Abstract

Background: This is the first record of the alien shrimp Mierspenaeopsis sculptilis in Brazil. The invasion was detected within Marine Extractive Reserves based on eight specimens accidentally caught by local fishermen using trawlnets focused on fisheries of native species. These specimens were transported to the Laboratory of Applied Genetics and morphologically identified as Mierspenaeopsis sculptilis (rainbow shrimp). The taxonomic status of analyzed samples was confirmed by DNA barcoding using a 627-bp fragment of the Cytochrome C Oxidase Subunit I (COI) gene.

Results: A single haplotype was recovered from the eight specimens, being identical to a haplotype reported in India, where this species naturally occurs, and in Mozambique, where the rainbow shrimp is considered an invasive species. The present analyses indicated a putative invasive route (i.e., India-Mozambique-Brazil) mediated by shipping trade.

Conclusions: This study presents the first record of Mierspenaeopsis sculptilis in Brazil, in areas of extractive reserves on the Amazon coast. Notably exotic species can cause imbalance in the ecosystem, harming native species. In view of this, the registration of new invasions is essential as they contribute to the implementation of control plans.

彩虹虾，外来物种Mierspenaeopsis sculptilis (Heller, 1862)，在巴西沿海亚马逊首次记录，并通过DNA条形码验证。

背景:这是巴西首次记录到外来对虾Mierspenaeopsis sculptilis。该物种的入侵是在海洋开采保护区内发现的，基于当地渔民使用拖网捕捞本地物种时意外捕获的8个标本。这些标本被运送到应用遗传学实验室，经形态学鉴定为彩虹虾。利用细胞色素C氧化酶亚单位I (COI)基因627-bp片段进行DNA条形码鉴定。结果:从8个标本中恢复了一个单倍型，与印度报告的单倍型相同，该物种在印度自然发生，在莫桑比克被认为是入侵物种。目前的分析表明了一条假定的由航运贸易介导的入侵路线(即印度-莫桑比克-巴西)。结论:本研究在巴西亚马逊海岸的采伐区首次记录了雕刻型Mierspenaeopsis sculptilis。值得注意的是，外来物种会导致生态系统失衡，危害本地物种。鉴于此，登记新的入侵是必不可少的，因为它们有助于执行控制计划。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
