| Abstract: | An expriment was conducted to determine the activities of pepsin and trypsin-like enzyme in the larvae of Litopenaeus vannamei Boone using enzyme analytical method. The results indicated that the activities of pepsin and trypsin-like enzyme increased with the growth of larval prawn: zoea stageLitopenaeus vannamei Boone. During feeding habits changing, the activities of pepsin and trypsin-like enzyme in the post larval stage increased the most, and the activities of trypsin-like enzyme increased higher than that of pepsin. |
