Report of the Working Group on Multispecies Assessment Methods (WGSAM)

This is the sixth report of the pan-regional Working Group on Multispecies Assessment Methods (WGSAM). The group met at the Ca’ Foscari University of Venice in Venice, Italy, and reviewed ongoing multispecies and ecosystem modelling activities in each ICES ecoregion. The participants provided an updated inventory, to supplement the information col-lated in 2007-2011 (ToR ‘a’ and ‘b’). New information was presented for Barents Sea, North Sea, Kattegat/Skagerrak, Venice lagoon, Adriatic Sea, Baltic Sea and Northeast US. The group reviewed a new key run for the Baltic Sea SMS. A summary dataset of natural mortalities, stock numbers and biomasses of the modelled species was compiled and is available for download with the report.
