چکیده
The relative acute toxicity of Dichlorvos and Cypermethrin acting singly against Rainbow crab, Cardiosoma armatum was evaluated. effects sub lethal concentrations the pesticides on oxidative responses histopathological in gills crab were also investigated over a 30 days period. On basis 96 hrs LC50 value, with hr 8.86 ?g/L 2 times more toxic to crabs than 17.80 ?g/L. exposures (1/10th 1/100th LC50) both each resulted increase levels lipid peroxidation product, malondialdehyde (MDA) compared control group at day 15 bioassay . Super oxide dismutase (SOD) activity inhibited by for but activities Catalase (CAT) did not show significant trend (P > 0.05). Exposure concentration various such as curved filaments, fused epithelial lifting, congestion odema. damages severe those exposed Dichlorvous. findings from this study indicates that are potential threats non- target rainbow populations there is risk bioaccumulation transport food chain under
