生态修复剂在水产养殖中的应用试验

Application Test on Ecological Restoration in Aquaculture

根据2006年北京渔业环境监测报告,北京市高度集约化的养殖方式造成养殖水体污染严重,水体中非离子氨、总氮、COD等指标存在着不同程度的超标现象。水体环境污染所引发的这一系列问题,已阻碍了水产养殖的可持续性、健康发展。作者对微生态制剂(生态修复剂)净化养殖水体技术进行了试验,试验面积2.8hm2,取得了很好的经济效益。试验渔场在养殖季节基本不用换水,对于节约北京市水资源有重要意义。水体环境的改善降低了鱼病的发生率,特别是生态修复剂的使用可以显著抑制细菌性鱼病的发生,从而减少甚至避免抗生素类药物的使用,大大提高了水产品的质量安全。因此,具有显著的社会、生态效益,极具推广前景。

According to the 2006 Beijing Fisheries Environment Monitoring Report, Beijing highly intensive farming methods that result in serious pollution of water for aquaculture, water non-ionic ammonia, total nitrogen, COD and other indicators of the existence of different degrees of excessive behavior. Water pollution caused by this series of problems has hindered the sustainability of aquaculture and healthy development. The author of probiotics (ecological restoration agent) water purification technology for culture experiments, testing an area of 2.8 hm2, achieved good economic results. Test fisheries in the breeding season, basically do not change the water for the conservation of water resources, Beijing has important significance.The improvement of water environment reduces the incidence of fish diseases, in particular the use of ecological restoration agent can significantly inhibit the incidence of bacterial fish diseases, thus reducing or even avoiding the use of antibiotic drugs has greatly improved the quality and safety of aquatic products. Therefore, has significant social and ecological benefits, great promotion prospects.
