水产养殖与有毒有害污染物残留及其环境影响

文章介绍传统养殖模式虽然有着良好的环境效益,但养殖产量比较低下,不能满足市场需求;现有水产养殖模式养殖结构简单,过度依赖化学农用品的调控,饲料添加剂、生长促进剂、杀虫剂、抗生素等各种化学品的频繁而广泛使用,极大地阻碍了水产养殖业的可持续发展,要降低水产养殖对环境的负面影响,减少水产品中有毒有害物质的污染,必须调整现有的养殖模式,吸收传统水产养殖业中多元化、多层次特点和现代养殖模式中的集约化、规模化特点,摈弃高消耗、高污染的发展模式,合理使用农用化学品,控制养殖水体的污染,发展绿色水产品生产,走可持续发展的道路,这是未来水产养殖业发展的必然方向。

Aquaculture and the Residues of Environmental Xenobiotics and Its Impacts Upon Aquatic Environment

Traditional aquaculture model is often characterized with harmonious environmental effects but yield low output of aquatic production.High output could be obtained from modern aquaculture model which were generally relied upon the control of man-made substances and various medicines,accompanying with many adverse impacts upon environment.Pesticide,antibiotic,feedstuff additive and growth accelerant were widely used in the aquaculture,the frequent use of these chemical materials for a long time in aquaculture not only lead to the environment contaminant,but also pose potential risks to aquatic organisms and the consumers.It is necessary for sustainable development of aquaculture to combine the advantages of traditional aquaculture model with modern model and to leave away the way of high consumption and high contamination.It is the future direction for aquaculture to use reasonable agricultural chemical materials and develop green-aquatic aquaculture production.
