The objective of the EFIMAS project is to develop an operational management evaluation framework that allows evaluation of the trade-off between different management objectives when choosing between different management options. The evaluation framework will be developed to inform an exploratory, adaptive decision- making process. Evaluation tools will be developed to appraise the biological, social and economic effects of fisheries management measures in the EU, and these will be applied to important fisheries, including Baltic cod and Baltic salmon. The overall approach will use stochastic simulation techniques. The tools will take account of the dynamics in the fisheries systems, as well as of uncertainties and will include risk assessments.
