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 کاملOptimization of Supercritical CO2 Extraction of Fish Oil from Viscera of African Catfish (Clarias gariepinus)
Fish oil was extracted from the viscera of African Catfish using supercritical carbon dioxide (SC-CO(2)). A Central Composite Design of Response Surface methodology (RSM) was employed to optimize the SC-CO(2) extraction parameters. The oil yield (Y) as response variable was executed against the four independent variables, namely pressure, temperature, flow rate and soaking time. The oil yield v...
متن کاملToxicity of Copper (11) Tetraoxo Sulphate to African Catfish (Clarias Gariepinus) Fingerlings
This study was carried out to determine the toxicity of copper sulphate to African Catfish (Clarias gariepinus). The range – finding test was conducted twice in order to get reliable values that could be used for the definitive test. The toxicant (copper sulphate) was introduced at varying concentrations of 10g/l, 20g/l, 30g/l and 40g/l in the first rangefinding test, while it was introduced at...
