Abstract: By the methods of biochemistry, the activities of protease, amylase and lipase in the stomach, intestine and hepatopancreas of wild and farmed rockfish (Sebastes schlegeli) were determined under the conditions of 37 ℃ and optimum pH. Except the amylase and lipase activities in hepatopancresa, the test enzyme activities in the three organs of farmed rockfish were all higher than those of wild one. There were significant differences in the activities of the three digestive enzymes in stomach and intestine between wild and farmed rockfish (P<0.05), but no significant difference was observed in hepatopancreas (P>0.05). The differences in the digestive enzyme activities between wild and farmed rockfish could be resulted from the unstable and insufficient foods for wild rockfish in the natural environment.
