Includes bibliographical references. "Need for accurate assessment of the state of stocks of Pacific ocean perch (Sebastes alutus) and estimation of optimum sustainable yield, has necessitated a re-examination of foreign fishery statistics. Published data do not provide reliable information on the catch of S. alutus as distinct from other rockfishes. The report describes the techniques used to derive this information and provides estimates of the annual removals from 1965 to 1976 for Queen Charlotte Sound, the principal fishing area for S. alutus adjacent to the British Columbia coast"--Abstract, page iv.
