The spawning stock biomass has been above Bpa since 1990, has been increasing in recent years and is at present at historic highest value. Fishing mortality has been around Fpa since the mid 1990s. Recruitment at age 3 has been at or above average since 2000. The year classes 2004-2006 are estimated to be very strong. Surveys indicate that the year classes 2007 - 2008 are below average and 2009 year class is around average.
Harvest control rule
A management plan has been agreed by the Joint Norwegian Russian Fishery Commission and has been in force since 2004 (see annex 3.4.3). It was modified in 2007 from a three-year rule to a one-year rule on the basis of the HCR evaluation conducted by ICES. ICES has evaluated the modified management plan and concludes that it is in accordance with the precautionary principle.
Following the agreed client management plan implies a TAC of 303 kt in 2011, which corresponds to a TAC increase of 25%. This is expected to keep SSB above Bpa in 2012.
Under-reporting of landings has been an important issue for this stock in recent years, fluctuating between 4 % to 34 % of the international reported landings. Non-reported landings (IUU) for the period 2002-2008 were estimated ranging from 6 kt to 40 kt, but the IUU estimate is 0 for 2009.
Unreported landings will reduce the effect of management measures and will undermine the intended objectives of the harvest control rule. It is therefore important that management agencies ensure that all catches are counted against the TAC.
Blim = 50 000 tons
Bpa = 80 000 tons
Flim = 0,49
Fpa = 0,35
Expected fishing mortality in 2010: F = 0,31
Expected spawning stock in 2011: 444 000 tons
