A new toothless dredge design called the "Newhaven" was tested in the Isle of Man queen scallop fishery, to determine it's effect on both catch and bycatch. This new dredge design caught significantly more queen scallops compared to the traditional tooth dredge. However, there was no significant difference between the abundance of bycatch between the two dredge designs. Bycatch species composition between the two dredge types was relatively similar but the "Newhaven" dredge did catch a significant number of dogfish.
