 Weir fishing also benefits from the tides.At high tide the weir is submerged, fish swim in to the weir and, at low tide, the fishermen row in and scoop up the fish that are trapped at low tide.Major communities situated on St. Marys Bay include Sandy Cove, Weymouth, Belliveaus Cove, Comeauville, Saulnierville, and Meteghan.
