From 1961-1969, 1.5 million zoea larvae, 10,000 1-3 year old juveniles (50% females and 50% males) and 2,609 5-15 year old adult (1,655=females, 954=males) P. camtschaticus from West Kamchatka, was intentionally released by Russian scientists in the Kolafjord in the east Barents Sea (Russia) to create a new and valuable fishing resource in the region (Orlov and Karpevich, 1965; Orlov and Ivanov, 1978). Since then, the member of this crab has successfully formed a resident self-reproducing population that is currently widely distributed in coastal waters off Russia and Norway.
