Resumen:
The effect of organophosphate fenitrothion (FS) on non-target freshwater prawn Palaemonetes argentinus, was studied. Initially, 96-h LC50 h for FS was determined in adult prawns. Inhibition of cholinesterase (ChE) in muscle and hemolymph was assessed. Then, in the hepatopancreas the activities of superoxide dismutase (SOD), catalase (CAT), and glutathione-S-transferase (GST) were analyzed. Lipid peroxidation (LPO) was determined in the hepatopancreas also. The 96-h LC50 value was 1.12 ìg/L. Hemolymph ChE activity showed a significant decrease in exposed prawns to FS compared to the control group, while no significant differences in muscle were observed between groups (p
