![]() ![]() Still, we argue in favor of additional studies using more powerful markers (e.g., SNPs) capable of revealing genetic structure at a finer spatial-scale. Therefore, this species can be considered genetically homogeneous and a single fished stock. Using sequences of the 16S-mt-DNA marker, we found no indication of population genetic structure in the endemic L. Misidentification in the shrimp aquarium trade is accidental and involuntary, and is explained by remarkable similarity among congeneric species. boggessi being the most traded species worldwide. The intensity of the market for peppermint shrimps in the USA has led to L. boggessi as the only species in the trade. ![]() Importantly, only when color pattern or genetic markers in conjunction with morphological traits were employed, was it was possible to unequivocally identify L. We demonstrated, contrary to popular belief (information from dealers), that the most heavily traded species in the market was Lysmata boggessi, an endemic species to the eastern Gulf of Mexico, and not Lysmata wurdemanni. Shrimps were bought from aquarium shops in FL, GA, SC, and NC. We surveyed the peppermint shrimp ornamental marketplace in the southeastern USA, the most intense market for peppermint shrimps worldwide, to characterize the composition of species in the trade, reveal the extent of misidentification, and describe the population genetics of the true target species. ![]() Minimizing misidentification is critical in the face of overexploitation of species in the trade. The ornamental trade is a worldwide industry worth >15 billion USD with a problem of rampant product misidentification. ![]()
