The SSC received a report regarding ongoing analyses of different ways to spatially apportion the sablefish stock sub-area ABCs across management regions in the GOA and BSAI. Preliminary results indicate limited biological differences amongst apportionment schemes. Final analyses of a range of apportionment schemes and their performance against some biological and economic objectives will be presented in conjunction with the fall sablefish assessment.
In responding to the SSC’s report, the Council indicated that the SSC should continue to assess and make recommendations on the appropriate sub-area or aggregate (e.g., GOA-wide) ABCs for the sablefish stock based upon biological aspects of the stock, while economic concerns about area splits will be addressed by the Council in the TAC-setting process. Modifications to the ABC spatial apportionment will be considered during the annual specifications process and do not require additional analyses beyond what is already planned.
