Code deprecated on 20Dec2019: created in error. Description was: The dredges used to target queen scallops are wider and higher than a traditional scallop dredge. They do not have tooth bar across the front, instead they have either a metal grid, or tickler chains to get the scallops to lift up off the seabed and swim into the dredge. The scallops then fall back into a bag made of metal rings. Some fishermen are replacing the tickler chain and metal grid with a strip of rubber matting across the front of the dredge (source seafish.org).
