A 30-day feeding investigation was conducted to resolve the effects of starvation in juvenile loach (Paramisgurnus dabryanus). In this study, the digestive enzyme activity, antioxidant activity, immune enzyme activity, and microflora compositions were analyzed to investigate the effects of starvation. At the end of the 30-day trial, loaches in the feed and starved groups were sampled for enzyme activities and microflora analysis. Results revealed that the superoxide dismutase (SOD) and catalase (CAT) activities increased significantly in the starved group than in the feed group. Starvation was also observed to lower the digestive enzymes activities and improve the immune system of loach. Additionally, the findings of this study indicated that starvation greatly affected the abundance of different bacterial phyla in the two groups. Proteobacteria (57.14 %), Firmicutes (12.79 %), and Bacteroidetes (7.41 %) were the dominant phyla found in the feed group, while Proteobacteria (35.56 %), Bacteroidetes (35.01 %), and Firmicutes (9.56 %) were the dominant phyla found in the starved group. Clearly, starvation disturbed this fish’s immune system, and nourishment, in turn, affected gut microbiota. This study involved a comprehensive investigation on the synergism among intestinal microorganisms and hosts under changing conditions. These findings will enhance our knowledge on how intestinal microbiota and hosts react with their dynamic surroundings and will serve as an important resource for future studies.

进行了为期30天的喂养调查，以解决饥饿对幼年泥ach（Paramisgurnus dabryanus）。在这项研究中，分析了消化酶活性，抗氧化活性，免疫酶活性和微生物区系组成，以研究饥饿的影响。在30天的试验结束时，对饲料组和饥饿组的泥were取样进行酶活性和菌群分析。结果表明，饥饿组的超氧化物歧化酶（SOD）和过氧化氢酶（CAT）活性显着高于饲料组。还观察到饥饿降低了消化酶的活性并改善了泥ach的免疫系统。此外，这项研究的结果表明饥饿严重影响了两组中不同细菌门的数量。饲料组中主要的菌群是细菌杆菌（57.14％），菌毛菌（12.79％）和拟杆菌属（7.41％），在饥饿的人群中，主要的菌群有杆菌属（35.56％），拟杆菌属（35.01％）和硬毛菌（9.56％）。显然，饥饿会扰乱这条鱼的免疫系统，而营养又会影响肠道菌群。这项研究包括对不断变化的条件下肠道微生物与宿主之间协同作用的全面研究。这些发现将增强我们对肠道微生物群和宿主如何与其动态环境发生反应的知识，并将作为未来研究的重要资源。这项研究包括对不断变化的条件下肠道微生物与宿主之间协同作用的全面研究。这些发现将增强我们对肠道微生物群和宿主如何与其动态环境发生反应的知识，并将作为未来研究的重要资源。这项研究包括对不断变化的条件下肠道微生物与宿主之间协同作用的全面研究。这些发现将增强我们对肠道微生物群和宿主如何与其动态环境发生反应的知识，并将作为未来研究的重要资源。
