A “snowcrab-bag” attached to the fishing line of Campelen 1800 research trawl : Does it affect the catch rates and species composition in the cod end?

For monitoring abundance and distribution of snow crab in the Barents Sea, data from the bottom trawl surveys in winter (February) and in autumn (August-September) are used. The data collected in the autumn survey is especially important, since provide the basis for quota advice on the fishery for s...
