Species identification in Haliotis genus from the northeastern Pacific Ocean using genome-wide RAD-SNPs

摘要: Abalone is a marine gastropod mollusk that belongs to the genus Haliotis high-priced and with commercial importance worldwide. Because of its high demand, its products are susceptible to retail fraud by substituting lower-value products or protected species instead of higher-value ones. Therefore, species identification is a crucial traceability element, and restriction-site-associated DNA sequencing (RAD-seq) is a genomic tool that permits achieving this goal in non-model species with few developments in genetic data. This study analyzed five ecological and socio-economically important abalone species that inhabit the west coast and islands of the Baja California Peninsula (BCP), Mexico: green H. fulgens, pink H. corrugata, red H. rufescens, black H. cracherodii and threaded/pinto H. kamtschatkana abalones. The number of putative bi-allelic single nucleotide polymorphisms (SNPs) found across the five …
