摘要： The overuse of drugs in aquaculture and the expansion of aquaculture have resulted in water quality deterioration. Because it was believed that microbial preparation could improve water quality in aquaculture, a new one was developed by using 8 strains (Saccharomyces cere-visiae, Bacillus natto, Bacillus subtilis, Bacillus licheni-formis, Rhodopseudomonas palustris, Lactobacillus casei, Streptococcus faecalis and Candida utilis). The cell nutrients of this new microbial preparation and the change of water quality parameters after applying this preparation were assessed. The results show that the new microbial preparation was rich in nutrition, and could increase dissolved oxygen but reduce chemical oxygen demand and pollutants, such as ammonia nitrogen, nitrite nitrogen, nitrate nitrogen and sulfide in rearing water. The existing research results suggest that the new microbial preparation could be a useful agent for water management in aquaculture.
