Abstract

Toxicant in aquatic environment enters can be either directly in the medium or through air. Pesticides production and use have shown remarkable increase in india & their indiscriminate use in agricultural & forestry has poses a great threat to aquatic environment and hence ,fish become one of the immediate targets of such biocidal doses that of terrestrial animals. It is also possible that the insecticides run off & drift during insect control operations may prove sufficient to kill fish (scott ,1967 , Trim 1987 ).
