Sea scallop population assessments are routinely made in the Digby and Grand Manan areas of the Bay of Fundy, but no comprehensive scallop survey has been made in the upper part of the Bay. In 1984-85, the area around Quaco Ledge and Ile Haute was heavily fished and, partly in response to this commercial activity, a survey was undertaken to determine scallop distribution. The survey consisted of 3 cruises, with the upper Bay surveyed in May 1986 and August 1986, and the northern side of the Bay from Quaco Head to Maces Bay in June 1987. The survey gathered baseline data on populations, associated fauna, and biological parameters.
