  • Description:
    The shark complex (spiny dogfish, Pacific sleeper shark, salmon shark and other/unidentified sharks) in the Gulf of Alaska (GOA) is assessed on a biennial stock assessment schedule that coincides with the availability of new trawl survey biomass estimates. In alternate (even) years we present an executive summary to recommend harvest levels for the next two years. For detailed information regarding the assessment, please refer to the last full stock assessment, which is available online (Tribuzio et al. 2015, http://www.afsc.noaa.gov/REFM/Docs/2015/GOAshark.pdf). A full stock assessment document will be presented in next year’s SAFE report. The complex acceptable biological catch (ABC) and overfishing level (OFL) are based on the sum of the ABC and OFL calculations for the individual species. For an off-cycle year, there is no new survey information for the shark stock complex; therefore, the 2015 estimates are used in 2016 assessment.
