520	|aThis paper represents a major assessment for sablefish. The assessment is based on an integrated catch-age, mark-recapture model that is stratified by area and depth. The unified approach is a significant improvement over the previous assessment that analyzed catch-at-age and tagging data separately. Estimates of available biomass in 1997 range from 43,400 to 51,300 t. A recommended yield range of 2,977 t-5,052 t was developed based on deterministic projections using varying levels of recruitment and target F levels based on the current F (Current), 0.8F current and 1.2F current. Under all scenarios with average or below average levels of recruitment the stock is predicted to decline slowly. A yield level chosen from low-average recruitment options is recommended.
