An experimental trawl net fitted with a 120 mm square-mesh escape panel was tested against the standard trawl net of the Irish Sea Nephrops fishery. The experimental net allowed 54% of juvenile haddock and 65% of juvenile whiting to escape, and there was no loss in catches of the targeted Nephrops.

Gillnets from the North Sea wreck net fishery equipped with pingers, had a 100% reduction in the bycatch of harbour porpoises, compared to nets with no pingers attached.

Crab traps were fitted with a Turtle Excluder device to reduce the incidental capture of diamondback terrapins. No diamondback terrapins were caught during this study but the total catch rate of targeted blue crabs, compared to the standard traps, increased by 25.7% (14.5% sublegal size, 32.9% legal size). The difference in total catch rates and catch rates of legal sized blue crabs between the two traps were significantly different.
