【摘要】 罗非鱼类作为重要的水产养殖品种,耐受低温能力差成为限制其产量的重要原因。因此,很多学者对低温伤害罗非鱼的机理进行了多方面的研究,以期针对性地解决罗非鱼不耐寒的问题。文章综述了饵料、环境和鱼体自身等影响罗非鱼耐寒的因素,以及低温对鱼体的伤害范围,包括宏观的生理变化和微观的细胞分子水平的改变,介绍了低温对罗非鱼的影响及相关机理研究,重点讨论了这些研究成果的重要指导意义。更多还原

【Abstract】 Tilapia,as an important aquaculture species,has poor tolerance to cold,which severely restrains the yield of this species.Therefore,the mechanism of cold injury to tilapia has been studied from different angles in order to solve this problem.The paper summarizes the factors which affect the cold resistance of tilapia such as diet,environment and physiological conditions of the fish,reviews its cold injury including macroscopic physiological alternation and microscopic changes in the levels of cell and molecular.Moreover,it introduces the effect of low temperature on tilapia as well as relevant studies,and discusses their significant inspiration.更多还原
