Identification and specification of stress proteins in the liver tissue of Carassius auratus exposed to chlorpyrifos

In recent times the enormous usage of pesticides has led to a huge deterioration of soil and consequently the aquatic ecosystem and its inhabitants. Fishes are commonly the target animals due to pesticide contamination in water bodies at large. It is being understood that the fishes create a stress response towards the entry of toxic chemicals by means of synthesizing a group of novel proteins called stress proteins which play a major role in the stress- resistance. In the present study, the ornamental fish Carassius auratus (var.,) auratus was exposed to various concentrations of the organophosphorous pesticide, chlorpyrifos in various exposure periods and the nature of stress proteins synthesized were investigated.
