IMPACTS OF MORINGA DIETS ON PHOSPHATASES ACTIVITIES IN COPPER EXPOSED FISH, CYPRINUS CARPIO

Sakthi Bama, Dr. B. Geetha

Abstract :

The acid or alkaline phosphatases activity of liver, gill and muscle of C. carpio was 1.42 or 4.38, 0.17 or 3.47 and 0.12 or 2.35 mg p–nitrophenol released mg^–1 protein hr^–1 respectively in C. carpio. Acid and alkaline phosphatases activities were significantly (P < 0.05) declined with an extension of exposure period in copper exposed fish received control diet. However, both the phosphatases activities were declined in early exposure period (20 – 40 days) and thereafter they were enhanced and moved towards normally in copper exposed fish received Moringa diets. Among the Moringa diets, 30% diet (M2 group) exhibited the better performance on the reduction of copper toxicity and an improvement of phosphatases activities in tissues as compared to other diets
