ObjectivesTo use the twin trawl system to collect selection data (L50, selection factor and range) with a 45mm small mesh cod-end rigged on one net. On the other net the test cod-ends were the new EC cod-end mesh sizes of 90mm diamond mesh, 100mm diamond mesh with 100 meshes round, 100mm diamond mesh with a 90mm square mesh window. Additionally it was planned to test possible UK tie-up derogation mesh sizes of 110mm and 120mm mesh with restricted meshes if time was available. Underwater observations were planned to check the symmetry of the twin trawling rig and to obtain film of fish reactions, with the RCTV system.
