Abstract

Juveniles of Oreochromis niloticus (mean body weight 7.05± 1.02cm) were subjected to sniper 1000EC at 5 sublethal treatment levels of 0.00, 0.12, 0.15, 0.19 and 0.25mg/L. There was no significant difference between water quality parameters of the exposed and control groups. A 21 day exposure to sublethal concentrations of the toxicant led to a significant decrease (p<0.05) in (specific growth) weight of the exposed fish in comparison with their controls. The effects on liver and kidney were observed majorly at 0.19 and 0.25mg/L of the exposed fish. Liver tissues revealed steatosis, haemosiderosis and vacuolations. Kidney tissues revealed tubular nephrosis and hyperplasia. It is concluded that abnormalities in body weight and visceral organs of the exposed fish were consequences of exposure to the toxicant. It is recommended that the use of Sniper 1000EC by local fishermen be banned to save the aquatic environment from destruction.
