淡水螯虾生理生态学与环境毒理学研究进展

Research progress in physiological ecology and environmental toxicology of freshwater crayfish

综述了我国2种主养的淡水螯虾(克氏原螯虾和红螯螯虾)在生理生态学与环境毒理学方面的研究进展。总结了淡水螯虾的环境条件(盐度、温度和pH)适应范围、毒性污染物(氨氮、亚硝酸盐、重金属和农药等)的半致死浓度和安全浓度,以及环境胁迫和毒性污染物暴露对淡水螯虾生长、组织结构、生理代谢和免疫功能等的影响,为淡水螯虾养殖的水环境监测与调控提供参考依据。

Research progress in physiological ecology and environmental toxicology of two cultured freshwater crayfish （ Procambarus clarkii and Cherax quadricarinatus） was reviewed. The suitable range of environmental conditions （salinity, temperature and pH） and the medial lethal concentrations （LC50） and safety concentrations of toxic contaminants （ammonia, nitrite, heavy metals and pesticides） for freshwater crayfish, and the effects of environmental stress and contaminant exposure on growth, organization struc-ture ,physiological metabolism and immunity were summarized. It provides reference for water environment monitoring and regulation of culture of freshwater crayfish.
