Water quality parameter dynamics, gut, sediment and water bacteria communities were studied to understand the environmental influence on the gut microbial community of a new strain of Huanghe common carp. A total of 3,384,078 raw tags and 5105 OTUs were obtained for the gut, water and sediment bacteria. The water quality had a stronger influence on the water bacteria community than gut and sediment bacteria communities. The ambient water quality parameters also significantly influenced the water and sediment bacteria communities. Comparing the gut, sediment, and water microbial communities, a relationship was found among them. However, gut bacteria were more closely related to sediment bacterial communities than to water bacteria communities. The results showed that the top three bacterial taxa were identical in gut and sediment samples in the early days of rearing. Interestingly, bacterial communities in the carp gut, water, and sediment had different adaptabilities to variations in environmental factors.
为了解环境对黄河鲤新品系肠道微生物群落的影响，研究了水质参数动态、肠道、沉积物和水体细菌群落。肠道、水体和沉积物细菌共获得3384078个原始标签和5105个操作分类单元。水质对水体细菌群落的影响比对肠道和沉积物细菌群落的影响更大。环境水质参数也显著影响水体和沉积物细菌群落。比较肠道、沉积物和水体微生物群落，发现它们之间存在一定关系。然而，肠道细菌与沉积物细菌群落的关系比与水体细菌群落的关系更密切。结果表明，在养殖初期，肠道和沉积物样本中的前三大细菌类群相同。有趣的是，鲤鱼肠道、水体和沉积物中的细菌群落对环境因子变化具有不同的适应性。
