饥饿循环处理对黄河鲤新品系幼鱼补偿生长性能的影响
Effects of cycle of starvation-refeeding on the compensatory growth performance of Cyprinus carpio haematopterus new strain juveniles
摘要
Abstract
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.关键词
