520 |aFor assessment purposes, slope rockfish include seven species: Pacific ocean perch, yellowmouth rockfish, redstripe rockfish, rougheye rockfish, shortspine/longspine thornyheads, and shortraker rockfish. These are managed within six major areas (3C, 3D, 5AB, 5CD, 5ES, 5EN), giving a total of 42 species-area combinations. Historically, these 42 assessment units have been managed with reference to a benchmark stock of Pacific ocean perch in Area 5AB. A catch-at-age analysis of this stock played a central role in the assessment. This assessment differs from past reports in three principle respects. First, a new trawl observer database was used to examine abundance ratios among species and areas. Second, information gathered from experienced members of the industry was used, and some of their concerns was recorded. Third, a new catch-at-age analysis of the benchmark stock was not included. No new survey data are available to alter substantially the 1997 analysis.
