Some biological parameters of the local group of rеd king сrаb in the Dalnezelenetskaya Bay (Barents Sea) are determined in summer 2013. The large-sized mature сrаbs with the carapace width > 100 mm prevailed in scuba diving catches, with equal proportion of females and males. The females with violet eggs dominated among the egg-bearing females. Barren females were not caught. Percentage of the limbs injuries was 62 % that was lower than in the previous year. Total stock of red king crab in the bay was assessed as 4750 individuals. Significant increasing of the large-sized males abundance is noted that corresponds with general growth of their stock in the Barents Sea after the ban on the species fishery within the 12-mile coastal zone in 2011.
