Bering Sea and Aleutian Islands (BSAI) Kamchatka flounder is assessed biennially according to the stock assessment prioritization schedule. During odd years, an executive summary is presented with recommendations of harvest levels for the next two years for this species. The most recent full assessment was conducted in 2018, information regarding the stock assessment model and results is available online (Bryan et. al, 2018; https://www.fisheries.noaa.gov/resource/data/2018-assessment-kamchatka-flounder-stock-bering-sea-and-aleutian-islands). A full stock assessment document with updated assessment and projection model results is scheduled for November, 2020.

A forward projecting age structured model is the primary assessment tool for BSAI Kamchatka flounder, which qualifies as a tier 3 stock. The assessment model is not run during an off-cycle year, but the projection model is updated with new catch information. This incorporates the most current catch information without re-estimating model parameters and biological reference points.
