Norwegian and Russian scientists recently concluded this year’s joint ecosystem mission to the Barents Sea. The conclusion is that the cod stock in the Barents Sea has set a new record when it somes to northern distribution.
The Russian research vessel “Vilnjus” found cod as far north as 82 degrees 30 minutes north.
The cod stock in the Barents Sea is considered to be the largest in the world. The quotas for 2013 will probably be over 900.000 tons.
“The northernmost observations were of rather small amount of fish, but we still see a trend that the main stocks of the North Atlantic cod migrate further north and east than earlier”, mission leader Harald Gjøsæter says to the Institute of Marine Research’s web site.
The reasons for the record distribution are according to the scientists higher sea temperatures and sufficient supply of food.

The scientists use both trawl and acoustic instruments to map the fish stocks in the Barents Sea, and the studies show that the distribution of cod stocks and the capelin stocks are overlapping each other.
“The capelin stocks are also solid, so it looks like the cod has enough food”, Gjøsæter says and adds that it looks like the cod stocks will keep on a high level in the coming years.
The ecosystem mission in the Barents Sea is a collaboration between the Norwegian Institute of Marine Research and its Russian counterpart PINRO. The two organizations have been cooperating since 1958.
Russia’s only aircraft carrier, the Northern Fleet’s “Admiral Kuznetsov”, has finished repairs and is ready to leave the port of Murmansk. According to a Russian news agency, the vessel will sail to Syria.
A century and a half ago, Norway was home to roughly three thousand brown bears, the majority of bears in all of Scandinavia. By 1930, the bears were virtually extinct. Decades of aggressive management tactics and bounties had wiped out one of the area’s most iconic species.
Microplastics, the tiny plastic particles that are accumulating in marine waters and big lakes around the world, are now showing up in the Arctic waters south and southwest of Svalbard, Norway, a new study says.
REYKJAVIK: The climatic changes taking place in the Arctic are a call to action for the world. We must answer with more international cooperation and more research, says Tore Hattrem, State Secretary of Norway’s Foreign Ministry.
“Partnership should and shall shape the development of the Arctic, therefore cooperation is the starting point for our Arctic policy,” Vladimir Barbin, Senior Arctic Official and representative to the Arctic Council, said at the Arctic Circle 2015 assembly.
