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 ...

The African lungfishes are the genus Protopterus and constitute the four species of lungfish found in Africa. Protopterus is the sole genus in the family Protopteridae. African lungfishes are elongated, eel-like fishes, with thread-like pectoral and pelvic fins. They have soft scales, and the dorsal and tail fins are fused into a single structure. They can either swim like eels, or crawl along the bottom, using their pectoral and pelvic fins. The largest species reach about 200 cm (6.6 ft) long. African lungfishes generally inhabit shallow waters, such as swamps and marshes; however, they are also found in larger lakes such as Lake Victoria. They can live out of water for many months in burrows of hardened mud beneath a dried-up stream bed. They are carnivorous, eating crustaceans, aquatic insect larvae, and molluscs. The African lungfish is an example of how the evolutionary transition from breathing water to breathing air can happen. Lungfish are periodically exposed to water with low oxygen ...

Identification and characterisation of thirteen new microsatellites for Atlantic cod (Gadus morhua L.) from a repeat-enriched ...

The genus Seriola, which includes yellowtail (Seriola quinqueradiata), amberjack (Seriola dumerili), and kingfish (Seriola lalandi), accounted for ,60% of the total Japanese mariculture production in 2011 [1]. Yellowtail, in particular, are very popular with Japanese consumers. 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 ...

Koi Fish Tattoo: Butterfly Fish Tattoos on a Blue Turtle (Fishermans Tuna)Fish Taco Sauce: Butterfly fish tattoos on a Yellow Turtle (Muskie Fish)Fishing in the Sun: Butterfly Turtle Tattoos (Fishers Tuna - Turtle & Bass - Bass)In a sea of tropical fish and other tropical fish species, I think the butterfly fish tattoo is a unique and unique addition to the collection.. I have a personal favorite for its uniqueness, however, it is not the only fish tattoo on my body.. Fishing at the Sunfish & Bass Museum in South Carolina has had a long history, dating back to the early days of the sport. The fish that was at the time the most popular fish, the Atlantic cod, was considered a delicacy and a fish that could be enjoyed for a very long time, so it was important that you have a fish tattoo that would be seen by many people and that would remain with you, said Jeff Gorman, an associate curator of the museum.. Gorman and the museums other curators, Dr. Charles Buehler and Dr. Michael DeMarco, both ...

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 ...

Home , Setting up ornamental fish bowl , Setting up of ornamental White Cloud Mountain minnow fish bowl. White Cloud Mountain minnow can be reared in ornamental fish bowls. This ornamental fish is known in the aquarium trade in various names like White Cloud minnow, Chinese danio and White Cloud Mountain fish.. These species of minnows are native to China and are first discovered in White Cloud Mountains. These mountain minnow are very hardy and tolerate fluctuations of temperature, pH and water hardness. They can stand low temperatures and usually do not require heaters.. There are two main variants of this pet namely meteor and white cloud golden. Other variants like blond, pink and golden meteor have resulted due to breeding techniques.. These breed easily scattering their eggs among the plants and substrates in the ornamental bowl. The breeders may be given worms for good results. The eggs hatch after two days and the babies are fed with feed powder and infusoria.. The babies can be kept ...

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 ...

Sardines are a nutrient-rich fish widely consumed by humans. They are commonly served in cans, but fresh sardines are often grilled, pickled, or smoked. Sardines, or pilchards, are several types of small, oily fish related to herrings, family Clupeidae. The term sardine was first used in English during the early 15th century, and may come from the Mediterranean island of Sardinia, around which sardines were once abundant. The terms sardine and pilchard are not precise, and what is meant depends on the region. The United Kingdoms Sea Fish Industry Authority, for example, classifies sardines as young pilchards. One criterion suggests fish shorter in length than 6 inches (15 cm) are sardines, and larger ones pilchards. The FAO/WHO Codex standard for canned sardines cites 21 species that may be classed as sardines; FishBase, a comprehensive database of information about fish, calls at least six species pilchard, over a dozen just sardine, and many more with the two basic names qualified by ...

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.

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 ...

