在自然条件下,锦鲤排精、产卵不太同步,受精卵的孵化率及苗种成活率极低,导致大批量人工养殖时苗种不足。我们经过两年的摸索、研究,通过人工催产,加强苗种培育,解决了这一难题。现将有关技术总结如下。1 人工催产1.1 亲鱼的选择 一般是在干池并塘过冬之前进行,选择
Under natural conditions, Koi pollination, spawning is not synchronized, the hatching rate of fertilized eggs and seedling survival rate is extremely low, resulting in large-scale artificial breeding shortage of seedlings. After two years of exploration and study, we have solved this problem through artificial spawning and nurturing seed cultivation. Now the technology is summarized as follows. 1 Artificial birth 1.1 The choice of broodstock is generally carried out in the dry pool and pond before the winter, choose
