Abstract
Chlorpyrifos is used extensively as a pesticide in consumer products for commercial agricultural applications as well as for household purposes. The aim of the present research is to evaluate the effect of a sub-lethal concentration of chlorpyrifos in the biochemical and cytological parameters of the Indian white shrimp, Litopenius vannamei, after 0,7,14,21 and 28 days of exposure. TP, TC and TL levels were significantly lower in test L. vannamei than in controls for all days of the experiment. Experimental gill tissue exhibited epithelial lifting, edema, necrosis, fusion of secondary lamellae, and bleeding. Infiltration, large lumen formation and disappearance of hemocytes were detected in the dead hepatopancreas. Muscle tissue exhibited pathological signs such as atrophy, necrosis, wavy appearance, accumulation of granular material between muscle fibers, fragmentation, loss of muscle structure, presence of basophilic deposits.
