Fish - Herring (Clupea harengus)

Fish - Herring (Clupea harengus)

Based on the most recent estimates of SSB and fishing mortality, ICES classifies the stock as having full reproductive capacity and being harvested sustainably. The 1998, 1999, 2002 and 2004 year classes dominate the current spawning stock which is estimated to 12.6 million t in 2009. Preliminary indications show that the year classes 2005-2008 are below average.  Therefore the abundance of herring in the Barents Sea is believed to be at a relatively low level in 2009.

Fish - Polar cod (Boreogadus saida)

Fish - Polar cod (Boreogadus saida)

The polar cod stock is presently at a high level (Figure 4.3.28). Norway took some catches of polar cod in the 1970s and Russia has fished on this stock more or less on a regular basis since 1970. The stock size has been measured acoustically since 1986 and the stock has fluctuated between 0.1-1.9 million t. In 2008, the stock size was measured to about 1.2 million t., which is equal to the estima...

Fish - Blue whiting (Micromestisius poutassou)

Based on the most recent estimates of fishing mortality and SSB, ICES classifies the stock as having full reproductive capacity, but being harvested unsustainably. SSB increased to a historical high in 2003 but has decreased since, and is expected to be just above Bpa in 2009. The estimated fishing mortality is well above Fpa. Recruitment in the last decade appears to be at a much higher level tha...

Fish - Saithe (Pollachius virens)

Based on the most recent estimates of SSB, ICES classifies the stock as having full reproductive capacity. Based on the most recent estimates of fishing mortality, ICES classifies the stock to be harvested sustainable. Fishing mortality is stable and has since 1996 been below Fpa. The SSB (Figure 4.3.30) has since 1994 been well above Bpa. After a long period of low stock size, the stock recovered...

Marine mammals

Marine mammals

High Arctic endemics occupying the Barents Sea Region include the polar bear, walrus, ringed seal, bearded seal, harp seal and hooded seal, white whale, narwhal and bowhead whale. All of these animals are associated with sea ice through much or all of their annual cycle and hence are currently a conservation concern because of the declines in arctic ice coverage over recent decades and predictions...
