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...

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...

Pearl Catfish (Clarias gariepinus) is a type of freshwater fish that widely cultivated by many people because its economic value. catfish new strain African Clarias gariepinus Burchell, 1822 superior breeding results the Sukamandi Fish Breeding Research Agency (BPPI) which has been declared passed in Type / Variety Release Assessment on October 27, 2014, under name MUTIARA (Peerless High Qualit...

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...

There is a strong competition from low-priced imported catfish fillets resulting in a declining market share for domestic farm-raised catfish fillets. To match the competition, catfish processors are embarking on pricing policy measures that are volume-oriented instead of profitor image-oriented. This could be an effective short-run pricing policy measure for optimal longrun sustainability and ...

INTRODUCTION Abscess formation and cellulitis in the setting of envenomation are rare complications of handling catfish. To the best of our knowledge, isolation of Proteus vulgaris has not been previously recorded, and recovery of Morganella morganii has been reported in only one prior case from wound cultures in patients injured by catfish stings. We report a case of catfish envenomation chara...
