The present study was to estimate the acute toxicity of oil effluent on Cyprinus carpio and to evaluate the lethal levels. The 120 hrs median lethal concentration of oil effluent were found to be 80ppt for Cyprinus carpio. Furthermore experiments were continued with sub lethal concentration of (1/10th conc. of LC50) oil effluent which were evaluated from the LC50 value. After treatment the fishes were reared in ideal condition, then sacrificed dissected at different predetermined interval during the accumulation period, (i.e.) 1st day to 20th day, during the depuration period from 1st day to 15th day for Cyprinus carpio in oil effluent treatment for assay studies. The present study also show that oil effluent causes considerable modifications in enzyme activities and likely to induce tissue damage in Cyprinus carpio. Hence, this effluent should be handling with care and avoid its access into aquatic environment.
