Studies on digestive enzymes of Haliotis asinina
耳鲍消化酶活力的研究

The digestive enzyme activities of Haliotis asinina at different stage were investigated in this paper..The results showed that the cellulase activities increased while the amylase activities decreased with the growth of H.asinina.There were no significant changes in lipase activities.The enzymatic activity order for different parts is: stomach>digestive gland> intestine.The ANOVA analysis showed that the amylase activities exhibited significant differences(P<0.05) between the stomach and intestine at the same stage,while no significant differences(P> 0.05)between the digestive gland and intestine,the digestive gland and stomach,respectively.The activities of cellulase were significantly different(P<0.05)between the stomach and digestive gland,the stomach and intestine,while not significantly different(P>0.05) between the digestive gland and intestine.
