水产用微生态制剂的研究进展及存在问题

介绍了微生态制剂在水产养殖中的作用机制、研究进展,以及当前应用中的主要问题,并展望了今后的发展前景.微生态制剂在水产动物中的作用机理,包括优势种群理论、膜菌群或屏障作用理论、“三流运转”理论、生物夺氧理论和正常菌群与营养关系理论等.在水产养殖的应用中,主要从改善水质、促进生长和增强免疫3方面来进行分析.而生产实践中微生态制剂也存在诸多问题,如应用规范、品种质量、检测技术等方面.但微生态制剂仍然是抗生素最有潜力的替代品,具有广阔的应用前景.

With Aquatic Mmicroecologics Research Progress and the Existing Problems

This article introduces the microecologics in aquaculture mechanism,research progress,as well as the current major problems in application,and looks forward to the prospect of development in the future.Microecologics in aquatic animals,the mechanism of including the dominant population theory,film bacterium group or barrier function theory,three kind of flow operation of the theory,biological took oxygen theory and normal flora and nutrition relationship theory,etc.Aquaculture application,mainly from improvement of water quality,promote the growth and strengthen the immune three aspects to analysis.Production of microecologicl preparation in aquaclture also has many problems,such as application of varieties,quality standard,testing technology,etc.But microecologics is still the most potential substitute antibiotics,and has the broad application prospect.
