Abstract

Annual trawl surveys conducted by Polar Research Institute of Marine Fisheries and Oceanography (PINRO) in the Barents Sea during 1998–2001 have been used to describe the distribution, habitat (temperature, salinity and depth), size distribution and sex ratio of six species of skates (thorny skate, Amblyraja radiata; Arctic skate, Amblyraja hyperborea; round skate, Rajella fyllae; blue skate, Dipturus batis; spinytail skate, Bathyraja spinicauda; and sail ray Dipturus linteus). The relative biomass and abundance of the five species are presented.

Key words: Barents Sea, depth, distribution, habitat, length, salinity, skates, temperatures
