"Toxic effects of 4-nonylphenol on the embryonic development of African catfish Clarias gariepinus (Burchell, 1822) ''
The present study investigated effects of environmental relevant concentrations of 4-nonylphenol (0.05 to 0.08 to 0.1 mg/l) on the reproduction and embryonic developmental stages of catfish (Clarias gariepinus). To determine the effect of 4-nonylphenol on reproduction; catfish were exposed to three concentrations of 4-nonylphenol in a flow-through-system during spawning period (some for one wee...
متن کاملEffects of testosterone propionate on growth, survival and sex-ratio of african catfish (Clarias gariepinus Burchell)
For studying the effects of different levels of testosterone propionate on growth, survival and sex-ratio, five different doses such as 125, 100, 75, 50, 25 mg hormone per kg feed were administered to 5-day old Clarias gariepinus fry through diet for a period of 40 days. The growth performance in terms of weight and length gain of the fry receiving 100 and 75 mg hormone per kg feed were signifi...
متن کاملAffinity purification and partial characterization of IgM-like immunoglobulins of African catfish, Clarias gariepinus (Burchell, 1822).
IgM like macroglobulin from bovine serum albumin (BSA)-immunized African catfish C. gariepinus was purified by affinity chromatography and partially characterized. The molecular weight of this macroglobulin was 840 kDa, as estimated by gel filtration chromatography. Purified macroglobulin was analyzed using SDS-PAGE under reducing and non-reducing conditions. The molecular weight (MW) of heavy ...
متن کاملGrowth response of African catfish, Clarias gariepinus (Burchell) to varied protein and lipid levels.
To study the growth response of African catfish (Clarias gariepinus) to the diets containing two protein (30 and 35%) and two lipid levels (12 and 18%) in a closed recirculatory system for 60 days, fish were fed to satiation twice daily. The experiment was carried out in triplicate groups. Fortnightly sampling of fish and water samples was carried out. The best result in terms of growth was obt...
متن کاملHistopathological Effects of Glyphosate on Juvenile African Catfish (Clarias gariepinus)
Most aquatic herbicides have undergone some toxicity testing for effects on non-target aquatic organisms, little of this testing has been conducted on early life stages of Clarias gariepinus. African catfish C. gariepinus were exposed to acute concentrations of glyphosate for 96hrs. The lethal concentration (LC ) 5O value of glyphosate was 0.295 mg l for 96h of exposure. The mean mortality perc...
