在日本和台湾的两个地区，有商业性捕捞的虾Lucensosergia lucens（日语为'Sakuraebi'）。为了了解虾的捕捞区域的地理来源，我们研究了在骏河湾，日本（日本虾）和台湾（台湾虾）使用电感耦合等离子体质谱仪捕获的虾之间的身体含量的60种元素的差异。砷（As）的含量被发现是明显不同的日本和台湾虾，是较低的日本虾，允许几乎完全分离的两个起源。日本虾的锶/砷（Sr/As）比高于台湾虾，无论是测试生或干标本。Sr/As比值的阈值限值为25，区分日本和台湾虾。这两个值的组合应用（即，As含量和Sr/As比值）强烈区分该物种的成员从两个地理起源。
The shrimpLucensosergia lucens(‘Sakuraebi’ in Japanese) is commercially fished in two areas in Japan and Taiwan. To understand the geographical origin of the fishing area of the shrimp, we examined differences in the body content of 60 elements between shrimp caught in Suruga Bay, Japan (Japan-shrimp) and those caught off Taiwan (Taiwan-shrimp) using inductively coupled plasma mass spectrometry. Arsenic (As) content was found to be distinctly different between Japan- and Taiwan-shrimp, being lower in Japan-shrimp, allowing an almost complete separation of the two origins. The strontium/arsenic (Sr/As) ratio of Japan-shrimp was higher than that of Taiwan-shrimp, regardless of testing on raw or dry specimens. The Sr/As ratio had a threshold limit value of 25, which distinguished Japan- and Taiwan-shrimp. The combined application of these two values (i.e., As content and Sr/As ratio) strongly differentiated members of this species from the two geographical origins.
