Gulf of Maine/Bay of Fundy Stock STOCK DEFINITION AND GEOGRAPHIC RANGE This stock is found in U.S. and Canadian Atlantic waters. During the summer (July to September), harbor
porpoises are concentrated in the northern Gulf of Maine and southern Bay of Fundy region, generally in waters less than 150 m deep (Gaskin 1977; Kraus et al. 1983; Palka 1994a). During fall (October-December) and spring (April-June), harbor porpoises are widely dispersed from North Carolina to Main...
