The benchmark workshop on capelin (WKCAPELIN) was set up to develop benchmark assessments for the Barents Sea capelin and the Iceland-East Greenland-Jan Mayen capelin stocks. These stocks are distributed in ICES subareas 1, 2, 5, and 14. For Barents Sea capelin, a modification of the existing model approach, which includes multispecies elements (predation by cod), was generally endorsed. Changes to the model approach that were endorsed in the meeting included using a type III rather than type II consumption model; a time averaged (most recent 5 years) CV at age for the autumn survey; 14 cm was to be used as the maturation length cut-off; M and F were now assumed to be constant from January to March; and the year used for the Blim calculation was changed to avoid the early period of the time-series with a low herring stock. Despite these changes, the model results are relatively consistent with the previous assessment. For Iceland-East Greenland-Jan Mayen (IGJM) capelin, a modified version of the existing ...
