Abstract

Background: Fish gut microbiota undergo dynamic changes under the influence of many factors and play an important role in the nutrition, immunity and development in fish. Although common carp (Cyprinus carpio L.) is an economically important freshwater fish, there are few reports on its gut microbiota changes at different early developmental stages. In the present study, the gut microbiota of common carp during the early developmental stages and its correlation with the feed and pond water flora were studied using the Illumina MiSeq sequencing platform.

Results: The results showed that the gut microbiota of common carp underwent continuous and mild changes over the development process, and the pond water environment might provide bacterial resources and have a certain influence on the changes in the gut microbiota of common carp. However, host selection pressure played a more important role in shaping the gut microbiota. Although the gut microbiota was affected by many factors, the presence of core microbiota indicated that some bacterial species adapt to the gut microenvironment of common carp and played a role in its growth process.

Conclusions: The dynamic changes of gut microbiota of carp in early development stage were related to the feed, water environment and host selection. The results of this study provide a theoretical basis for healthy farming and disease prevention of common carp.

鲤鱼(Cyprinus carpio L.)早期发育阶段肠道微生物群的变化及其与饲料和池水微生物群的相关性。
背景:鱼类肠道微生物群在多种因素的影响下发生动态变化,在鱼类的营养、免疫和发育过程中发挥着重要作用。虽然鲤鱼(Cyprinus carpio L.)是一种具有重要经济价值的淡水鱼,但有关其肠道微生物群在不同早期发育阶段变化的报道却很少。本研究利用 Illumina MiSeq 测序平台研究了鲤鱼早期发育阶段的肠道微生物群及其与饲料和池水菌群的相关性:结果表明,鲤鱼肠道微生物群在发育过程中发生了持续而温和的变化,池塘水环境可能提供了细菌资源,对鲤鱼肠道微生物群的变化有一定影响。然而,宿主的选择压力对肠道微生物群的形成起着更为重要的作用。虽然鲤鱼肠道微生物群受到多种因素的影响,但核心微生物群的存在表明一些细菌种类适应了鲤鱼的肠道微环境,并在其生长过程中发挥了作用:结论:鲤鱼肠道微生物群在发育早期的动态变化与饲料、水环境和宿主选择有关。本研究结果为鲤鱼的健康养殖和疾病预防提供了理论依据。
