The impact of the living environments on the intestinal microbiota of was studied by analyzing intestinal microbiota diversity, composition, and potential function among wild, domesticated, and cultured groups. The results showed that the fish living in the wild environment exhibited the highest alpha diversity of intestinal microbiota. Intestinal microbial communities in the three groups clustered by living environment, with domesticated and cultured groups showing higher similarity. The dominant phylum in the wild group was Proteobacteria, whereas Fusobacteria and Proteobacteria were the predominate bacteria in the domesticated and cultured groups. RsaHF231, Actinobacteria, Fusobacteria, Cyanobacteria, and Firmicutes were the five key bacteria differentially expressed among the groups. Functional prediction revealed significant variation in the L-cysteine degradation III pathway (PWY-5329) between wild and domesticated groups, and in the vitamin E biosynthesis pathway (PWY-1422) between wild and cultured groups ( < 0.05). These findings highlight the differences in microbiota communities between wild and farmed fish, which are essential for enhancing the cultivation of and for the formulation of specific probiotics and functional feeds.
通过分析野生、驯化和养殖群体中肠道微生物群的多样性、组成和潜在功能，研究了生活环境对[鱼的种类未明确]肠道微生物群的影响。结果表明，生活在野生环境中的鱼肠道微生物群的α多样性最高。三组的肠道微生物群落按生活环境聚类，驯化组和养殖组显示出更高的相似性。野生组中占主导地位的门是变形菌门，而梭杆菌门和变形菌门是驯化组和养殖组中的主要细菌。RsaHF231、放线菌门、梭杆菌门、蓝细菌门和厚壁菌门是各组间差异表达的五种关键细菌。功能预测显示，野生组和驯化组之间L-半胱氨酸降解III途径（PWY-5329）存在显著差异，野生组和养殖组之间维生素E生物合成途径（PWY-1422）存在显著差异（P<0.05）。这些发现突出了野生鱼和养殖鱼微生物群群落的差异，这对于加强[鱼的种类未明确]的养殖以及特定益生菌和功能性饲料的配方制定至关重要。
