Male play an important role in aquaculture and consumption, yet their regional nutritional traits are underexplored. This study compared wild males from five southeast China regions, including Nansha (GNS), Qisha (GQS), Zhangzhou (FZZ), Taizhou (ZTZ), and Danzhou (HDZ), analyzing proximate composition, fatty acids, amino acids, and minerals. Results showed HDZ muscle had the highest crude protein, while FZZ hepatopancreas had the highest crude lipid ( < 0.05). Muscle tissues were rich in essential amino acids, with ZTZ having the highest concentration (190.09 mg/g). GNS hepatopancreas exhibited the highest DHA (10.87 %) and n-3/n-6 PUFA ratio (3.59), whereas HDZ showed the highest EPA (7.85 %). The copper concentration in GNS hepatopancreas was the highest (546.28 mg/kg), suggesting the need for intake limitations. Comparison with females revealed significant sex-related nutritional differences. These findings highlight notable regional variation in male mud crab nutritional profiles, emphasizing their value for human nutrition and aquaculture development.
雄性在水产养殖和消费中发挥着重要作用，但其区域营养特性尚未得到充分研究。本研究比较了中国东南部五个地区的野生雄性个体，包括南沙（GNS）、七沙（GQS）、漳州（FZZ）、台州（ZTZ）和儋州（HDZ），分析了其常规成分、脂肪酸、氨基酸和矿物质。结果显示，HDZ的肌肉粗蛋白含量最高，而FZZ的肝胰腺粗脂肪含量最高（P<0.05）。肌肉组织富含必需氨基酸，ZTZ的浓度最高（190.09毫克/克）。GNS的肝胰腺DHA含量最高（10.87%），n-3/n-6多不饱和脂肪酸比例最高（3.59），而HDZ的EPA含量最高（7.85%）。GNS肝胰腺中的铜浓度最高（546.28毫克/千克），表明需要限制摄入量。与雌性的比较显示出显著的性别相关营养差异。这些发现突出了雄性青蟹营养特征的显著区域差异，强调了它们对人类营养和水产养殖发展的价值。
