西充县实施黄鳝资源保护与人工增殖措施后,黄鳝的天然产量提高了2 6倍,稻田人工增殖黄鳝后,产量是天然产量的9 8倍。黄鳝资源的可持续增长,单纯依靠资源保护和人工增殖是不够的,还要依靠黄鳝种群数量的大幅增加。只有实现黄鳝苗种人工繁育的规模化、商业化,才能从根本上实现黄鳝资源可持续增长,才能使黄鳝增殖、养殖更具有实际意义。
After implementing the resource conservation and artificial propagation measures of eel in Xichong County, the natural output of eel increased by 26 times. After artificial propagation of rice field, the yield of eel was 98 times of the natural output. Eel resources, sustainable growth, relying solely on resource protection and artificial proliferation is not enough, but also rely on the substantial increase in the population of eel. Only the realization of artificial breeding of eel seed large-scale, commercial, in order to fundamentally achieve sustainable growth of eel resources in order to make the eel proliferation, breeding more practical significance.
