Ziel der Reise / Objectives of Cruise:

The investigations of this trip had the objective to reduce the bycatch of flatfish in the bottom otter trawl fishery. The in bottom trawl caught flounder, plaice and dab should escape through laterally arranged grids, which were attached in front of the cod end. Tested were grids with the dimensions 47 cm x 90 cm and the angle of attack 45?. One grid consisted of flexible plastic the other of stainless steel. The catch masses of flounder, plaice and dab were reduced with the Flexi-Grid by 39%, 19% and 54% and with the steel grid by 56%, 38% and 49%.
