Map of sampling sites around the Korean Peninsula used for this study (labeled points), augmented with results from previous genetic analyses in the surrounding region (Canino et al., 2010; Smirnova et al., 2019; Suda et al., 2017). Point coloration represents the putative populations of each site according to the genetic structure described by RAD loci (this study) and microsatellite DNA (msDNA; previous studies). The approximate path of the Tsushima Warm Current (TWC), with primary branching in the Strait, is traced by the dashed orange arrows
