缺氧胁迫及对贝类免疫系统的影响

人为压力源的强度和多样性日益增加已引发全球海洋生态系统中栖息地和生物多样性丧失。与全球变暖、海洋酸化类似,海域缺氧现象的频发使得缺氧现象成为重要的全球压力源。本文以贝类为研究对象,综述了缺氧的定义和等级、缺氧的原因,并集中探讨了缺氧胁迫对贝类免疫系统的影响,以期为贝类养殖和病害防治提供理论依据,并为我国贝类产业能够及时应对未来环境变化提供参考资料。

Hypoxia Stress and Its Effects on Immune System of Shellfish

The increasing intensity and diversity of anthropogenic stressors have triggered the loss of habitat and biodiversity in global marine ecosystems.The occurrence and development of coastal hypoxia and anoxia have become a global key stressor to marine ecosystems,and also the consequences of human activities,just like global warming and ocean acidification.This paper takes shellfish as the research object,and reviews the definition of hypoxia,the grade of hypoxia and the causes of hypoxia.We focus on the effects of hypoxia stress on the immune system of shellfish,so as to provide a theoretical basis for shellfish cultivation and disease control,and provide data for the shellfish industry in China to timely respond to future environmental changes.
