摘要
对漠斑牙鲆Paralichthys lethostigma分别饥饿5、10、15 d(记为S5、S10、S15组)后再恢复投喂20d,分析了饥饿和再恢复投喂后全鱼的生化组成。结果表明:饥饿结束时,S5、S10、S15组鱼的体重损失率分别为1.18%、8.36%、11.76%,其中S15组的体重和饥饿前有显著差异(P<0.05)。在饥饿状态下,S5、S10组漠斑牙鲆全鱼蛋白质含量变化不显著,S15组则显著低于对照组(P<0.05);各饥饿组脂肪含量逐渐下降,并与对照组有显著差异(P<0.05);各饥饿组水分含量升高,且S15组达到显著水平(P<0.05);各饥饿组灰分含量高于对照组水平,且S10、S15组达到显著水平(P<0.05)。再投喂过程中,S15组蛋白质含量逐渐升高,各饥饿组脂肪含量逐渐升高,水分和灰分含量逐渐下降。
The biochemical composition was determined in south flounder Paralichthys lethostigma juveniles weighing （7.56 ± 0.63 ） g refed for 20 days 5 （ S5 ）, 10 （ S10 ） and 15 （ S15 ） days after starvation to evaluate the effect of starvation and refeeding on the biochemical composition. The results showed that body weight loss of 1. 18%, 8.36% and 11.76% was observed in S5, S10, S15 during the starvation, the body weight in group S15 being significantly lower than that at the beginning（P 〈 0.05 ）. There was no significant difference in protein content in whole body in the S5 and S10, but significantly lower protein content in the S15 than that in the control （P 〈0.05）. The lipid content in the whole body gradually decreased, and significantly lower than that in the control （ P 〈 0.05 ） while the water content increased, significantly higher in S15 （P 〈 0.05 ）. There was higher ash content in the whole body in the fish starved than that in the control with significant differences in the S10 and S15 （ P 〈 0.05 ）. During the refeeding, the protein content gradually increased while water and ash contents gradually decrease in all in S15, and the lipid content in the body gradually increased starvation groups.
