在养殖池塘中使用生物制剂,能分解池中有机污染,优化水质和底质,抑制病原菌,增强免疫力,降低发病率,提高产量、品质和效益,对发展健康养殖、生态养殖,保障水产品质量安全都具有十分重要的意义。应用于水产养殖上的生物制剂按用途可分为两大类:一类是内服的饲料生物添加剂,如乳酸菌、芽孢杆菌、酵母菌等;另一类是改良水质的生物调控剂,如光合细菌、EM菌、硝化细菌 The use of biological agents in aquaculture ponds can break down organic pollution in ponds, optimize water quality and sediment, inhibit pathogens, enhance immunity, reduce morbidity, increase yield, quality and benefit, and play an important role in developing healthy aquaculture, ecological farming and aquaculture Quality and safety are of great significance. Biologics used in aquaculture can be divided into two categories according to their uses: one is a feed biological additive administered orally, such as lactic acid bacteria, bacillus, yeast, and the like; and the other is biological regulating agents for improving water quality, such as photosynthetic bacteria , EM bacteria, nitrifying bacteria
