are known only from the locality. Astonishingly, only the ailioids Coniophis cf. C. precedens gives possible evidence of ...

Balbina Reservoir in Brazil has large numbers of black piranha, the largest piranha species. Find out from Jeremy Wade what you need to hook these.
The popular image of red-bellied piranhas portrays them as more feared than fearful. However, the results of our investigation are consistent with an anti-predator function for shoaling in the species. We found that opercular rate, which typically increases under risk (Metcalfe et al. 1987; Barreto et al. 2003), and may be indicative of a fishs preparedness to flee (Hawkins et al. 2004), was lower in larger groups, even in the absence of an overt predation threat. Furthermore, after a simulated attack, opercular rate remained elevated for longer in the smaller shoals. Because the size of red-bellied piranha shoals at Mamirauá ranges from fewer than 10 to about 100 (H. Queiroz and A. E. Magurran, personal observation), the grouping advantages detected in this experiment are applicable to fishes in the wild. Our study not only casts new light on the behaviour of a charismatic, though poorly researched species, but also reveals how a fishs perception of risk is affected by shoal size.. In the ...

Meramec State Park is a state-owned, public recreation area located near Sullivan, Missouri, about 60 miles from St. Louis, along the Meramec River. The park has diverse ecosystems such as hardwood forests and glades. There are over 40 caves located throughout the park, the geology of which is a mixture of limestone and dolomite. The most famous is Fisher Cave, located near the campgrounds. The park borders the Meramec Conservation Area. The park was acquired by the state in 1927, then saw active development by the Civilian Conservation Corps (CCC) between 1933 and 1935. At that time, trails were laid out and numerous buildings constructed including a dining hall, recreation hall, concession building, and shelters. Three surviving CCC-era structures were added to the National Register of Historic Places in 1985: the Meramec State Park Lookout House/Observation Tower, the Meramec State Park Pump House, and the Meramec State Park Shelter House. In 1991, the Meramec State Park Beach Area Historic ...

Astyanax fasciatus B23 protein: a blue visual pigment protein; expressed in the retina of fish, Astyanax fasciatus; has high homology to the goldfish blue visual pigment; do not confuse with nucleolar protein B23, a phosphoprotein; aa sequence given in first source
Cave animals have adapted to the challenges of life in perpetual darkness by losing their eyes and pigmentation and enhancing other sensory systems, such as taste, smell, and tactile senses. Although the sensory gains are easily explained by natural selection, the losses are more difficult to explain because they seem to have no immediate benefits. Recent studies in the Mexican cavefish (Astyanax mexicanus) show that eye degeneration is developmentally linked to adaptive gains in the gustatory system via evolutionary changes in a pleiotropic gene called sonic hedgehog. Thus, cavefish may illustrate a general phenomenon in biology in which pleiotropy and indirect selection guide the course and extent of evolution. Another benefit for cavefish living in dark caves is the absence of predators, which promotes survival by evolving an unusual suite of feeding behaviors. These behaviors would be risky in more complex, well-lit environments, such as exist on the Earths surface, illustrating the ...

Hypothesizing that the Amazonian water system differences would affect the expression of muscle growth-related genes in juvenile tambaqui |i|Colossoma macropomum|/i| (Cuvier 1818), this study aimed to analyze the morphometric data and expression of myogenic regulatory factors (MRFs) in the white and red muscle from tambaqui obtained from clear and black Amazonian water systems. All of the MRF transcript levels (|i|myod|/i|, |i|myf5|/i|, |i|myogenin|/i|, and |i|mrf4|/i|) were significantly lower in the red muscle from black water fish in comparison to clear water fish. However, in white muscle, only the |i|myod|/i| transcript level was significantly decreased in the black water tambaqui. The changes in MRFs gene expression in muscle fibers of tambaqui from black water system provide relevant information about the environmental influence as that of water systems on gene expression of muscle growth related genes in the |i|C. macropomum|/i|. Our results showed that the physical and chemical water

