Review, validate and update data and model for western Baltic spring-spawner herring (113570)

The goal of the project is to establish and follow a roadmap to improve data input, model configuration, and management advice for western Baltic spring-spawner (WBSS) herring by a national team of partners and international collaborators in an ICES scheduled benchmark process within the project period. This includes improving and possibly extending the catch time series, the survey indices, and the biological data. The project will notably use innovative state-of-the-art modelling for splitting data into stocks in the areas where they mix.

The updated data will be used in the stock assessment model with the goal of getting the most accurate perception of the stock. New fishing and biological reference points will be estimated using an innovative within the model procedure that will ensure the quality of the advice projections and the sustainability of the stock in the future.

Funding
The project is co-funded by the European Union through the European Maritime, Fisheries and Aquaculture Programme (EMFAF).
