Sublethal Effects of Tobacco (Nicotiana Tobaccum) Leaf Dust on Enzymatic Activities of Heteroclarias (a Hybrid of Heterobranchus Bidorsalis and Clarias Gariepinus)
Tobacco (Nicotiana tobaccum) leaf dust has both piscicidal and fertilizer properties. Thus there is a need to study its effects at sub-lethal concentrations (375.60, 187.80, 93.90 0.0mg/L) on some enzymatic activities of Heteroclarias in a static semirenewable bioassay system with the aim to ascertain its effect on the test fish after the 14 days exposure period. Water quality parameters and ph...
متن کاملEmbryonic and larval developmental stages of African giant catfish Heterobranchus bidorsalis (Geoffroy Saint Hilaire, 1809) (Teleostei, Clariidae)
The dearth of African giant catfish Heterobranchus bidorsalis seeds poses great threat to its aquaculture and biodiversity, hence detailed knowledge and understanding of its embryology is indispensable for its artificial propagation and conservation programmes. Photomicrographs of extruded oocyte through all developmental cell stages of live embryo to larval stage are documented with the aid of...
متن کاملEffect of different levels of phosphorus on growth and mineralization in African giant catfish Heterobranchus bidorsalis (Geoffrey Saint Hillarie, 1809) NWANNA, L.C;
Eleven diets (D1-D11), designated as treatments (T1-T11), supplemented with different levels of inorganic phosphorus (P) (Ca2PO4) were fed to Heterobranchus bidorsalis (10.8 ±0.02 g) to determine the optimum P requirement. D1 D11 contained total P of 10.2, 10.4, 11.0, 11.9, 12.3, 12.6, 13.4, 13.9, 14.2 14.7 and 15.4 g kg respectively. After 84 days of feeding trial, there was increase in fish g...
متن کاملEffects of dietary fish oil replacement by vegetable oil on the serum biochemical and haematological parameters of African catfish (Heterobranchus longifilis) fingerlings
The present study aimed to elucidate the impacts of dietary vegetable oil blends as alternative to fish oil on serum biochemical and haematological parameters in Heterobranchus longifilis fingerlings. Fish (4.65 ± 0.23g) were fed diets containing fish oil (FO), palm oil (PO), soybean oil (SO), blend of PO and SO (POSO) over a 12-week period. The experiment was carried out in 62-l circula...
