A 60‐day study was conducted to investigate the compensatory growth (CG) responses of sobaity (Sparidentex hasta) and yellowfin (Acanthopagrus latus) seabreams to restricted feeding ration and normal feeding ration phases during the nursery period. Fry stage of S. hasta and A. latus with initial weight (BW_i) of 1 and 0.8 g, respectively, were fed a commercial diet at five ration levels (RL) including 2%, 4%, 6%, 8% and 10% of their BWi over a period of 30 days (restricted‐ration phase) and then re‐fed up to visual satiation for another 30 days (normal‐ration period). According to the second‐degree polynomial relationship between specific growth rate and RL, the maintenance, optimum and maximum feeding rates for SGR in S. hasta were estimated to be 0.5%, 3.5% and 8.2%; meanwhile in A. latus, they were 0.3%, 4% and 8%, respectively. At the end of the normal‐ration phase, final body weight (BW_f) of S. hasta fed at 10% RL was higher than the other treatments. In addition, A. latus fed at 6% and 8% RL showed full CG regarding BW_f compared with fish fed at 10% RL. The findings of this study confirmed partial CG in S. hasta and full CG in A. latus after re‐feeding period.

育苗期相对于摄食率的Sobaity（Sparidentex hasta）和黄鳍鲷（Acanthopagrus latus）的补偿性生长

进行了为期60天的研究，调查了在育苗期中，咸鱼（Sparidentex hasta）和黄鳍金枪鱼（Acanthopagrus latus）鲷对受限摄食率和正常摄食率阶段的代偿性生长（CG）响应。的鱼苗阶段S.闪现和A.鲷用初始重量（BW_我1克和0.8克）分别以五种日粮水平（RL）喂食商业饮食，包括在30天内的BWI的2％，4％，6％，8％和10％（限制日粮阶段） ），然后再持续30天（正常配给时间）使视觉满足。根据比生长速率和RL之间的二次多项式关系，估计S. hasta中SGR的维持率，最佳和最大摄食率分别为0.5％，3.5％和8.2％。同时在A. latus中分别为0.3％，4％和8％。在正常定量阶段结束时，以10％RL饲喂的哈萨克葡萄链球菌的最终体重（BW _f）高于其他治疗方法。此外，A。latus与饲喂10％RL的鱼相比，饲喂6％和8％RL的鱼的BW _f完全CG 。这项研究的结果证实在部分CG S.闪现和全CG在A.鳍鲷再哺乳期后。
