Studies were initiated at the Institute of Marine Research, Bergen, in 1984 with the aim of improving the reliability of bottom trawl and acoustic survey results for cod and haddock in the Barents Sea. Spread of the wings and doors and height of the trawl were measured during fishing operations, and...
