大黄鱼种质资源保护与利用现状及建议

Protection and utilization status and prospect of large yellow croaker (Larimichthys crocea) germplasm resources

  • 摘要: 优异种质资源的发掘利用对保障我国优质水产蛋白供给具有关键作用。大黄鱼是我国海水鱼类养殖产量最高的品种,种质资源是大黄鱼养殖产业健康和可持续发展不可或缺的物质基础,系统开展大黄鱼种质资源收集保存、鉴定评价和保护利用具有十分重要的战略意义。本文回顾了大黄鱼种质资源保护和开发利用的历史与现状,从科研、育种技术体系、产业和人才等方面剖析了当前面临的主要问题,围绕大黄鱼种业科技创新和新品种创制主线,提出了针对复杂经济性状 (如抗病、抗逆和饲料利用效率等)创制重大新品种的发展方向,为实现大黄鱼良种覆盖率的显著提升,以及大黄鱼产业健康发展提供良种保障。

     

    Abstract: The excavation and utilization of excellent germplasm resources are pivotal in ensuring the supply of China’s high-quality aquatic protein. As Larimichthys crocea owns China’s highest production in marine aquaculture, and its germplasm resources serve as an indispensable material basis for the healthy and sustainable development of L. crocea breeding industry, it is of great strategic significance to carry out the collection, preservation, identification, evaluation, protection and utilization of L. crocea germplasm resources systematically. This paper has reviewed the history and present situation of germplasm protection and utilization of L. crocea, and analyzed the main current problems from the aspects of scientific research, breeding technology system, industry, and talents. Besides, based on the scientific and technological innovation of L. crocea seed industry and the creation of new varieties, the development direction creating major new species with such traits as disease resistance, stress resistance, high yield, high quality, and high compound feed conversion ratewas proposed to substantially expand the coverage of improved L. crocea and provide a fine bread guarantee for the healthy development of L. crocea industry.
