摘要
为更好地保护和开发祁连山裸鲤这一珍稀濒危土著鱼类,总结了培育祁连山裸鲤苗种的关键技术。孵化的鱼苗上浮开口后经5个月左右的培育,苗种平均体长达到9.0 cm,平均体重达到10.6 g,实现祁连山裸鲤苗种的规模化培育,大规格苗种产量达到20万尾/年。
In order to improve the protection and development of Gymnocypris chilianensis,a rare and endangered indigenous fish,the key techniques for seedling rearing of G.chilianensis were summarized.After about 5 months of breeding,the average body length and weight of the hatchling reached 9.0 cm and 10.6 g.The large-scale cultivation of G.chilianensis seedlings was realized,and the output of large-size seedlings reached 200,000 per year.
