镉是一种主要的水体重金属污染物,易对水生生物尤其是鱼类产生毒性作用。就镉对鱼类生理、生化及其代谢、行为、生物分子及其细胞凋亡的影响进行了综述,以便有目的地确定未来的研究方向;同时,一些研究成果对于渔业的养殖和保护具有现实指导意义。 Cadmium is a major heavy metal pollutant in water, and it is easy to produce toxic effects on aquatic organisms, especially fish. The effects of cadmium on the physiology, biochemistry, metabolism, behavior, biomolecules and apoptosis of fish were reviewed in order to determine the future direction of research purposefully. At the same time, some researches have realistic effects on the fishery breeding and protection Guiding significance.
