Includes bibliographical references (p. 9). "In Barkley Sound, Pacific Fishery Management Area 23, eight Geoduck density dive surveys were conducted between 2000 and 2014 to estimate Geoduck density on a portion of the beds open to commercial harvest. Three large long-term closures to commercial Geoduck harvest are located within Area 23: the Broken Group Islands and West Coast Trail portions of the Pacific Rim National Park Reserve, and the Bamfield Marine Sciences Centre research closure. Between 2012 and 2014, substrate mapping surveys were conducted to identify potential Geoduck habitat within the three long-term closures. Subsequently, four density dive surveys were conducted on potential identified habitat within the closures between 2012 and 2014"--Abstract, p. v.
