近几年来,水产养殖集约化高密度养殖规模扩大,养殖生态环境恶化,导致病原微生物种类增多和传播速度加快。与此同时盲目用药导致病原微生物的抗药性增加,病害问题日渐严重。怎样才能够保持水产养殖健康、稳定的发展,日益为人们所关注,在生产实践中我们发现利用微生态制剂建立单个养殖池塘良性生态循环系统,不但可改善养殖生态环境,提高养殖生物免疫力,而且可减少疾病发生, 维持养殖环境的生态平衡。微生态制剂又称生态调节剂,它是在微生态学理论指导下,从天然环境中分离的有益微生物,经特殊工艺加工制成的富含细菌菌体及代谢产物的活菌制剂。 In recent years, aquaculture intensive high-density aquaculture has expanded in scale and the ecological environment of aquaculture has deteriorated. As a result, the number of pathogenic microorganisms has increased and the speed of communication has been accelerated. At the same time, blind drug use leads to increased resistance of pathogenic microorganisms and worsening of disease problems. How to keep the healthy and steady development of aquaculture is paid more and more attention. In the production practice, we found that the use of probiotics to establish a benign ecological cycle system of single aquaculture pond can not only improve the ecological environment for breeding, But also reduce the incidence of diseases and maintain the ecological balance of farming environment. Microecology is also called ecological regulator. It is a kind of viable microbe that is made from special microorganism, which is isolated from natural environment under the guidance of microecology theory.
