在1999年以前,中华鲟基本上都是采取剖腹的方法取卵,为了采卵,亲鱼就牺牲了。研究人员曾试验过手术取卵,可确保产后亲鱼成活,但操作烦琐,术后鱼体康复不够理想。能不能不用手术就采卵呢?他们成功了!活体采卵的成功结束了杀鱼取卵的历史,对亲鱼资源的保护具有特别重要的意义。 Before 1999, Chinese sturgeons basically adopted the method of taking cesarean section to pick up their eggs. In order to pick their eggs, the broodstock were sacrificed. Researchers have experimented with ovulation surgery to ensure the survival of postnatal broodfish, but cumbersome operation, postoperative recovery of fish is not ideal. Can they not ooze without surgery? They succeeded! The success of ovipositing in the living has ended the history of fish-killing eggs and is of particular importance for the conservation of broodstock resources.
