Abstract
The paper deals with the results of the data analysis of red king crabs trap catches and bottom temperature in summer 2008-2018 in the coastal part of the southern Barents Sea and adjacent waters of the White Sea. Such factors as a 5-day period of survey, depth of catch, seabed type, bottom temperature and interannual changes as mixed factor were assessed. Inverse relation between caches of berried females with bottom temperature and depth of catch was detected. Crabs of other functional categories have not got strong relations with these factors. The highest influences type for crab catches was detected. It was complex of factors which drive interannual variability in quantity of crabs aggregation. Catches of berried females of red king crab has depended on bottom temperature and depths. It is recommended to carry out the trap survey on the southern part of the Barents Sea within 30 days. Deviations in survey on research stations should not be more than 10 days.
