Toxicity of Buprofezin on the Survival of Embryo and Larvae of African Catfish, Clarias gariepinus (Bloch)
Buprofezin is an insect growth regulator and widely used insecticide in Malaysia. The present study evaluated the toxic effects of buprofezin on the embryo and larvae of African catfish (Clarias gariepinus) as a model organism. The embryos and larvae were exposed to 7 different concentrations (0, 0.05, 0.5, 5, 25, 50 and 100 mg/L) of buprofezin. Each concentration was assessed in five replicate...
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...
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 کاملResponses of growth rates and growth hormone levels of African catfish (Clarias gariepinus) to stocking density
In order to estimate responses of growth rate and growth hormone of Clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-L tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. On day 30 and 60, the fish growth rates were measured, pituitary growth hormone (GH) mRNA levels and serum GH concentrations were examined by real-time qPCR and ELISA te...
