| Abstract: | Protease activity and amylase activities in digestive organs of Pseudobagrus fulvidraco were measured and analyzed. The results showed that the optimum pH for protease activity were 2.5,7.0,6.0, 7.0 and 7.0 in stomaches, hepatopancreas, foregut, midgut and hindgut of Pseudobagrus fulvidraco respectively. The protease and amylase activties were, in turn, from high to low in stomaches, intestines and hepatopancreas. Protease and amylase activities in intestine were the highest in the midgut. |
| Keywords: | Pseudobagrus fulvidraco protease amylase enzyme activity |
