Abstract： Microecological preparation is a kind of natural and environmental protection preparation. It has many advantages， such as non-toxic side effects， no drug residues， no drug resistance， etc. and has been widely used in aquaculture. The types， action mechanism， application methods of the microecological agents in aquaculture were reviewed in this paper. The problems existing in the application of probiotics and the development direction in the future were also discussed， in order to provide theoretical basis for the rational use of aquatic microecological agents.

高密度养殖产生的大量残饵及水产动物代谢产物对养殖环境造成了严重污染，导致养殖水域生态功能退化，养殖动物病害频发，而滥用抗生素易使病原菌产生抗药性，而抗生素残留也会影响水产品品质，这些最终都会给养殖户造成损失[1]。（剩余3963字）
