为了保护长江特有的中华鲟鱼资源,水产科研人员正在积极开展捕捞运输和人工繁殖等保护措施的试验研究。试验证明(1)用流刺网捕捉和活水运输等方法可以保证被捕的中华鲟鱼不受伤,网捕过坝作为施工期间的过渡措施是可行的。(2)在坝下江段可以捕获性腺发育到Ⅳ期的成熟亲鱼,用人工繁殖放流的方法可保护和发展中华鲟鱼资源。
In order to protect the sturgeon resources unique to the Yangtze River, aquaculture researchers are actively carrying out experimental studies on protective measures such as fishing, transportation and artificial breeding. Experiments show that (1) catching stinger and living water transport methods can ensure that the stranded Chinese sturgeon is not injured, catching the dam as a transitional measure during the construction is feasible. (2) Mature gonads can be caught in the downstream section of the dam from the gonad to stage IV, and the artificial sturgeon can be used to protect and develop the Chinese sturgeon resources.
