鱼类精液冻结保存研究,是从1953年布拉库斯塔尔的鲱鱼精液保存半年并且成功授精开始的。其后此法试用于鲑科鱼类、海产鱼及鲤科淡水鱼类等,目前几乎所有鱼类精液都有进行冻结保存的可能。鱼类,特别是鲑科鱼类雌雄性成熟期有时相差数周,给育苗生产带来了障碍。尤以大麻哈鱼、马苏大麻哈鱼为严重。在育苗上一般只好采取用长日电照处理雄鱼来推迟精子成熟期以待和成熟卵授精的方法。 Fish semen freeze preservation studies began with the preservation of herring semen in Bulangshushu in 1953 for six months and successful insemination. Since then, this method has been applied to salmonids, marine fish and carp freshwater fish. At present, almost all fish semen have the possibility of frozen preservation. The males and females, especially salmonids, sometimes differ in sexual maturity for several weeks, creating barriers to nursery production. Especially salmon, Masu salmon is serious. In nursery on the general had to take long daylight treatment of male fish to delay the maturation of mature and mature eggs to be fertilized methods.
