To develop the ecological components 2. Describe trophic relationships in selected marine and freshwater ecosystems in West Africa, Asia and the Caribbean 3. Explore ecosystem-level impacts on fishing effort and environmental stresses.

3. WP4: Development of the Ecological component of the ECOST model Summary of Work Description. Summary of Work Description. Work is description is divided into four sections: Work is description is divided into four sections: 1. WP4.1. Methodology using the Ecopath with Ecosim (EwE) approach 2. WP4.2. Time series fitting in Ecosim: evaluating fisheries and environmental effects 3. WP4.3. Addressing uncertainty 4. WP4.4. Applications.
