Identification and specification of stress proteins in the brain tissue of Carassius auratus Exposed to Chlorpyrifos

Environmental pollutants pose a huge menace to all living organisms either directly or indirectly. Pesticide contaminations in the aquatic ecosystem affect the fishes at large leading to severe physiological and morphological stress response. Fishes in turn to counter the stress factors, ought to synthesize a group of novel proteins called stress proteins which play an important role in the stress-resistance of cells against the toxic chemicals. In the present study, the ornamental fish Carassius auratus (var.,) auratus was exposed to different concentrations of the organophosphorous pesticide, chlorpyrifos in various exposure periods and the type of stress proteins synthesized were investigated.
