不同饵料组成对花鲈幼鱼生长和生理活性影响研究
Effects of different diets on growth performance and physiological activities in Lateolabrax maculatus juveniles
摘要
Abstract
We fed juvenile Lateolabrax maculatus with Artemia (group 1), high protein (group 2), low protein (group 3), and frozen copepods (group 4) from 63 days after hatching (DAH) to 103 DAH to elucidate effects of different diets on growth performance and physiological activities. Final body length/weight, specific growth rate, average growth rate, and weight gain of group 2 were higher than those in the other groups. Pepsin and trypsin activities of group 1 peaked in the middle of the experiment, while the activities of the other groups peaked 103 DAH with significant differences. Amylase (AMS) activity of all groups increased during the experiment with the maximum in group 1 at 103 DAH. In addition, AMS activity of group 1 was significantly higher than that in groups 3 and 4. Lipase activity of group 1 tended to in-crease, whereas that in the other groups decreased. Lipase activity of group 1 was maximum at 103 DAH, whereas that in groups 3 and 4 was significantly lower than lipase activity in groups 1 and 2. These results show that L. maculatus juve-niles displayed better growth performance with protein-contained feed and that the Artemia diet led to poor growth per-formance, suggesting that low protein compound feed is cost-effective for rearing L. maculatus juveniles.关键词
