THE EXPERIMENTAL STUDIES ON ACTIVITIES OF DIGESTIVE ENZYME IN THE LARVAE PENAEUS CHINENSIS

PAN Lu Qing and WANG Ke Xing (Fisheries College,Ocean University of Qingdao, 266003)  
Activities of several digestive enzymes from larval Penaeus chinese were analyzed with the enzyme analytical method during its ontogenetic development. The results showed that there were 4 different patterns in the activities of 5 digestive enzymes from larval prawn. The activities of pepsin enzyme and tryptase increased along with the growth of larval prawn,while the activities of amylase decreased. The activities of cellulase enzyme and lipase were fairly low. The activities of pepsin enzyme,trytase and amylase changed obviously in feeding habits transformation. The activities of digestive enzyme from larval prawn were affected obviously by the different diets and ontogentic development. The authors suggested that the activities of digestive enzyme in the larval prawn were associated with its genetic control and liver differentiation and adjusting mechnism.
