| 为探究黄河鲤新品系幼鱼在饥饿-饱食循环状态下的生长补偿特点，选用初始均质量（23.44±3.21）g的黄河鲤幼鱼360尾，随机分成4个实验组，每个实验组3个重复，每个重复30尾鱼，分别按处理组A组：饥饿5 d（S5）饱食20 d（F20）；B组：S7-F28；C组：S15-F60；对照组Con：F75的投喂方案饲养，养殖实验为75 d。研究表明：（1）经过不同时长的饥饿，在恢复饱食投喂阶段，A组的特定生长率（SGR）为1.70%，显著高于B组的1.08%、C组的0.87%以及对照组Con的0.60%；（2）在饥饿阶段，3个处理组A、B、C的体长特定生长率（SGRL）显著低于对照组Con；当恢复投喂后，A组、B组的SGRL则显著高于C组和对照组Con；（3）在饥饿阶段，A组的肥满度特定生长率（SGRK）显著低于B组、C组和对照组Con，但在恢复投喂阶段，却显著高于B组、C组和对照组Con。（4）处理组A节省饲料率为8.7%，较另外两个处理组高。由试验结果可以看出，饥饿5 d饱食20 d循环3次的投喂方式能激发幼鱼产生部分补偿生长效应，且饲料投喂量最少。 |

| In order to explore characteristics of compensatory growth of juvenile Cyprinus carpio haematopterus new strain in cycle of starvation-feeding, we chose 360 juveniles with the initial mean weight of (23.44±3.21) g, and divided them into 4 groups randomly, each group was set to 3 repeats containing 30 individuals. Fish were fed in four feeding schedules as follows: Starvation A:5 days starvation (S)-20 days feeding (F)-5 S-20 F-5 S-20 F; Starvation B: 7 S-28 F-7 S-33 F; Starvation C: 15 S-60 F; Control group Con: 75 F. The experiment lasted 75 days. The results show that: (1) In the recovery of satiation period after starvation, the specific growth rate (SGR) of the A group was 1.70%, significantly higher than that of the group B of 1.08%, group C of 0.87% and Con of 0.60%; (2) During the starvation period, the specific growth rate of body length (SGRL) of three treatment groups was significantly lower than that of the Con, but significantly higher than Con after refeeding. (3) At the starvation period, the specific growth rate of condition factor K (SGRK) of group A was significantly lower than those in the group B, C and Con, but significantly higher after the satiation period. (4) the feed rate of A in the treatment group was 8.7%, higher than the other two groups. Based on the SGR as the main evaluation index, the results indicated that the way 5 days starvation (S)-20 days feeding (F) can arouse juvenile Cyprinus carpio new strain to have partially compensatory growth effect and save 8.7% of the feed consumption. |
