title: [Red king crab (Paralithodes camtschaticus) in the Barents Sea: a comparative study of introduced and native populations].
abstract: Red king crab (Paralithodes camtschaticus) was introduced into the Barents Sea in the 1960-1970s. Its present habitation area spans on the coastal zone from Hammerfest (Northern Norway) to the Barents Sea Funnel in the north-east of the Kola Peninsula. We studied the polymorphism of a mitochondrial gene encoding cytochrome oxidase (COI) and five nuclear microsatellite loci in four samples from the Barents Sea and two donor populations from the Western Kamchatka and Primorye. No decrease in the genetic diversity of the introduced populations was detected. Microsatellite assay demonstrated that the sample from Varrangerfjord was distinct from the rest five populations. However, no significant differences between the rest samples were found. Possible reasons underlying this phenomenon are discussed.
