Description

Abstract: A joint, Canada-United States stock assessment of Pacific ocean perch (Sebastes alutus) off British Columbia, Washington, and Oregon was completed for the period 1956-74. Data analyzed included catch statistics from all participating nations, size and age composition of commercial landings in Canada and the United States, and biomass estimates based on research vessel catches. In the Hecate Strait-queen Charlotte Sound region (B.C.), three stocks were identified, one of which was relatively large and unutilized, one small and moderately utilized, and one now small and overutilized. In the Vancouver-Oregon region all stocks are now small and overutilized.

Purpose: A joint analysis of the condition of Pacific ocean perch stocks off the U.S. and Canadian coasts was carried out in 1971-72 at the request of the Technical Sub-Committee of the International Groundfish Committee. The results of this analysis were summarized in Westrheim et al. (1972), and annual updates of key tables in that report have served to keep assessment of stock conditions current. A significant amount of information useful for stock assessment has become available since 1972, and extensive re-appraisal of stock conditions is now appropriate. Consequently, the Technical Sub-Committee requested that a working group of United States and Canadian scientists prepare a detailed report on the status of Pacific ocean perch stocks in the Oregon-British Columbia region as of 1974. This report summarizes the results obtained by that working group.
