By-catch of Skates in Trawl and Long-Line Fisheries in the Barents
The occurrence of skates (Rajidae) in the by-catch of trawl and long-line fisheries in the Barents Sea are described. The dominant species captured were thorny skate or starry ray (Amblyraja radi-ate), arctic skate (A. hyperborea) and round skate (Rajella fyllae), whereas blue or big skate (Dipturus...