Accumulation of some heavy metals (copper, iron, manganese, nickel and zinc) and its effect on the hematological indices on the freshwater fish (Oreochromis niloticus) were studied. Fish Samples were collected from the River Nile near El- Kanater El-Khyria and contaminated water from Iron and Steel Basin in El-Safe Village near Helwan, south of Cairo. Results of this study showed that there was a significant difference between the water qualities indices among the two different locations. Meanwhile, fish samples that collected from polluted location showed high values for the hematological indices namely hemoglobin (Hb), red blood count (RBC), hematocrit (Hct), white blood cell count (WBC) and erythrocyte. Moreover, the concentrations of heavy metals were also high in the fish. However, the levels ofthe heavy metal accumulation were within the maximum permissible limit for human consumption (FAO, 1992). The order of bioaccumulation of such metals in the liver of fish were Fe | Zn| Cu | Mn | Ni. It was

The Lake Erie Center at the University of Toledo has been awarded a $209,126 federal grant to study a deadly fish disease that has threatened the health of many species of Great Lakes fish.. The grant, announced yesterday by U.S. Rep. Marcy Kaptur (D., Toledo), will fund a two-year study into viral hemorrhagic septicemia, or VHS.. It is an infectious viral disease present in several species of fish in the Great Lakes, including all-important walleye and yellow perch.. VHS has been responsible for several fish kills in the Great Lakes, including a kill of thousands of freshwater drum, or sheepshead, and yellow perch in central Lake Erie in the summer of 2006.. It is regarded by government biologists as the most dangerous fish virus in the world, though it poses no harm to humans.. For the first time, VHS recently was confirmed in fish beyond the Lake Erie watershed in inland Ohio - among muskellunge at Clear Fork Reservoir near Mansfield.. No fish kill has been recorded there to date, but state ...

The pattern of nasopharyngeal carcinoma incidence in China reflects the pattern of consumption of salted fish. Eight case-control studies consistently demonstrate that consumption of Chinese-style salted fish is strongly related to risk for nasopharyngeal carcinoma. The effect remained in studies that controlled for other risk factors. A significant dose-response relationship is seen between frequency of intake and risk for nasopharyngeal carcinoma, and the association is especially strong for intake of salted fish during childhood. Two further case-control studies, on oesophageal cancer and stomach cancer, found nonsignificant associations with consumption of Chinese-style salted fish. The association between cancer and the consumption of other types of salted fish was examined in several studies. A study in Tunisia and one in Alaska suggested a relationship between intake of salted fish and nasopharyngeal carcinoma. Ecological studies in Japan showed a correlation between consumption of dried ...

The Notothenioidei dominates the fish fauna of the Antarctic in both biomass and diversity. This clade exhibits adaptations related to metabolic function and freezing avoidance in the subzero Antarctic waters, and is characterized by a high degree of morphological and ecological diversity. Investigating the macroevolutionary processes that may have contributed to the radiation of notothenioid fishes requires a well-resolved phylogenetic hypothesis. To date published molecular and morphological hypotheses of notothenioids are largely congruent, however, there are some areas of significant disagreement regarding higher-level relationships. Also, there are critical areas of the notothenioid phylogeny that are unresolved in both molecular and morphological phylogenetic analyses. Previous molecular phylogenetic analyses of notothenioids using partial mtDNA 12S and 16S rRNA sequence data have resulted in limited phylogenetic resolution and relatively low node support. One particularly controversial result

Sturgeon first appear in the fossil record in the Triassic Period just over 200 million years ago and are among the most primitive of the bony fishes. Despite their large size and historic presence along the East Coast, Atlantic sturgeon were not targeted for their meat and caviar as a commercial fishery until 1880. By 1905 they had declined to less than one percent of their pre-fishing abundance but the fishery continued. Prior to 1980, there had been very little research on Atlantic sturgeon, primarily limited to documenting landing location and poundage, maximum longevity, or weight of eggs per fish. By 1990 most research into Atlantic sturgeon population dynamics had been focused on fisheries, and specifically, on when, where, and in what condition they were available for capture. The first true efforts at understanding population dynamics of Atlantic sturgeon led to the closure of all U.S. state and federal fisheries in 1998 and 1999, respectively. Much of the initial research on Atlantic sturgeon

Coastal exposure may affect the structure of littoral fish assemblages. To evaluate its effects, fish assemblages associated with shallow (0-3m depth) rocky reefs were investigated by visual census at the Asinara Island National Park (northwestern Sardinia, Italy, Mediterranean Sea) during autumn 2003. Distribution patterns of ichthyofauna in sheltered and exposed rocky reefs were assessed over the spatial scales of locations (i.e. kilometres) and sites (i.e. hundreds of metres). Overall, 38 fish taxa belonging to 17 families were recorded, with Labridae, Sparidae and Serranidae being the families with the most species. Univariate analyses showed that the average density of Labridae and Serranidae was significantly greater at sheltered locations, while particulate organic matter feeders (i.e. Mugilidae) were more abundant at the exposed ones. Significant differences in species richness, total fish abundance and densities of Labridae and planktivorous fish were observed at the spatial scale of ...

