设计4种投喂方式饲养黄颡鱼幼鱼,以测定不同投喂方式下黄颡鱼氮的收支和能量收支:第一种为连续投喂,整个试验期间不间断;第二种连续投喂3天后饥饿1天;第三种连续投喂6天后饥饿2天,第四种连续投喂12天后饥饿4天,4种方式分别以C(对照组),S1/3、S2/6和S4/12表示。结果显示,S1/3、S2/6和S4/12组的氮收支和能量收支模式与对照组差异显著,其生长氮和生长能比例显著高于对照组,排泄氮和代谢能比例显著低于对照组,因此,黄颡鱼的补偿生长来自于生长氮和生长能分配比例的显著提高。
Four feeding methods were designed to raise juvenile yellow catfish to determine the budget of energy and income of yellow catfish under different feeding modes. The first was fed continuously and uninterrupted throughout the experiment. The second continuous Starved for 1 day after feeding for 3 days, starved for 2 days for 6 days after the third continuous feeding, and starved for 4 days after the fourth continuous feeding for 12 days. The four methods were respectively C (control group), S1 / 3, S2 / 6 And S4 / 12. The results showed that the pattern of nitrogen budget and energy balance in the S1 / 3, S2 / 6 and S4 / 12 groups was significantly different from that in the control group, and the ratio of nitrogen and growth energy was significantly higher than that of the control group Lower than the control group, therefore, the compensatory growth of yellow catfish from the growth of nitrogen and the distribution of growth can significantly increase the ratio.
