"Not to be cited without permission of the authors." Includes bibliographical references (page 9). "Differences in the catch-at-age matrices used by Canada and the United States are explored, and possible reasons for observed discrepancies suggested. While it appears that age determination biases are not the main cause of the discrepancies in the catch at age matrices, the evidence is not conclusive. It is suggested that differences in catch at age due to lack of agreement in ageing are less significant than those due to differing length compositions of catches for the two countries. We therefore recommend use of the sum of the catch at age derived from each country's sampling data"--Abstract, page 2. Includes abstract and series statement in French.
