As part of the cod recovery it is possible to transfer the surplus of sea days from beam trawl gear to TR1 and TR2 vehicles. For this a correction is applied based on the CPUE for cod. CPUE, the Catch per Unit Effort, is the number of fish caught in a given period of time, on a given area.
At present, the difference in CPUE between beam and TR harness is large, so a negative correction factor is applied. To be able to apply effective cod management, the Ministry of EL & I needs the CPUE for cod for TR1 and TR2 vehicles.
The aim of this project is to set up a research program to monitor catch and destinations of cod (oversized and undersized - landings and discards) for Dutch TR1 and TR2 vehicles for one year.
