Water Biological Resources Development in the Arctic Region and International Cooperation, Tromsø, September 16th, 2010

Norwegian – Russian Fishery Scientist Meeting, PINRO, Murmansk, March 2009

Fisheries research cooperation with Russia

• Contact between Norwegian and Russian scientists since 1887 (Knipovitch in Oslo with R/V «Andrey Pervozvanny» and meet with Nansen og Hjort in 1898)

• More ore less formalized cooperation last 50 years• Joint surveys for abundance estimaton of fish and shellfish• Coordination of research on biological resources • Joint programs and projects • Joint symposias (biannual)• Exchange of scientists end technical experts • Exchange between bibliothecs • Implementation of requests from the Joint Norwegian Russian

Joint ecosystem surveys in autumn

• Norwegian vessels:– G.O. Sars – Johan Hjort– Jan Mayen

• Russian vessels– Smolensk – Nansen

• Investigations:– Plankton, bottom fish, pelagic fish,

juveniles (0-group), benthos, shrimp, king crab, marine mammals, sea birds, marine chemistry, pollution

Plans for the future:

• Barents Sea – the main focus (continue joint ecosystem cruises to monitor NEA Cod, Capelin, Greenland halibut etc, plankton, crabs and shrimps, benthos, hydrography, pollution)

• Finish Polar Year projects• Climate – ocean accidification• Joint symposias• Exchange of scientists • Joint publications
