ABSTRACT

Indiscriminate usage of pesticides in agriculture is posing a great threat to the environment and its associated fauna. Pesticides from site of their application through various ways ultimately reach aquatic bodies and change the quality of the medium. Any change in the habitat due to a particular toxicant definitely affects the tolerance limit of aquatic fauna and negatively influence their growth, survival and reproduction. These negative consequences created by pesticides are ultimately leading to a disturbance in the delicate balance of ecosystem. It is important to evaluate the acute and chronic effects of various pesticides on various non-target species such as fish. In Aquatic toxicology studies, acute and chronic tests are useful to estimate the concentrations of certain pesticides that cause direct and irreversible damage to the aquatic organisms. In the present review, an attempt has been made to elucidate the toxic impact of dimethoate on fish, a non-taget species.
