First record of rainbow shrimp, exotic species Mierspenaeopsis sculptilis (Heller, 1862), in the Brazilian coastal amazon, validated by DNA barcode.

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
