Maine fishery officials are holding public hearings on proposed rules for the upcoming scallop fishing season. The Department of Marine Resources has proposed rules that create three scallop zones along the coast, with some localized areas in eastern Maine being open and closed to fishing year-to-year on a rotational basis. For the coming season, regulators are proposing a 64-day season beginning Dec. 2 and ending in March for the entire coast except Cobscook Bay in far eastern Maine. Two options are being put forth for Cobscook Bay, with different season dates and catch limits. Monday’s hearing is being held at the University of Maine-Machias. Other hearings are scheduled Tuesday in Ellsworth and Thursday in Wiscasset. Scallops provide a supplemental income in the winter for fishermen.
