Little is known about the functions of the crustacean gut microbiome, but environmental parameters and habitat are known to affect the composition of the intestinal microbiome, which may in turn affect the physiological status of the host. The mud crab Scylla serrata is an economically important species, and is wild‐caught, and farmed across the Indo‐Pacific region. In this study, we compared the composition of the gut microbiome (in terms of gut microbial species richness and abundance) of S. serrata collected from wild sites, and farms, from the east and west coast of India, and also tested the effects of the environment on the composition. The water temperature had a statistically significant effect on gut microbiome composition, with microbial biodiversity decreasing with increasing water temperature. This could have negative effects on both wild and farmed mud crabs under future climate change conditions, although further research into the effects of temperature on gut microbiomes is required. By comparison, salinity, crab mass and carapace width, geographical location as well as whether they were farmed or wild‐caught crabs did not have a significant impact on gut microbiome composition. The results indicate that farming does not significantly alter the composition of the gut microbiome when compared to wild‐caught crabs.

南印度锯缘青蟹肠道细菌群落的比较分析
对甲壳类动物肠道微生物组的功能知之甚少，但已知环境参数和栖息地会影响肠道微生物组的组成，进而可能影响宿主的生理状态。泥蟹Scylla serrata是一种具有重要经济意义的物种，在印度-太平洋地区是野生捕捞和养殖的。在这项研究中，我们比较了锯缘锯缘青蟹的肠道微生物组的组成（就肠道微生物物种丰富度和丰度而言）从印度东海岸和西海岸的野外和农场收集，还测试了环境对成分的影响。水温对肠道微生物组的组成有统计学意义的影响，微生物的生物多样性随着水温的升高而减少。在未来的气候变化条件下，这可能对野生和养殖的泥蟹产生负面影响，尽管需要进一步研究温度对肠道微生物群的影响。相比之下，盐度、螃蟹质量和甲壳宽度、地理位置以及是否养殖或野生捕捞的螃蟹对肠道微生物组组成没有显着影响。结果表明，与野生捕捞的螃蟹相比，养殖不会显着改变肠道微生物组的组成。
