Management of mixed cod stocks in the transition zone between the North Sea and the Baltic Sea: How can this be achieved most efficiently? (39702/102587)

In this project, we aim to improve the stock assessment and advice giving for cod stocks in the inner Danish waters, with special focus on Kattegat and the western Baltic Sea, where mixing of stocks is known to be extensive. The goal is to develop the most ideal approach to management that implements these mixing dynamics, including the biological developments of each stock, while concurrently considering the feasibility of the approach from a data collection perspective.

The objectives of the project are:
1. To collate biological knowledge from previous projects and historical tagging data, mapping migrations of cod
2. Identify stock structure of cod from the Skagerrak to the western Baltic Sea using the development of genetic stock identification
3. Map migration dynamics between management areas
4. Develop a generic management tool that can identify optimal assessment and management strategies under consideration of stock mixing and migrations
