The Effect of Lambda cyhalothrin on Transferases, Urea and Creatinine in Organs of Parohiocephalus obscurus, a Common Niger Delta Wetland Fish

The aim of this study was to unveil the effects of lambda cyhalothrin on transferase, urea and creatinine in Parophiocephalus obscurus. Thirty adult fish (mean length, 15.50 ±0.2cm) were acclimatized to laboratory condition for 10 days and then exposed to varying sublethal concentration of the toxicant (0.012, 0.024, 0.036mg/l) in semi static bioassay for 14 days. Tranferases (aspartate amino tansferase (AST), alanine amino transferase (ALT) were determined in the liver and muscle while creatinine and urea were determined in the muscle and kidney. Transferase values were significant (p<0.05) in the organs tested. A dose dependent decrease was recorded in the liver AST and muscle ALT while a dose dependent increase was recorded in the liver ALT and muscle AST. Muscle and kidney urea were not significant unlike creatinine in the muscle and kidney. The enzymes tested could be more useful biomarkers of sublethal effect of lambda cyhalotrin on Parophiocephalus obscurus. The results clearly unveiled the potential effect of lambda cyhalothrin
