Abstract:

To improve the water quality, the fishery multiplication and the restoration of ecological environment, the application of EM bacteria has attracted extensive attention and become a research hotspot in recent years. This study systematically reviewed the definition and source of EM bacteria, the effect and mechanism of EM bacteria in aquaculture in recent decades, and elaborated the factors affecting the effect of EM bacteria. It is found that: EM bacteria have significant effects on regulating microbial ecological structure, reducing harmful substances in water environment, improving immunity, gaining weight and increasing yield; however, the basic theoretical research of EM bacteria technology is still relatively weak, and there are still deficiencies in the production technology and application process. Therefore, in the future, it is necessary to improve production technology, establish and improve screening system, and develop new fields of research and application of EM bacteria in aquaculture, so as to create greater economic value for aquaculture and provide the possibility for sustainable aquaculture.

Key words: EM bacteria, aquaculture, aquatic environment, microflora, action mechanism, multiplication
