The aim of the project is to develop and test a selective topless trawl to improve selectivity of cod in the demersal mixed species fishery in the northern North Sea. The design idea is based on utilizing behavioral differences between the species where most fish stay low in the trawl but where gadoid species, like cod, raise further aft in the gear and therefore can escape above the cut back headline. An improved species selectivity of cod in the North Sea can allow and economically feasible mixed fishery without further exhausting the cod stocks. In addition to the topless design, a SELTRA sorting box is installed in the aft part of the trawl to compare the selective effect between a relatively large design modifications in the forward part of the trawl with a relative small change in the aft part of the trawl where the behavioral differences between species is less expressed.

The project is coordinated by DTU Aqua.
