Abstract: With the expansion of the scale of the cultivation of sea cucumber, many problems in the cultivation gradually become prominent. In the process of sea cucumber cultivation, pollutants such as residual bait excrement and other pollutants produce toxic ammonia nitrogen and nitrite, which can lead to the decline of water quality and seriously reduce the yield of sea cucumber. The disease caused by pathogenic microorganism directly threatens the economic benefit of aquaculture. Despite the strengthening of fishery resources and environmental protection, the disease of sea cucumber breeding still occurs frequently, and the disease is mainly traced back to microorganisms. Therefore, this paper summarized the formation and host regulation of intestinal microorganisms of sea cucumber, and introduced the early colonization, function and regulation of intestinal microorganisms, providing a reference for understanding the formation mechanism of intestinal microorganisms of sea cucumber as well as the prevention and treatment of related diseases.

Key words: sea cucumber, pathogenic microorganisms, disease, function
