在水温23~26℃条件下,对红鳍笛鲷进行不同时间的饥饿处理后,再进行恢复投喂试验,研究其生化组成的变化。试验结果表明:饥饿过程中,红鳍笛鲷肌肉(白肌)和肝脏的水分含量增加;肌肉的蛋白、脂肪含量下降;而肝脏的蛋白含量先上升后下降,脂肪含量增加,糖原含量显著下降。恢复投喂结束后,各项生化指标含量均恢复到对照组水平。
Under the condition of water temperature 23 ~ 26 ℃, the red snapper was starved for different time, and then returned to the feeding experiment to study the changes of its biochemical composition. The results showed that during the starvation stage, the water content of mussels (white muscle) and liver in redfin snapper increased, the protein and fat content of muscle decreased, while the liver protein content increased first and then decreased, the fat content increased and the glycogen content decreased significantly . After the resumption of feeding, the biochemical indicators were restored to the control group levels.
