环境胁迫(Environmental stress)指鱼类所处的外界环境对其生存状态产生的压力,胁迫能打破鱼类与环境之间的平衡与协调,引发鱼体正常生理机能出现紊乱。鱼类是水生低等变温脊椎动物,容易受外界环境的影响。通过环境胁迫对鱼类生理机能影响的过程与机制的研究,以期为集约化健康养殖技术的建立提供参考依据。 Environmental stress refers to the pressure exerted by the external environment on the living conditions of the fish. Stress can break the balance and coordination between the fish and the environment and lead to disorder of the normal physiological functions of the fish. Fish are low water temperature change vertebrates, vulnerable to the external environment. Through the study of the process and mechanism of the impact of environmental stress on the physiological function of fish, with a view to provide reference for the establishment of intensive healthy breeding technology.