Atlantic cod (Gadus morhua L.) have been severely overexploited and are currently at historic population lows, having declined 90% in the North Sea and 99% off northeast Newfoundland in recent decades. Slow rates of recovery and continuing declines may be attributable to depensation, defined as a reduction in per capita growth rate concomitant with reduced population size. Several potential causes of depensation relate to low mating success and consequent reduced production of offspring. We explore the empirical basis of one of these in Atlantic cod using egg fertilization and male abundance data obtained from 21 experimental populations generated by three independent research programmes. We find support for the hypotheses that (a) fertilization rate declines with abundance and (b) variance in fertilization rate increases as population size declines. The former identifies one potential mechanism underlying depensation in Atlantic cod. The latter has negative genetic consequences for effective ...

Archer fish have been observed to knock down prey with a precise jet of water that is six times as powerful as the fish could generate with its own muscles. This allows the archer fish to take down aerial prey from inside the water.. The scientists published their findings in the journal PLoS ONE. This behavior of Toxotes jaculatrix was first described in the 18th century. The fish lives in mangrove forests and estuaries where there are many insects above water. This impressive strategy allows the archer fish to fetch food that would usually be out of its reach. The water jet can target and dislodge a single insect so that it falls into the water for the fish to consume.. Its still a mystery how T. jaculatrix is able to do so in less in a second. Scientists have hypothesized that the existence of a special organ in the fish body was the source. In this study, scientists put archer fish in to an aquarium to measure how accurate their water jet was. The fish was able to spout water at targets up ...

Fishing has been an important employment around the Mediterranean Sea for centuries but nowadays wild fish stocks are seriously depleted and the majority of Mediterranean gilthead seabream and sea bass is produced in fish farms. The aquaculture industry is relatively new in Greece, where these two species have only been farmed since the 1980s.. Selective breeding of many farmed fish species has progressed well, bringing substantial benefits to fish farmers in Europe - and to fish-eating consumers.. The selective breeding efforts of Mediterranean fish species have not yet been sufficient. But we are now boosting Mediterranean fish farming as well, said Greek biologist Konstantinos Tzokas.. Mr Tzokas is referring to FISHBOOST, a major research project whose goal is to improve the competitiveness of European aquaculture. Launched slightly over a year ago, the research project aims to ensure that in the near future, consumers on the Mediterranean shores will eat better quality fish produced ...

Fish and shellfish are an important part of healthy meal planning. They are a lean, low-calorie, high quality source of protein. They contain essential nutrients, omega-3 fatty acids, and are low in saturated fat.. Well-balanced meals that include a variety of fish and shellfish can contribute to heart health and childrens proper growth and development. Omega-3 fatty acids in fish benefit the hearts of healthy people and those at high risk of, or who have, cardiovascular (heart) disease.. However, some fish and shellfish (e.g., clams, oysters) may contain chemicals or illness-causing microorganisms like bacteria and viruses that could pose health risks to people. When contaminant levels are unsafe, fish and shellfish advisories help people make informed decisions about where to fish or harvest shellfish. Advisories recommend that people limit or avoid eating certain species of fish and shellfish caught in certain places.. All 50 states and some U.S. territories and tribes issue advisories to ...

TOXIC FISH ALERT / Survey finds mercury in 4 species at markets in Bay Area Four popular varieties of fish sold by high-end markets in the Bay Area contain toxic mercury at levels suspected of causing health problems, a Chronicle/CBS5 survey has found. Recent reports have raised new concerns about the mercury content of such big, ocean-caught fish as swordfish and tuna, including a study last year of local residents who ate fish several times a week. The Chronicle and CBS5 wanted to find out just how much mercury a consumer might be getting from fish sold at some of the Bay Areas best fish markets. The results underscore what many longtime fish lovers and health- conscious consumers may not completely understand -- that consuming large amounts of certain types of fish can jeopardize ones health. [...] for some people, particularly children and pregnant women, no amount of these fish would be safe. Dr. Jane M.

