The African sharptooth catfish (Clarias gariepinus) is indigenous to South Africa where it is commonly found in calm waters such as lakes, streams, rivers, swamps and floodplains. The males of this gonochoristic species can be readily distinguished from females via a distinct elongated urogenital papilla with a pointed tip, located just behind the anus. This structure is an androgen controlled ...

Aiming at finding cheaper and still efficient feed for aquaculture species 56 days feeding trial was conducted on African catfish (Clarias gariepinus) post fingerlings, fed five diets with a 40% crude protein target in which maize replaced offal meal 0%, 25%, 50%, 75%, 100% respectively. Ten fish each were stocked plastic aquarium tank containing 20 L of water. The 5% body weight divided into t...

Cellgevity® is a supplement reported to comprise mostly D-Ribose and L-Cysteine enriched glutathione, known be an effective antioxidant that improves spermatozoa quality. However, its effect on milt characteristics has not been reported.

laboratory-scale experiments were conducted to evaluate the joint action toxicity and biochemicaleffects of sublethal concentrations of forcados light crude oil (flco) and three dispersants against clariasgariepinus over a period of 28 days. the derived 96hrlc50 values revealed that the dispersant, ds/tt/066(0.03ml/l) was the most toxic, followed by dispersant, oc/tt/osi (0.19ml/l), flco (5.06m...

Clarias gariepinus is one of the freshwater fish that easy to culture, but also susceptible Edwardsiella tarda infection. Although this convenient treated, consequences bacterial infection are quite detrimental. The method used in study a biochemical test followed by histopathological examination observe tissue changes occur organ. results showed 5 out 17 samples were infected with pathological...

Ameliorative potential of antioxidants –vitamins C and E on blood profile of Clarias gariepinus fed diets contaminated with varied levels of fumonisin B1 (FB1) was evaluated. Fusarium cultured maize containing FB1 were used to formulate diets containing approximately 2.5, 5.0, and 7.5 mg FB1/kg constituting diets 2, 3, and 4, respectively and other nine diets constituting Diets 5 - 13 with the ...

The present study was aimed at evaluating the effects of different concentrations of the most commonly used fish antimicrobial drug, chloramphenicol (CAP), on the behavior and hematological parameters of Clarias gariepinus. Fish specimens were exposed to three (2.5, 5.0 and 10.0 mg L(-1)) sublethal concentrations of CAP and a control. Abnormal behavioral changes were observed in fish exposed to...

Large numbers of adult Nile crocodiles, Crocodylus niloticus (Laurenti), died from pansteatitis during autumn and winter 2008 in the lower Letaba and Olifants River gorge in the Kruger National Park, South Africa. Consequently, the health status of fish from these waters was investigated. The study presents the pathological findings in fish inhabiting these rivers within the boundaries of the P...
