研究了亲鱼选择、暂养和苗种的饵料转换、日常管理和病害防治等一套工艺流程,在300m3育苗水体中,育出26.7mm以上黑鲪鱼苗32.15万尾,鱼苗培育成活率33.5%。专家鉴定认为,本成果总体达国内先进水平,其中产仔率、单位水体出苗量等方面属国内领先。
A set of technological process of broodstock selection, maintenance and seed conversion, daily management and disease control was studied. In the 300m3 seedling water body, 321,500 tails of blackheadfishes were raised, and the survival rate of fry breeding 33.5%. Experts believe that the results of the overall domestic advanced level, of which birth rate, the unit of water emergence and so on are the leading domestic.
