A decision support tool will be developed to enable more comprehensive incorporation of the wider effects of fishing within management decisions. This tool and the preceding models will be brought together in a Stakeholder Workshop (W3). A management manual for decision makers and an interactive website will be produced to ensure that the results are readily available, to aid transfer of these techniques to other areas, and to assist the formation of future fisheries regulation. Management decisions can not be based solely on such a partial analysis, and it is recognised that policy makers will not always accept an analysis based on economic values alone, so a more comprehensive multi-criteria decision support tool will be developed, based on the existing proven decision support tool DEFINITE. This model is suitable because it is designed to use the results of experiments in complex decision environments involving many objectives and/or many participants. It is essentially participatory, so the tool will be implemented using a facilitated stakeholder workshop. This will involve the RUG (see above), scientific partners, other scientists from national research institutions, representatives of fishers and where relevant recreational users, representatives of the relevant DGs and national Ministries, other managers, and other interested stakeholders. The workshop will aid in establishing model parameters, valuations and exploring management issues within this workpackage. A management manual will be produced to set the results of the ecological modelling and economic analysis in the context of the current fisheries policy and regulatory framework, as management issues will extend beyond changes in fishing effort and yield. The manual will be developed to ensure that the results are readily available, and transferable to other areas, to assist the formation of future fisheries regulation, and to provide guidelines for applying the methodology to other marine areas. An interactive website will allow stakeholders to explore the models, the decision tool and the consequences of varying assumptions and parameters.
