To work with the North Sea Regional Advisory Council to develop Long Term Management Plans based on an ecosystem approach.

The work will focus on the North Sea mixed demersal fisheries for cod, haddock and whiting and use ecosystem models to identify and examine the ecological and management trade-offs of alternative plausible management approaches identified by the NSRAC. Management strategy evaluation procedures will help inform management decisions and yield scientific and policy relevant outcomes. An important challenge will be distilling the information (and uncertainties) from complex models into a readily communicable form.

Next Steps

October 2012. Over the next six months, GAP2 scientists will work to better understand how technically, we can develop a tool to evaluate uncertainty in ecosystem models.
GAP2 scientists and RAC members will also work together to develop an interface for our final model, which can be used by both scientists and non-scientists alike.
