Dover Sole Welfare: Beam Trawling and the Price of a Luxury Fish

Dover sole commands premium prices in European restaurants, but the beam trawling used to catch them is one of the most destructive and welfare-damaging fishing methods in use.

Key Facts

Dover sole is one of the most commercially valuable flatfish in European waters
Beam trawls drag heavy metal beams and tickler chains across the seabed to flush sole from the substrate
Beam trawling has a very high bycatch rate and destroys benthic habitat with each pass
North Sea beam trawl fuel consumption is among the highest of any European fishing method
Some Dover sole is now caught using pulse trawling — electric stimulation replacing tickler chains — which has lower bycatch but its own welfare concerns

Welfare Considerations

Beam trawling for Dover sole causes welfare harm across multiple dimensions: target fish experience the trauma of trawl capture; bycatch species including rays, small sharks, and invertebrates are crushed or discarded; benthic communities including sponges and tube worms are destroyed. Pulse trawling reduces physical bycatch but electric stimulation causes spinal injuries in some species including cod. The premium price of Dover sole provides economic space for fishing operators to transition to more selective, lower-welfare-impact methods.

What You Can Do

Ask restaurants and fishmongers about the catch method before ordering Dover sole
Support pulse trawl regulations that address electric stimulation welfare concerns
Back marine protected area designations that exclude beam trawling from sensitive benthic habitats
Choose lower-impact flatfish alternatives caught by hook-and-line or pot methods
