| 摘 要： | 中华绒螯蟹(Eriocheir sinensis)繁育亲蟹规格及其子代的生产性能是其产业上的热点问题。本研究应用个体生长测定法和代谢组学技术，研究了当前生产上3种主要育苗亲蟹规格（母本200~250g，父本300~350g；母本250~300g，父本350~400g；母本300g以上，父本400g以上）繁殖子代（规格A、规格B和规格C）的蜕壳与生长特性、肠道微生物菌群和肝胰腺代谢物的组成差异。结果发现：在2次个体蜕壳与生长测定中，规格C的生长性能优于其他两种规格，但3种规格子代相互间的蜕壳增重率、蜕壳间隔、肥满度、肝胰腺指数和肌肉指数均不存在显著差异。肠道菌群结果表明：α多样性指数均显示规格A低于其他两种规格，但3规格相互间无显著差异，而主坐标分析（PCoA）显示3种规格肠道菌群在属水平上存在显著差异。肝胰腺的代谢组学分析显示，规格A与B间共有100种差异代谢物，规格B与C间共有77种差异代谢物，规格A与C间共有79种差异代谢物。对差异肠道菌群和差异代谢物进行Pearson相关性分析发现：规格A的代谢物生物喋呤与副梭菌属呈显著正相关；规格B的代谢物N-乙酰-D-甘露糖胺分别与硝基螺菌门、硝化螺菌属呈显著负相关；规格C的代谢物四氢二吡啶甲酸盐与乳酸菌属呈显著负相关。本研究结果初步表明：不同亲蟹规格子代在生长性能、肠道微生物菌群和肝胰腺代谢物组成方面表现出一定差异。
