Comparative assessment of amylase and protease activities in the gut and hepatopancreas extracts of Macro brachium rosenbergii, Penaeus monodon, P. indicus and Metapenaeus monoceros, collected from Sundarban creeks along West Bengal, India, was done. alpha-amylase activity in gut and hepatopancreas was highest in M. rosenbergii followed by P. indicus, M monoceros and P. monodon and the levels of alpha-amylase activity was found elevated in gut of all four crustacean shrimp species as compared with hepatopancrease. Increased level of protease activity in gut and hepatopancreas were observed in P. indicus followed by P. monodon, M monoceros and M rosenbergii and the protease activity level was found highest in hepatopancrease of all four crustacean species as compared to levels of gut. Increased level of alpha-amylase activity in M. rosenbergii showed that carbohydrates are the principal substrates used for energy production in M. rosenbergii and gut might play an important role in the digestive process of carbohydrate in shrimps and prawn.
