鳜鱼生殖生长调控与良种培育技术研究进展

Progress in the studies of mandarin fish reproductive manipulation,growth regulation and breeding technology

鳜鱼分布在东亚国家,是我国主要养殖淡水鱼类,具有重要的经济价值。近年来,随着全基因组测序的完成,鳜鱼生殖生长遗传基础被逐步揭示。研究人员在鳜鱼中开发了性别染色体分子标记,实现了性别控制育种;开展了细胞工程育种,获得多倍体鱼;进行生长选育和饲料驯化,培育出了多个鳜鱼优良新品种。本文结合自己研究团队的工作,对鳜鱼生殖生长调控机制和良种培育技术进行了总结整理,并讨论了遗传育种方法的应用现状,以期为鳜鱼乃至经济鱼类产业的发展提供方向和目标性思考。

The mandarin fish is a freshwater fish distributed in East Asian countries,and is one of the important economic fish in China.In recent years,with the completion of genome sequencing,the genetic basis of reproductive growth of mandarin fish has been gradually revealed.The researchers developed a molecular marker of sex chromosome in mandarin fish to realize sex-controlled breeding.Polyploid fish was obtained by cell engineering breeding in mandarin fish.Several excellent new varieties have been cultivated by growth selection and feed domestication in mandarin fish.Combined with the studies in our research team,this paper summarizes the reproductive and growth regulation mechanism of mandarin fish and improved seed cultivation technology,and discusses the application status of breeding methods,in an effort to provide a direction and thinking for the development of mandarin fish and other economic fish industry.
