摘    要:水产种质资源是水产业持续、健康、稳定发展的重要物质基础,培育出优质、高产、高效的新品种是保障养殖业可持续发展的关键。鱼类的生长速度是评价养殖价值的重要指标,也是选育的重要性状之一,然而鱼类育种的基础薄弱,鱼类品种改良的理论基础和技术创新一直困扰着鱼类育种工作。本文从内因(遗传等)和外因(食物、温度、溶氧及种内种间关系等)两方面探讨了各因子对鱼类生长的影响,依此就鱼类生长性状的调控策略进行了述评,并对其做了展望,以期为鱼类生长性状的改良及其调控提供理论依据和指导。

关 键 词:鱼类  生长性状  调控策略

Abstract:Fishes germplasm resources provide essential material foundation for sustainable,healthy and stable aquaculture.The new strain or species with the good quality,high nutrient and efficiency as well as high yield are the keys to promote the sustainable development of aquaculture.Fish growth rate is an important index for evaluating the breeding values,which is also one of the important breeding traits in practice.Yet the fish breeding foundation is poor,the improvement theoretical basis and technology innovation has been plagued the fish breeding work.In order to provide theoretical basis and guidance to improve the growth traits and regulation,effects of internal factors(genetic,physiology) and external factors(food,temperature,oxygen and species relationships,etc.) on growth were discussed,based on the strategy of fish growth traits regulation and improvement were reviewed.
Keywords:fish  growth traits  regulation
