摘    要:研究了日本囊对虾在饥饿和再投喂下血糖、肝胰脏糖原和肌糖原含量的变化.结果表明:在饥饿状态下,日本囊对虾肝胰脏糖原含量和血糖浓度在饥饿开始时迅速下降,肌糖原含量在饥饿10 d时下降到最低值,在饥饿10~15 d时通过糖原异生作用又恢复至最初水平,但随着饥饿时间的延长,糖原含量持续下降.恢复投喂后,肝胰脏糖原含量和肌糖原含量均能得到较好恢复,饥饿10 d和 15 d组的血糖浓度在恢复投喂10 d后显著高于对照组,但饥饿25 d组的血糖浓度始终显著低于对照.表明饥饿时间过长,对血糖浓度的恢复有较大影响

关 键 词:日本囊对虾  饥饿  再投喂  糖代谢

Abstract:This paper studied the variations of glucose concentration in haemolymph and glycogen concentration in hepatopancreas and muscle of Marsupenaeus japonicus under starvation and re-feeding.Groups C,S1,S2 and S3 were deprived of food for 0,10,15 and 25 days,respectively,and then re-fed for 10 days.Under starvation,the glucose concentration in haemolymph and glycogen concentration in hepatopancreas decreased rapidly at the beginning,and the glycogen concentration in muscle was the lowest after 10-day fasting.In the following 5 days,the glucose concentration in haemolymph and glycogen concentration in hepatopancreas and muscle recovered to their initial levels due to gluconeogenesis,but the glycogen concentration kept declining with fasting.After re-feeding,the glycogen concentration in hepatopancreas and muscle recovered well,and the glucose concentration in haemolymph had a sharper increase in groups S1 and S2 than in group C,but was markedly less in group S3 than in group C.These results indicated that long-term starvation had a greater effect on the glucose concentration in haemolymph.
Keywords:Marsupenaeus japonicus  starvation  re-feeding  carbohydrate metabolism
