Effects of ocean variability on recruitment and an evaluation of parameters used in stock assessment models. Can. Spec. Publ. Fish. Agnat. Sci. 108: 379 p. Invited speakers from Canada, The People's Republic of China, Japan, the United States of America, and the Union of Soviet Socialist Republics met in Vancouver, British Columbia, Canada, to discuss the effects of ocean variability on recruitment and to evalu- ate the accuracy of parameters used in stock assessment models. In addition to providing new information on two important topics, the symposium attempted to stimulate commu- nication among fisheries and oceans scientists and to encourage interdisciplinary research. The symposium also provided an example of the potential benefits of a proposed new North Pacific fisheries and oceans science organization. Résumé BEAMISH, R. J., AND G. A. MCFARLANE [ED.]. 1989.

Des conférenciers invités du Canada, de la République de Chine, du Japon, des États-Unis et de l'Union des républiques socialistes soviétiques se sont réunis à Vancouver en Colombie-Britannique (Canada) afin d'étudier les effets de la variabilité des océans sur le recrutement et d'évaluer la précision des paramètres utilisés pour les modèles d'évalua- tion du stock. En plus de fournir de nouvelles données sur deux sujets importants, le colloque visait à stimuler la communication entre les halieutes et les océanologues et à favoriser les recherches interdisciplinaires. Le colloque a aussi fourni un exemple des avantages potentiels relativement à une nouvelle organisation scientifique des pêches et des océans dans le Pacifique nord. v Sponsors International Pacific Halibut Commission University of Alaska University of British Columbia National Marine Fisheries Service Canada Department of Fisheries and Oceans International North Pacific Fisheries Commission (INPFC) International Recruitment Investigations in the Subarctic (IRIS) Steering Committee Canada Dr. R.
