| 摘 要： | 为研究克氏原螯虾在不同庇护所生境下的生长差异及其采取的不同生存策略,本实验在水池中设置洞穴、角落2种庇护所生境,并以无任何庇护所的水池为对照,饲养亚成体克氏原螯虾一个月.计算各组克氏原螯虾存活、生长的参数及耗饵量、转化率等摄食参数.实验结果表明,存活率指标以洞穴组最高,为84.0%,对照组最小,为22.0%;群体增重、...

| Abstract: | Procambarus clarkii is a species of aggressive animal with burrowing and typical social behavior.The purpose of the experiment is to find out the differences of crayfish's growth between different habitats and presume the differences in their living strategies.In the experiment,we set up two types of sheltered living condition for P.clarkii in the ponds including burrows and corners,and the control group without any shelter.After one month,we calculated the survival rate,total weight gain,individual weight ... |
