WP6: Building a decision support model for integrated governance Rationale WP6 will combine the work done in work packages 2, 3, 4 and 5 by creating a holistic Bayesian decision support model for the integrated governance of Baltic salmon and herring. The model will be used to analyze the impact of salmon and herring and their management on each other, on the dioxin concentration and on human health under different scenarios, and the impact of the different management options on these. The management options that will be incorporated in the model relate to a) reducing dioxin in salmon and herring, b) sustainable use of salmon and herring, c) reducing eutrophication, d) guiding the consumption of salmon and herring, could benefit the society in terms of reduced dioxin in fish while at the same time ensuring sustainable catches for both species. Importantly, the model will be used to analyse fishers’ commitment to the decision options that relate to fishing. Moreover, as the core question of the whole project, the decision support tool will be used to analyse the success of different types of governance structures in implementing ecosystem based management, and the consequences of them from the perspective of decisions. It will also be analysed which is the most beneficial governance level to involve stakeholders, if the aim is to enhance fishers’ commitment to management decisions. The tool enables an integrated risk analysis for examining biological, cultural, and governance-related uncertainties in relation to biological, social and governance-related utilities. Objectives Holistic decision analysis of Baltic salmon and herring fisheries and management measures aiming at social, biological, and health-related utilities.
