ICES classify the stock as having full reproductive capacity and to be harvested sustainably. Fishing mortality is below Fpa. The spawning stock biomass is above Bpa.
Harvest control rule
ICES evaluated the Harvest Control Rule (HCR) in spring 2007 and concluded that it is consistent with the precautionary approach .The Norwegian Ministry of Fisheries and Coastal Affairs implemented the HCR in autumn 2007. In the management plan evaluations in 2007 the highest long-term yield was obtained for an exploitation level of 0.32, i.e. a little below the target F used in the HCR (Fpa), and ICES recommends using a lower value in the HCR.
ICES advise that landings should be less than 173 000 t. The basis for the advice is the Norwegian Management Plan (HCR). The catches should take account of Sebastes marinus by-catch.
IMR recommends using a lower fishing mortality than Fpa in the HCR. The year-classes since the 2002-year class are confirmed to be poor or at average strength, and the assessment estimates a relatively steep downward trend in the stock biomass since 2005. The spawning stock biomass will further decline the next years if harvesting according to the HCR.
The limit spawning stock biomass (Blim) = 136 000 tonnes
Precautionary approach spawning stock biomass (Bpa) = 220 000 tonnes
The limit fishing mortality (Flim) = 0,58
Precautionary approach fishing mortality (Fpa) = 0,35
Expected fishing mortality in 2010: F = 0,32
Expected spawning stock biomass in 2011: 357 000 tonnes
