This investigation was undertaken to verify the prevalence of helminths parasites in the gastrointestinal tract of catfish. A total number of 116 catfish (Silurus glanis) were collected from Zarrine-roud river and examined for helminths. Fish were examined after washing contents of gastrointestinal tract and observed for the presence of helminths using a stereo microscope and a light microscope...

Objective: To study changes in selected liver enzymes of albino rats fed on diet formulated with catfish that were exposed for 30 days to water polluted with crude oil. Methodology and results: One hundred and twenty (120) catfish (Clarias gariepinus) in six groups of 20 catfish each were held for 30 h in water having five different concentrations of crude oil (0.1, 0.25, 0.5, 0.75 and 1% v/v)....

Plant proteins are plausible fishmeal substitutes but are deficient in some essential amino acids (EAA) like lysine and methionine. Combination of different plant proteins with complimentary EAA could be useful alternative. Bambaranut (Voandzeia subterranea) contains high amount of lysine while methionine is in sesame seed (Sesamum indicum). This experiment tested effects of combining sesame se...

Channel catfish virus (CCV) disease is an acute haemorrhagic disease in juvenile channel catfish (Ictalurus punctatus). While fish that survive primary CCV infection are suspected of being carriers of CCV, little is known concerning CCV latency. In this report, fingerling catfish were infected with CCV by experimental immersion challenge. Infected fish displayed clinical signs of CCV disease, b...

A seasonal study of the parasites of fish in the Hartbeespoort Dam was undertaken in 1979. This paper deals with 4 nematode species recovered from catfish, namely, Paracamallanus cyathopharynx (Baylis, 1923), Procamallanus laeviconchus (Wedl, 1862), Contracaecum sp. and Skrjabinocara sp. Total numbers of parasites recovered are tabulated and their seasonal variation illustrated diagrammatically...

An increased number of reports (by anglers, in the angling press) of European (wels) catfish Silurus glanis occurrences in the River Thames (England) has led to the perception that the species has become more abundant in that river. If proved true, then this would have ramifications for non-native species policy and practice. To assess catfish density, a total of 256 rod hours of specialized an...

Myostatin is a recently discovered gene that inhibits muscle growth. In the present study, we characterized the myostatin locus and its expression in channel catfish (Ictalurus punctatus). The genomic DNA and cDNA encoding the channel catfish myostatin were cloned and sequenced. The myostatin gene has three exons encoding a protein of 389 amino acids. Comparison of the genomic sequences with th...

So far, perch egg strands have been considered unpalatable biological material. However, we repeatedly found egg strands of European perch (Perca fluviatilis) in the diet of European catfish (Silurus glanis) caught by longlines in Milada and Most Lakes, Czech Republic. The finding proves that perch egg strands compose a standard food source for this large freshwater predatory fish. It extends t...
