It is a commercially important resource for local fisheries and is currently being used as cleaner fish to control sea lice in salmon farms in northern Europe. We analysed the phylogeographic patterns of this species using mitochondrial (control region) and nuclear (I intron of the S7 gene) markers in populations throughout its distributional range. The results revealed a marked genetic structure of L. bergylta along the sampled area, with a major separation found between the Archipelago of the Azores and all remaining locations and also a clear separation between the north-eastern Atlantic and Scandinavian locations. Similarly to other temperate species the genetic diversity decreased from north-eastern Atlantic to Scandinavian populations. Haplotype networks confirm the distinctiveness of the population from the Azores and show that Scandinavian populations also present some distinct haplotypes. The phylogeographic pattern and diversity indices found for the ballan wrasse are discussed and compared with others found for different labrid species. The recognition of different populations of L. bergylta may be an in important result for fisheries management and also for future regulation of capture and translocation of specimens to be used as cleaners in aquaculture facilities.
