鱼类育种技术研究进展

鱼类育种技术讨论进展摘 要：我国海淡水鱼类近 5000 种，其中海水鱼约占三分之二，淡水鱼约占三分之一，鱼类养殖种类数由 60 年代的十多种增加到目前的百种左右，养殖产量也得到相应提高。建立先进的鱼类育种技术体系和育种讨论创新平台、提高鱼类遗传育种的效果和种苗质量对促进水产养殖业的健康进展具有重要意义。本文阐述了鱼类遗传育种的技术及其当前的进展动态，分析了现代生物技术在鱼类育种中的应用概况，探讨了鱼类遗传育种的进展趋势，旨在为鱼类新品种选育提供理论依据与参考。关键词：鱼类；育种；技术；讨论进展Progress in Fish Breeding TechnologyAbstract：Freshwater fishes of the sea of nearly 5,000 species, of which about two-thirds of marine fish, freshwater fish account for about one-third of the number of types of fish farming dozen 1960s to the current hundred or so, aquaculture production also increased accordingly. Establishment of advanced technology systems and breeding fish breeding research and innovation platform to improve the effectiveness and quality of fish breeding seedlings to promote the healthy development of the aquaculture industry is important. This paper describes the technology and its current developments fish breeding, and analyzes the application of modern biotechnology in fish breeding overview discusses trends in fish breeding, fish breeding new varieties designed to provide theoretical basis and reference.LRWN4TM。Key words: Fish; Breeding; Technology; Progress近年来，我国的渔业产量和养殖规模一直居世界首位，但从总体上来看，依旧需要高效、优质、抗病力强的养殖品种。纵观世界水产行业都因良种的突破性成果而得到了提高和进展，而水产养殖发达国家，良种繁育和品种改良也都被列为重要的讨论课题，所以通过传统育种和现代生物技术对鱼类进行品种选育和遗传改良，获得具有优良性状的优质苗种，对促进水产养殖业向高产、优质、持续、健康方向进展具有重要意义[1]。5HiYDeM。早在公元前 9000 年左右人类就开始驯化野生动物，但直到公元 1750 年之后才开始进行现代意义上的动物...
