在美国,草鱼作为一种有效地控制水草的生物已受到重视。但是人们也一直担心草鱼会从控制水草生长的放养水域逃逸,形成对其它水域中天然鱼类和水禽有害的繁殖种群。为了避免过量的繁殖,放养单性草鱼是一种值得探讨的方法。此外,产生单性草鱼的技术还可用于其它鱼类。

In the United States, grass carp has received great attention as a living creature that effectively controls aquatic plants. However, people have also been worried that grass carp will escape from the stocking waters that control the growth of aquatic plants and form breeding stocks that are detrimental to natural fish and waterfowl in other waters. In order to avoid excessive breeding, stocking grass carp is a worth exploring method. In addition, the technology for producing single-sex grass carp is also available for other fish species.
