The preference for coastal habitats makes the harbour porpoise, Phocoena phocoena , vulnerable to fisheries conflicts and hence prone to die due to entangling in fishing nets. An opportunistic sampling of such casualties (134 individuals) in Norwegian waters was used to assess the genetic population structure of the species by SNP-genotyping at 78 loci. The results of genetic clustering obtained for these individuals failed to identify more than one genetic group. Likewise, the individually-based F did not meet an Isolation-by-Distance pattern, thus supporting the conclusion that harbour porpoise in Norway probably belongs to a single genetic group or population.
