In this study, fertilized eggs and 3-28 day-old larvae of Liza haematocheila were selected as the research objects. The growth characteristics and changing trends of main digestive enzymes were researched. The relationship between total length or body mass and day old could be fixed to the exponential functions. The general correlation equation of total length and body mass was power function under artificial farming conditions, and the growth (in mass) in relation to total length was allometric. The activities of trypsin, pepsin, amylase, alkaline phosphatase and acid phosphatase could be detected in all test samples, while lipase activity could not be detected. Enzymes (except pepsin) activities were the lowest in fertilized eggs. Pepsin activity showed a rapid decrease from 3 to 16 day-old, and reached to the minimum level at 16day-old. Meanwhile, trypsin activity increased significantly at first, and reached the maximum level at 10 day-old, then bagan to decrease. Both pepsin and trypsin activities increased significantly from 16 day-old (P<0.05), and reached the maximum levels at 28 day-old. Amylase activity increased from 3 to 10 day-old and 22 to 28 day-old, respectively, and reached the maximum at 28 day-old. Both alkaline phosphatase and acid phosphatase activities increased significantly from 3 to 7 day-old (P<0.05). Alkaline phosphatase activity decreased from 7 to 22 day-old, while acid phosphatase activity remained stable. Alkaline phosphatase and acid phosphatase activities reached the maximum levels at 7 and 8 day-old, respectively. In conclusion, digestive enzymes were not caused by exogenous bait, and the activities were closely related to development stage and also were affected by external environment and feeding habit in different degrees.
