缩短团头鲂养殖周期的关键是培育出大规格鱼种。试验结果表明 :合理搭配放养品种、选用良种团头鲂和不同型号的沉性颗粒饲料 ,每千平方米放 2 .4万尾良种团头鲂夏花鱼种可培育出 1.5万尾平均规格为 66.7g/尾的大规格鱼种。主养鱼单产达每千平方米 10 89kg ,平均利润 2 72 1元 /10 0 0m2 。大规格鱼种培育技术的研究成功使团头鲂的养殖周期缩短至 2年成为可能 ,这对稳定常规鱼类生产、提高传统水产品养殖效益具有积极意义。
The key to shortening bingo breeding cycle is to breed large size fingerlings. The results showed that: with reasonable breed stocking varieties, choose the best breed and other types of sub-Shen Shen pellet feed per square meter put 2200 species of wild breed head 鲂 summer fish species can cultivate an average of 15,000 66.7g / tail large size species. The main fish yield of 10 89 kg per thousand square meters, the average profit of 2 721 yuan / 100m2. The success of research on large-scale fingerling breeding technology has made it possible to shorten the breeding cycle of the head catfish to two years, which is of great significance for stabilizing conventional fish production and raising the profit of traditional aquaculture.
