In this report the results of the cod monitoring program are presented. This research was commissioned by the Dutch Ministry of Economic Affairs. Cod catches of the vessels in the gear groups BT2 (beam trawl) and TR (otter trawls and seines) need to be monitored yearly, due to the Dutch implementation of the European cod recovery plan. The European cod recovery plan restricts fishing efforts of European fleets that catch cod. Fishing effort, based on historical track records, is allocated to different gear groups. Fishing effort can be transferred between gear groups but then conversion factors apply. In the Netherlands fishing effort is transferred yearly from the BT2 gear group to the TR group, based on a national conversion factor of 1:3 (BT:TR) kWdays instead of the European conversion factor of 1:16, because the cod catches in the Dutch TR fleet are not as high as the European conversion factor implies. In order to substantiate for the national conversion factor, the Dutch government is obliged to report cod catches per unit of effort (CpUE) of the vessels in these gear groups to the European Commission.
