Has determined the pepsin which, the chymotrypsin, the trypsin, the bright peptide enzyme, the lipase, the phospholipase, the alkalinity phosphatase and amylase activeness with the raid of two kind of size's large yellow croaker (Pseudosciaena crocea) the stomach, the intestinal tract and the pyloric caeca contains, and has carried on the comparison separately to between two group of fish's each digestion enzyme activities. The experiment obtains in the stomach to contain the proteinase is the acidic proteinase, activeness reduces under the neutrality and the alkalinity condition; The intestinal tract and the pyloric caeca proteinase mainly for the neutrality and the alkalinity proteinase, the alkalinity protein enzyme activity is higher than the neutral proteinase. The big fish group's pepsin, the pyloric caeca chymotrypsin, the amylase and the phospholipase, the intestinal tract bright peptide enzyme is higher than the small fish group, other enzymes are lower than the small fish group each alimentary organs to contain. Between two group of fish's pepsins, the stomach amylase, the stomach alkalinity phosphatase, pyloric caeca's alkalinity phosphatase and intestinal tract's chymotrypsin, the phospholipase have the remarkable difference. The big fish group and the small fish group's trypsin, the chymotrypsin, the bright peptide enzyme, the lipase and the phospholipase active change tendency is from the stomach, the pyloric caeca, the intestinal tract elevates gradually, the starch enzyme activity is from high to low: The pyloric caeca > the stomach > the intestinal tract, big fish alkalinity phosphatase's activeness is from high to low: The intestinal tract > the pyloric caeca > the stomach, small fish alkalinity phosphatase's activeness is from high to low: Pyloric caeca > intestinal tract > stomach.
