摘要: 早期认为鱼类肠道中存在寥寥可数、结构简单的微生物群落,随着鱼类肠道微生态学的发展,人们逐渐认识到鱼类肠道中存在着种类繁多、数量庞大的微生物群落。复杂的生活环境、不同的发育阶段、多变的食物来源等因素都会导致鱼类肠道微生物多样性及结构发生变化。鱼类肠道微生物与栖息环境所形成的微生态系统在保持动态平衡时,能够维持宿主的肠道健康。大量研究显示稳态中的微生态系统能够调节肠道微生物群落的平衡、改善肠道微生物群落的组成,从而对鱼类生长发育、营养代谢、免疫调控等过程具有促进作用。本文综述了鱼类肠道微生物的研究方法、多样性和功能,总结了温度、盐度及水体饵料等环境因子对鱼类肠道微生物的影响,以期为今后鱼类肠道微生物的研究发展提供启发和参考。

Abstract: In the early days, it was thought that there were few simple microbial communities in the fish gut, but with the development of fish gut microecology, it was gradually recognized that there were a large number of diverse microbial communities in the fish gut. Complex living environments, different developmental stages, and variable food sources can lead to changes in the diversity and structure of fish gut microorganisms. The microecosystem formed by fish gut microbes and their habitat is able to maintain the host's gut health when it is in dynamic balance. Numerous studies have shown that microecosystem in homeostasis can regulate the balance of gut microbial communities and improve the composition of gut microbial communities, thus promoting fish growth and development, nutrient metabolism, immune regulation and other processes. This paper reviewed the research methods, diversity and functions of fish gut microorganisms, and summarized the effects of environmental factors such as temperature, salinity and food in water on fish gut microorganisms, in order to provide inspiration and reference for future research development of fish gut microorganisms.

Key words: fish, gut microorganisms, environmental factors, diversity, function
