Title: Comparison of Digestive Enzyme Activities in Monopterus albus of Different Sizes
Abstract: Monopterus albus of three sizes in this study were cultured for two mouths in the same aquaculture condition.The activities and distributions of protease,lipase and amylase in liver,fore-intestine and hind-intestine of M.albus of three sizes[(143.81±36.27) g,(76.63±14.43) g,and(31.35±5.82 g)] were examined by using enzyme analytical methods.Results obtained here showed that: the decreasing order of protease activity in M.albus was fore-intestinehind-intestineliver,whilst the decreasing order of amylase and lipase activity in M.albus was hind-intestinefore-intestineliver;as body weight of M.albus increased,intestinal protease activity gradually increased and the protease activity in liver did not change significantly;the amylase activities in hind-intestine and liver increased with the body weight increasing,however,the amylase activity in fore-intestine had an opposite trend;M.albus in medium-size presented higher lipase activity than those in big-size and small-size.
