Abstract = {{A biologically sensible age-length structured multispecies Gadget model
   (incorporating minke whales, cod, herring, and capelin) for the Barents
   Sea-acting as the operating model-has been linked to Fisheries Library
   in R-acting as the management procedure-to perform management strategy
   evaluations. Assessments may be run using either XSA, survey-based
   methods, or by taking modelled stock numbers directly. Total allowable
   catches are based on the assessment and harvest control rules (HCRs).
   The tool can be used for assessing a wide variety of sources of
   uncertainties within the assessment process. Model structure and
   linkages are described and a fit to the historical data is presented. A
   base case of future dynamic (non-steady state) stock trends, based on
   the existing HCRs, is compared with alternative management and
   environmental scenarios. The relative differences for each scenario in
   terms of stock size and catches highlight a number of uncertainties
   within the biological and fisheries system. The results indicate that
   the current management rules are robust to the range of scenarios
   examined so far.}},
