Abstract

Abstract

The specific activities of digestive enzy mes of Lutjanus sebae juveniles were determined during starvation and refeeding.The fish were starved for 0(control), 2, 4, 6, 9, 11d and refed for 10 d with enough food.The specific activities of protease, lipase and amy lase were determined during starvation and refeeding.The results showed that the specific activities of protease and lipase decreased clearly during the starvation, but the specific activity of amylase had a bigger wave;after refeeding, the specific activities of protease and lipase had a little rising, but the protease specific activity was lower than the control group while lipase was higher.The specific activity of amylase had no change compared with the control group.
