大口鲶幼苗阶段一般以摄食轮虫、枝角类、桡足类等浮游动物为食。在进行大口鲶苗种规模化生产中,这些活体饵料生物难以得到保障,制约了大口鲶苗种的规模化生产。因此,本试验采用不同饵料对不同发育阶段大口鲶苗种食性进行投喂试验,为解决苗种阶段的饵料供给问题作一尝试。一、
Larval catfish seedlings stage generally feeding rotifers, cladocera, copepods and other zooplankton for food. In the large-scale production of catfish seedlings, these living bait organisms are difficult to be protected, restricting the large-scale production of catfish seedlings. Therefore, different diets were used in this experiment to test the diet of large-fledged catfish seedlings in different developmental stages, and to try to solve the problem of feed supply during the seedling stage. one,
