摘要: 探索稳定同位素对三疣梭子蟹产地溯源的可行性,可为保护地理标志产品、追溯原产地来源提供理论依据。本研究以黄海、渤海和东海3个主产区海域的三疣梭子蟹为对象,分析了其碳、氮稳定同位素值差异性和不同组织中稳定同位素比值的相关性。结果表明: 不同产地的碳、氮稳定同位素比值有显著性差异,不同组织之间有明显的同位素分馏效应。利用建立的判别分析模型,通过三疣梭子蟹不同组织稳定同位素比值进行产地判别分析,采用肌肉和腮中碳、氮稳定同位素的产地判别正确率(>95%)明显高于肝胰性腺,说明肌肉和腮稳定同位素比值可以对不同海域的三疣梭子蟹进行有效区分。本研究填补了目前三疣梭子蟹稳定同位素溯源技术的研究空白。

Abstract: A method for geographical discrimination of Portunus trituberculatus was explored to provide technical support for the protection of geographical indication products and for tracing the origin of seafood. P. trituberculatus were collected from three major production areas, including the Yellow Sea, the Bohai Sea, and the East China Sea. The variations of carbon and nitrogen stable isotope values of origins and the correlation of stable isotope ratios in different tissues were analyzed. The results showed that there were significant differences in carbon and nitrogen stable isotope ratio among different origins. Significant isotope fractionation effects were observed among different tissues. The discriminant model was developed and the origin discriminant analysis was performed by the stable isotope ratios of different tissues in P. trituberculatus. The correct rate of origin diffe-rentiationf using carbon and nitrogen stable isotopes in muscle and gills (>95%) was significantly higher than that of hepatopancreas and gonad, indicating that stable isotope ratios of muscle and gills could effectively differentiate P. trituberculatus in different sea areas. This study filled the gap of stable isotope tracing technology for P. trituberculatus.

Key words: Portunus trituberculatus, stable isotope, origin tracing, tissue difference