Well-documented introductions provide a valuable opportunity to examine how founder events influence genetic diversity in invasive species. House finches (Carpodacus mexicanus) are passerine birds native to western North America, with the large eastern North American population derived from a small number of captive individuals released in the 1940s. Previous comparisons using amplified fragment length polymorphism (AFLP) markers found equivalent levels of diversity in eastern and western populations, suggesting that any genetic effects of the founder event were ameliorated by the rapid growth of the newly established population. We used an alternative marker system, 10 highly polymorphic microsatellites, to compare levels of genetic diversity between four native and five introduced house finch populations. In contrast to the AFLP comparisons, we found significantly lower ...
Aphanomyces were initially known as parasites of plants, small invertebrates and crustaceans. Probably the first case reported of fish being infected by Aphanomyces species was from guppy (Poecilia reticulata), Maxican blind cave (Astyanax mexicanus), a hybrid of platy (Platypoecilus maculatus) and swordtail (Xiphophorus hellerii) [26]. Aphanomyces, along with other oomycetes, e.g. Saprolegnia species have caused severe losses to aquaculture industry till to-date. From an evolutionary point of view it seems that the pathogenesis of plant oomycetes is mediated by effectors, while host invasion by animal pathogenic oomycetes is facilitated by expansion of proteases [24]. Many infectious microorganisms require proteases for replication or use proteases as virulence factors to cross proteinaceous barrier within the host. Proteases secreted by the fish oomycete Saprolegnia parasitica are suggested to be involved in attacking the host tissue and paving the way for further penetration of the fungus ...
Respiratory burst activity during stimulation of alveolar macrophages was studied in-vitro. The purpose of the study was to test the assumption that oxygen consumption stimulated by exposing alveolar macrophages to xenobiotics was used in releasing superoxide- anion (O2-). Suspensions of alveolar macrophages obtained from male Sprague-Dawley-rats were stimulated with 0 to 3000 micrograms per milli
FIELD LOCATIONS AND CONDITIONS Field testing of the CamelBak Antidote reservoir took place in the forested terrain of the Appalachian Mountains including Herrington Manor State Park, Potomac-Garrett State Forest, Fork Run Recreation Area and Swallow Falls State Park in Maryland, and the Canaan Valley Institute National Recreation Trails, Blackwater Falls State Park, Coopers Rock State Park and the Canaan Mountain, Roaring Plains West Wilderness and Dolly Sods areas of the Monongahela National Forest in West Virginia. Elevations ranged from around 2500 to 4800 ft (762 to 1463 m). The Antidote was used during 8 dayhikes totaling 55 miles (89 km), 12 mountain bike rides totaling 111 miles (179 km), 10 cross country ski trips of about 1 to 2 hours duration each and once while kayaking on a lake. Testing occurred under a wide range of temperatures and conditions ranging from early fall mountain bike rides during sunny 70 to 75 F (21 to 24 C) days to cold blustery skiing at temperatures as low as 11 F ...
To investigate the molecular mechanism and evolution of red-green color vision, we cloned, sequenced and expressed in vitro the red-green sensitive type pigment genes of 8 mammals, goat ( Capra hircus ), rabbit ( Oryctolagus cuniculus ), rat ( Rattus norvegicus ), cat ( Felis catus ), horse ( Equus caballus ), deer ( Odocoileus virginianus ), guinea pig ( Cavia porcellus ) and squirrel ( Sciurus carolinensis ), and the goldfish ( Carassius auratus ). Additionaly, red-green pigments of three more vertebrates, chicken ( Gallus gallus ), frog ( Xenopus laevis ) and cave fish ( Astyanax mexicanus ), that previously had been isolated by other investigators, were expressed in vitro. The absorption spectra of the purified goat, rabbit, rat, cat, horse, deer, guinea pig, squirrel, chicken, frog, cave fish red, cave fish green and goldfish pigments had wavelengths of maximal absorption (λ max ) of 553 ± 1, 509 ± 1, 509 ± 1, 553± 1, 545 ± 1, 531 ± 1, 516 ± 1, 532 ± 1, 561 ± 2, 558 ± 2, 559 ± 2, 530 ±

The authors note that "During the same period, more sophisticated types of fishing gear, most importantly nylon gill and seine nets, were introduced into the area. In addition, with the growing local and export market for fish products, ice plants were opened to help in the preservation of fish for long distance shipment… [and] large-capacity motorized fishing vessels were also introduced." The result, a significant increase in the productivity of the fisheries. However, this gain was short-lived. The authors conclude that "though there is apparently no evidence that heavily exploited fish species are in danger of extinction over the region as a whole, local depletion of commercially important species has become a problem and the productivity of fisheries in the Amazon has dropped significantly after an initial boom during the late 1960s and early 1970s.". The expansion of commercial fishing activities may have also affected the catch by subsistence or artisanal fishermen among the local ...

The plants Brosimum gaudichaudii (inharé) and Caesalpinia ferrea (jucá) are widely distributed throughout Brazil and are considered medicinal. Inharé has been popularly used as a blood purifier, for the treatment of skin and vitiligo, while jucáis considered analgesic, anti-inflammatory and anticancer. These therapeutic properties have been attributed to phytochemicals such as coumarins, flavonoids and tannins. However, the mechanisms of action of most of these phytochemicals have not yet been fully elucidated and they may compromise human health. Consequently, the evaluation of the genotoxic effect of these plant extracts is fundamental for the determination of safe doses for human consumption. We evaluated the genotoxic effect of various concentrations of extracts of B. gaudichaudii and C. ferrea using comet assay of erythrocytes from Astyanax sp. exposed in vivo. In the comet assay indicated the tail migration of DNA increased significantly in the group of cells exposed to C. ferrea for ...
