Reconciling single-species TACs in the North Sea demersal fisheries using the Fcube mixed-fisheries advice framework ArchiMer
Ulrich, Clara; Reeves, Stuart A.; Vermard, Youen; Holmes, Steven J.; Vanhee, Willy.
Single-species management is a cause of discarding in mixed fisheries, because individual management objectives may not be consistent with each other and the species are caught simultaneously in relatively unselective fishing operations. As such, the total allowable catch (TAC) of one species may be exhausted before the TAC of another, leading to catches of valuable fish that cannot be landed legally. This important issue is, however, usually not quantified and not accounted for in traditional management advice. A simple approach using traditional catch and effort information was developed, estimating catch potentials for distinct fleets (groups of vessels) and metiers (type of activity), and hence quantifying the risks of over-and underquota utilization...
