Annual Growth Rings and Rate of Growth of the Giant Scallop, Placopecten magellanicus (Gmelin) in the Digby Area of the Bay of Fundy

The growth rings on the valves of scallops collected from the Digby area of the Bay of Fundy are formed only once a year during the winter. Observations of special collections of small scallops have also shown the position of the first growth ring. This information has been used to construct a general growth curve from measurements of annuli on scallops from the Digby area.
