In this study, we compared the bycatch reduction capacity of a trawl fitted with standard rigid sorting grid that newly developed, flexible system called Excluder. We conducted fishing trials in Norway pout (Trisopterus esmarkii) small-meshed fishery North Sea. Catch data were analysed by species and length using catch comparison ratio method. The Excluder significantly reduced (in weight) rela...
