The giant river prawn, Macrobrachium rosenbergii, is an economically important freshwater prawn. The cultivation of zoea larvae is crucial for the success of the M. rosenbergii industry. In this study, we surveyed the microbial community diversity and structure associated with M. rosenbergii zoeae at different stages of larval development. Samples of zoea larvae from different developmental stages were collected and subjected to high-throughput DNA sequencing. Firmicutes, Proteobacteria, Bacteroidetes and Actinobacteria were the dominant phyla in all six sample groups. At the genus level, the relative abundance of Bacillus decreased, and that of Enterobacter increased with the growth of the zoeae. This may have been related to the intestinal development of the zoea larvae. The microbial diversity of M. rosenbergii zoea larvae decreased significantly with development. The beta diversity analysis showed that the closer the developmental stage of M. rosenbergii, the more similar the structure of the associated bacterial communities.

在整个幼体发育过程中，与罗氏沼虾（Macrobrachium rosenbergii zoeae）相关的微生物群落的组成各不相同。

巨大的河虾罗氏沼虾是经济上重要的淡水虾。zoea幼虫的栽培对于罗氏沼虾工业的成功至关重要。在这项研究中，我们调查了在幼虫发育不同阶段与罗氏沼虾相关的微生物群落多样性和结构。收集了不同发育阶段的zoea幼虫样品，并对其进行了高通量DNA测序。在所有六个样品组中，硬毛菌，变形杆菌，拟杆菌和放线菌是主要的门。在属水平上，芽孢杆菌的相对丰度降低，而肠杆菌的相对丰度随着细菌的生长而增加。这可能与zoea幼虫的肠道发育有关。M.的微生物多样性 罗氏沼虾幼虫随着发育而显着下降。β多样性分析表明罗氏沼虾的发育阶段越近，相关细菌群落的结构越相似。
