The Department of Fisheries of the Dutch ministry of LNV1 has asked for research on the question: “What are the possible effects of alternative fisheries management strategies (for example Multi-Species TACs) on the behaviour of the Dutch and international fleets and the manageability of fishing pressure?” A simulation framework was used to investigate the performance with respect to the biological and economic sustainability of three alternative management scenarios in a two-species system. The system mimics the exploitation of sole and plaice in the North Sea. At present a large proportion of plaice is caught as by-catch of the main beam trawl fleet targeting sole, and yet current management of the two stocks assumes no interaction in their exploitation. Within the simulation, the annual stock assessment (using XSA) and projections are still carried out in a single species manner, but the management choices and decisions are executed interactively.
