Influence of insecticidal derivative (cartap hydrochloride) from the marine polycheate on certain enzyme systems of the fresh water fish Oreochromis mossambicus

The activities of phosphatases and transaminases were studied in muscle and liver of the fresh water fish, Oreochromis mossambicus on exposure to different sublethal concentrations (0.25, 0.5, 0.75 and 1 mgl(-1)) of cartap hydrochloride (insecticidal derivative from marine polycheate) for 96 h.
