Abstract

The sensitivity of fish to a range of agrochemicals, including Ridoff (organophosphate insecticide) has been thoroughly examined. These chemicals can reach waterways through both deliberate discharge and approved agricultural practices. The toxic effect of Ridof was studied on fingerlings and post fingerlings of Clarias gariepinus for thirty days using the following concentrations: 0.025mg/l, 0.020mg/l, 0.015mg/l, 0.010mg/l, 0.00Mg/l (Control). The Fingerlings and Post fingerlings had a mean weight of 15±00g, 69.5±00g respectively and the mean length for the fingerling was 8.65±00cm and that of Post fingerling was 9.67±00cm.The sub-lethal exposure showed a decrease in weight of fish with increase in concentration. The Biochemical analysis showed a significant effect on some enzyme indices such as AST (Aspartate aminotransferase), ALP (Alkaline phosphatase) and ALT (Alanine aminotransferase). The Haematological study also showed a significant effect on the White blood Cell (WBC), Packed Cell Volume (PCV) as well as the Haemoglobin (HB). In all the parameters measured – enzymes, blood and condition factor, catfish fingerlings were less impacted by toxicant when compared with post fingerlings. Ridoff (Organophosphate insecticide) had a severe effect on the two life stages of the exposed fish. So, the use of Ridoff (Organophosphate insecticide) near fish farms or in areas close to aquatic environment should be discouraged.
