Description:

Fish previously referred to as rougheye rockfish are now recognized as consisting of two species, the rougheye rockfish (Sebastes aleutianus) and blackspotted rockfish (Sebastes melanostictus) (Orr and Hawkins 2008. The current information on these two species is not sufficient to support species-specific assessments, so they are combined as a complex in one assessment. The assessments from 2008-2015 were based on an age-structured model which has been applied to the Aleutian Islands (AI) portion of the population whereas the eastern Bering Sea (EBS) portion of the population are assessed with Tier 5 methods applied to survey biomass estimates. In this assessment, we recommend an age- structured model applied to the BSAI area, and use of the EBS slope survey biomass estimates and age composition.
