Fish - Cod (Gadus morhua)

Fish - Cod (Gadus morhua)

Based on the most recent estimates of spawning stock biomass (SSB, Figure 4.3.19), ICES classifies the stock as having full reproductive capacity and being harvested sustainably. Based on the most recent estimates of fishing mortality, the stock is at present exploited with a fishing mortality below that intended under the agreed management plan. The SSB has been above Bpa since 2002. Surveys indicate that the 2004-2005 year classes are above average while the 2006-2008 year classes are below average.

Fish - Haddock (Melanogrammus aeglefinus)

Fish - Haddock (Melanogrammus aeglefinus)

Based on the most recent estimates of SSB (Figure 4.3.21), ICES classifies the stock as having full reproductive capacity and being harvested sustainably. The fishing mortality has fluctuated around Fpa during the last 10 years. The assessment indicates that the spawning stock is at a high level. Very strong year classes of 2004-2006 are recruiting to the fishable stock in 2008-2010, and thus the ...

Fish - Redfish (Sebastes mentella and Sebastes marinus)

Deep-Sea Redfish (Sebastes mentella)

Recruitment failure has been observed in surveys (Figure 4.3.22) for more than a decade. However, signs of improved recruitment are now seen in the Barents Sea. In this regard, it is of vital importance that the juvenile age groups be given the strongest protection from being caught as bycatch in any fishery, e.g., the shrimp fisheries in the Barents Sea and Sva...

Fish - Greenland halibut (Reinhardtius hippoglossoides)

Fish - Greenland halibut (Reinhardtius hippoglossoides)

In the absence of defined reference points and an accepted assessment the status of the stock cannot be fully evaluated. The stock has been at a low level for several years and it is a long-lived species, which can only sustain low exploitation. Indications from fishery independent surveys are that the stock has increased in recent years (Figure 4.3.25). During the last 15 years, average catches h...

Fish - Capelin (Mallotus villosus)

Fish - Capelin (Mallotus villosus)

The stock size is increasing. The spawning stock (Figure 4.3.26) of capelin in 2009 is predicted from the acoustic survey in September 2008 and a model, which estimates maturity, growth and mortality (including predation by cod). The model takes account of uncertainties both in the survey estimate and in other input data. For catch levels in spring 2009, below 390,000 t, the probability of having ...
