Abstract:The Dimethoate is one of the pesticide most widely used in agriculture sector in Maharashtra to control the varieties of pests and ectoparasites. The acute toxicity bioassay tests were conducted at various concentrations ranging from 5.0 and 13.0 mg/l freshwater fish, Rasbora daniconius for 24, 48, 72 and 96 h. The acute toxicity values were determined as 11.58, 10.25, 10.63 and 9.13 ppm respectively under laboratory conditions respectively. These LC50 values showed that the chemical is highly toxic to the fish. Then the fish were exposed to sub lethal concentrations 96 h LC50 9.13 ppm and studied the significant changes in glycogen, Protein and lipid levels of the fresh wet tissues. In the present investigation glycogen content of muscle, gill, liver and kidney as 12.78, 9.01, 42.30 and 11.12 mg/gm/wet.wt of tissues respectively. In Protein content of muscle, gill, liver and kidney as 18.04, 10.39, 15.85 and 10.02 mg/gm/wet.wt of tissues respectively and lipid content of muscle, gill, liver and kidney as 59.01, 49.23, 68.01 and 55.25 mg/gm/wet.wt of tissues respectively. In glycogen, protein and lipid content decreases in all tissues when compared with the control group.
