Rebuilding Western Baltic Spring Spawning (WBSS) herring (GENBYGSILD)

This report details results generated in connection with the European Marine Fisheries Fund funded project GENBYGSILD (English title: Rebuilding Western Baltic spring spawning herring). The aims of GENBYGSILD were to: Improve knowledge about biology (spawning timing, areas, distribution of biologically unique sub-stocks, sub-stock specific migrations, and potential drivers) of herring populations spawning in the Western Baltic Sea (Western Baltic Spring Spawning, abbreviated WBSS, herring) in the area spanning from the Skagerrak-Kattegat-Danish Belt Sea to the western parts of the Baltic Sea, perform quality control and critical evaluation of stock assessment models, and re-evaluate biological reference points, and develop management strategies that incorporate rebuilding plans for WBSS herring. DTU Aqua was the main project leader, with contributions from Danish Fishers Producers Organisation and Danish Pelagic Producers Organisation. The project also incorporated collaborations with international institutions Swedish University of Agricultural Sciences in Sweden and Thünen Institut für Ostseefischerei in Germany.
