Abstract

Indiscriminate use of pesticide has become a phenomenon among local fishermen in the Northern region of Niger state.Studirs were carried out using chronic toxicity bioassay to determine the effect of sub-lethal concentrations of 2,3-dichlorovinyl dimethyl phosphate (DDVP)on oreochromis niloticus (Trewavas,1983) under laboratory conditions.Experimental fish were exposed to test water separately diluted with sub-lethal concentrations of DDVP of 0.00,0.12,0.15,0.19, and 0.25mg/l.A 28 day exposure to sub-lethal concentrations of the toxicant resulted in changes in biochemical parameters of the fish on the exposure days (1,14, and 28)m Biochemical parameters such as total protein, albumin, globulin, and lactate dehydrogenase (LDH) decreased significantly (p<0.05) with incresing concentrations of the toxicant.Aspartate aminotransferase (AST), Alanine amino transferase (ALT), alkaline Phosphate(AlP) and acid phosphatase (ACP) increased significantly (p<0.05) with increasing concentrations of the toxicants.it is conclude that abnormalities in blood biochemical parameters were consequences of exposure to the toxicant (Sniper 1000EC).It is recommended that the use of DDVP by local fishermen be banned to saved aquatic ecosystem.
