Working Groups and Committees

Working Group - CommitteeTasks
Working Group on Beam Trawl Survey (WGBEAM)Coordination of different beam trawl surveys in the North Sea and adjacent waters as well as the compilation and analysis of the data collected for the estimation of relative indices for stock assessments
Working Group on the Assessment of Demersal Stocks in the North Sea and Skagerrak (WGNSSK)The WGNSSK working group provides advice on single species catch quotas (TAC). Using historical information on catches and survey indices, quantitative models are used to assess the current population size and forecast future conditions
Working Group on Crangon Fisheries and Life History (WGCRAN)Compilation of landing data from the brown shrimp fishery as well as analysis of biological data and survey data of Crangon crangon
Benchmark Workshop for North Sea Stocks (WKNSEA)Evaluation and further development of existing assessment models for demersal stocks in the North Sea and adjacent waters. This working group operates in the form of workshops complementary to the WGNSSK
