Levels of Zn, Cu, Cd, As, and Pb in the kidney, Liver, Gills and Heart of African cat fish (Clarias gariepinus) from the Ogun River in Ogun State located close to six major industries in the South Western part of Nigeria, were determined using Bulk Scientific Atomic Absorption Spectrophotometer. Fishes were also collected from Government owned fish farm in Agodi, Ibadan which was considered a r...

Aim of the current piece work was to study food composition and feeding intensity Channa striata from Krishna river June, 2019 July 2020. The gut contents were analysed three stations undertaken fish. major components items in fish was: fishes their larvae, crustaceans, insect annelids with semi digested material unidentified items. Fishes are identified as teleost, particularly carps cat larva...

Dietary supplementation with royal jelly (RJ) may improve growth, antioxidant gene expression, and intestinal capacity, possibly mitigate effects of stress induced by high stocking density (HSD) in zebrafish (Danio rerio). Effects HSD RJ on growth performance, capacity were investigated. A total 240 four-month-old used a 2 x factorial design, four treatments three replications. The consisted no...

Background: Paraquat dichloride is a highly toxic herbicide which is still used in many developing countries. African cat fish (Clarias gariepinus) is a commercially important species in many countries and was selected assess accumulation and elimination of paraquat dichloride in its tissues. Methods: Groups of ten fish with equal lengths and weights were exposed to varying concentrations of...

Hadejia-Nguru wetland has been known to be a productive area of Agricultural engagements and fisheries activities allowing for intensive farming fishing activities, effluents from agricultural sewage, chemical seepages enter this water body. This study investigated the levels several heavy metals Mercury (Hg), Lead (Pb), Cadmium (Cd),Chromium (Cr), Aluminum (Al) in O. niloticus tissues (gills, ...

In this study, search for new mosquitocidal bacterium was attempted from the gut content of fresh water fish Clarias batrachus (walking cat fish) which resulted in isolation a highly potential bacterium. The isolate identified as Bacillus cereus VCRC 641 by species specific molecular markers ilvD, pur and pycA gene sequence analysis. Laboratory mosquito larval toxicity assay (bioassay) against ...

Antarctic fish of the suborder Notothenioidei have evolved several unique adaptations to deal with subzero temperatures. However, these adaptations may come with physiological trade-offs, such as an increased susceptibility to oxidative damage. As such, the expected environmental perturbations brought on by global climate change have the potential to significantly increase the level of oxidativ...

An outbreak of bacterial septicemia in female silver carp Hypophthalmichthys molitrix , which caused significant death the fish Yantian Reservoir, was investigated. The pathogen isolated from diseased and identified as Aeromonas veronii utilizing biochemical characteristics molecular methods analyses. artificial infection experiment indicated that strain 100% mortality juvenile mature with eggs...
