近年来,胡子鲶作为池塘养殖新品种而被人们重视,但因鱼苗种培育成活率低,鱼种供不应求,致使其养殖规模不大,严重阻碍生产的发展。为了提高苗种成活率,我们对蟾胡子鲶(Claras batrachus)及本地胡子鲶(Claras fuscus)仔、稚鱼在饲养条件下的一些摄食特性进行了观察,现将结果报告如下。一、材料与方法胡子鲶仔、稚鱼对丰年虫摄食量观察,是在室内一口鱼苗培育池中进行的,试验池水温27～31℃。饲养密度为7,000尾/平方米。在仔鱼开始摄食之日起,逐日取样10尾,经50％酒精固定后,分别测其体长,解剖观察
In recent years, bearded catfish as a new breed of pond has been valued by people, but the survival rate of fish breed is low and the supply of fish is in short supply, resulting in a small scale of breeding and seriously hindering the development of production. In order to improve the survival rate of seedlings, we observed some feeding characteristics of juveniles under the feeding conditions of Claras batrachus and local Claras fuscus, and the results are reported as follows. First, the material and methods Bearded Abalone, juvenile feeding on the abundance of Artemia observation, is a indoor fish fry incubation pool, test pond water temperature 27 ~ 31 ℃. The stocking density is 7,000 fish per square meter. In the larvae began feeding on the day after sampling 10, after 50% alcohol fixed, respectively, measured body length, anatomical observation
