摘要
海水网箱养殖系统是一种高密度、高投饵的非自然人工养殖生态系统，其投入的饵料，输出的废物及代谢物封沉积环境产生了一系列直接或间接的影响。主要污染影响因素包括有机质、化学制剂和营养盐等直接影响因素；溶解氧、硫化物、底质厚度增加等间接影响因素。追入沉积物申的污染物质在生物、化学和物理作用下会重新追入水体造成二次污染，有些污染物还会通过食物链富集到海洋水产品体内，进而威胁人类健康。本文对近期国内外的相关研究进行了综述，阐述了上述研究的海洋学意义及社会效益，并封研究的重点作了展望。
The growing marine cage culture has brought high pressure to the marine ecological environmental protection. Marine cage culture is a high-density and unnatural artificial culture ecosystem. The feed put in it and the waste matter and metabolites output of it have a series impacts on the sedimental environment. The main polluting factors including organic matter, chemicals and sulfide pollutants were discussed. The pollutants may diffuse into the water column again and cause eutrophication. Some pollutants accumulate in the sea food and threaten people＇s health. Then, the oceanographic significance and social benefits of the studies were expounded and the future of main research and key problems were forecasterd.
