Size at maturity of female red king crab, Paralithodes camtschaticus, from the costal zone of Kola Peninsula (southern Barents Sea)
The red king crab, Paralithodes camtschaticus (Tilesius, 1815), is a large commercial species introduced in the Barents Sea. The aim of this study was to estimate the size at maturity (SM50) in female red king crab sampled at three costal sites of the Russian parts in the Barents Sea. Females were d...
