由于工业“三废”、城市生活污水、医用污水等污染物的大量排放,全球气候的异常变化,水产养殖业的自身污染以及水资源的日益紧缺等原因,使得我国水产养殖业水质恶化问题日趋严重,从而在一定程度上限制了我国水产养殖业的健康发展,引发了水产养殖产品的质量安全问题。有益微生物制剂对养殖水产品无毒副作用,无药物残留,对病原菌不产生抗药性,可用来净化水质、改善养殖生态环境、作为饲料添加剂等广泛使用;作为一种运用日益广泛的水产养殖用品,不少养殖者对有益微生物的概念、组成、作用机理以及在水产养殖上的使用方法还存在疑问,为此本刊特组编了一组有关的稿件,希望能对养殖者起到指导的作用。 Due to the industrial “three wastes”, large-scale discharge of urban domestic sewage, medical sewage and other pollutants, the abnormal changes in the global climate, aquaculture itself pollution and the growing shortage of water resources and other reasons, making China’s aquaculture water quality deterioration Which is more and more serious, which limits the healthy development of aquaculture in our country to a certain extent and raises the quality and safety of aquaculture products. Beneficial microorganism preparations have no toxic and side effects on aquaculture products, no drug residues and no resistance to pathogenic bacteria. They can be used to purify water and improve the ecological environment for breeding and are widely used as feed additives. As a widely used aquaculture product, Many farmers still have questions about the concept, composition, mechanism of action of beneficial microbes and their use in aquaculture. To this end, we have compiled a set of relevant manuscripts in the hope that they will play a guiding role for farmers .