In this study, the concentration of alkylphenol ethoxylates (APEs) and brominated flame retardants (BFRs) were determined in fish samples, Labeo umbratus and Carp, collected from the Vaal River in South Africa. Ultrasonic-assisted extraction technique was used to extract the organic contaminants from fish samples, and the resulting extract was purified by sulphuric acid lipid removal followed by Strata X-cartridge SPE clean-up. The APEs and BFRs were derivatized using heptafluorobutyric anhydride before analysis with GC-MS. In both types of fish samples, lower oligomers of APEs were more abundant than the higher oligomers, while HBCD, BDE99 and PBB101 were the dominant BFRs. The concentrations of these pollutants ranged from 1.061 ng/g lipids (t-BP) in Labeo umbratus to 11.860 ng/g lipids (HBCD) in Carp.

We think there has been a shift in the food web resulting in more of the productivity being consumed in the water column, Collie explained. Phytoplankton are increasingly being grazed by zooplankton, which are then eaten by planktivorous fish, rather than the phytoplankton sinking to the bottom and being consumed by bottom fish. Its a rerouting of that production from the bottom to the top.. Collie noted that the increase in the numbers of lobsters and crabs is a result of their taking advantage of the benthic habitat abandoned by the bottom-feeding fish species. Overall, the survey analysis found huge changes in the abundance of some species. Butterfish and bluefish, for instance, have increased in abundance by a factor of about 100 times while cunner has decreased by almost 1,000 times.. The analysis also found that while the total number of fish caught in each trawl increased over time, peaking in the 1990s, the size of those fish decreased. While were catching more fish now, were also ...

Big Woods Fish And Game Preserve is a beautiful, private refuge that provides a unique, year around, fishing resort. Big Woods was designed in 1989 and constructed to be more than the average fishing and hunting clubs. The fish population in our preserve is many times greater than that which occurs naturally. This abundance of fish, as well as, greater numbers of large fish, is possible by carefully managing water and having periodic feeding programs.This enables a sportsman to expect an exciting action filled trip. Big Woods attempts to cater to the purest of sportsmen. We believe that it is the sport of fishing that intrigues large numbers as well as size is what were striving to achieve. our lake is stocked with a variety of fish such as bluegill, redear sunfish, Threadfin shad, Gizzard shad, fathead minnows, and golden shiners. Every species of fish in our preserve has a function in the overall eco-chain. these fish were selected not only to provide a source of food for the bass, but to develop an

The Apistogramma cacatuoides is commonly known as the Cockatoo Dwarf Cichlid or Big Mouth Apistogramma. The Apistogramma originates in the streams and backwaters of South America. This strain has been selectively bred for its brilliant orange coloration. The body of these fish is elongated, with a prominent dorsal fin. The rear part of the dorsal fin, as well as the tail, has a striking orange coloration. The Dwarf Cockatoo Cichlid should be kept in an aquarium that is 30 gallons minimum, with densely planted groupings. They require plenty of open swimming areas but also need hiding places. A fine gravel to sand substrate is recommended. Although a semi-aggressive fish, the Apistogramma is also timid and should not be housed with large, aggressive fish. They require good water conditions, and regular water changes are a must. The Dwarf Cockatoo Cichlid is an egg layer that prefers to spawn in caves. Once the female has laid her eggs, the male will follow to fertilize them. After fertilization, ...

This review looked at the evidence for the prevention and treatment of several heart conditions with omega-3 polyunsaturated fatty acids (PUFAs). The reviewers looked at observational and randomised trials of fish oil supplements and oily fish consumption for coronary heart disease (CHD), irregular heart rhythms (arrhythmia), congestive heart failure (enlarged hearts) and in people with high cholesterol or other fats in the blood. They also discuss some of the safety concerns about the mercury content of oily fish.. The reviewers explain that omega-3 fatty acids are found in oily fish, such as herring, mackerel, salmon, albacore tuna and sardines. A high intake can also be obtained from fish oil supplements or cod liver oil. The oils come from the marine micro-organisms that are eaten by fish and not made by fish themselves.. The evidence relates to two main types of omega-3 fatty acids, both of which are polyunsaturated oils: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). These are ...
