春片培育的目的是提高鱼种成活率和培育大规格鱼种。在生产上大规格春片鱼种具有以下优点:一是大规格鱼种生长快,可缩短养殖周期,加速资金周转,提高经济效益。大规格鱼种的养殖周期要比小规格鱼种缩短1年左右;二是节省2龄鱼种池,为扩大成鱼池面积创造条件。规格大的春片草、青 The purpose of spring cultivation is to improve the survival rate of fish species and cultivate large-scale species. In the production of large-size spring species of fish has the following advantages: First, large-scale species grow fast, can shorten the breeding cycle, speed up capital flow, improve economic efficiency. Large-scale species of aquaculture breeding cycle shorter than the small size of species about 1 year; the second is to save 2-year-old fish species pool, to expand into the pond area to create the conditions.
