The domestic fish farming industry is gradually developing a single-sex cultivation approach. As they grow to maturity, fry in the ponds cannot breed, controlling the number of individual fish in each pond, and making physical growth of individuals more uniform.
此外，國內的養殖漁業也逐步發展出單性養殖法，魚苗在魚塭的成長過程中不能交配，魚塭中的尾數獲得控制，魚體成長的速度趨於一致。
