Monitoring of commercial fish stocks in the Barents Sea

Updated 2012-07-27

This is a cooperation between Institute of Marine Research (IMR) in Norway (contact person Ingolf Røttingen, ingolf.rottingen@imr.no) and Polar Research Institute of Marine Fisheries and Oceanography (PINRO) in Russia. Main objective of the network: - Determine amount and distribution of commercial fish stocks - Describe abundance of biodiversity (benthos, fish, whale, zooplankton, phytoplankton, shellfish) - Determine annual variation in commercial fish biomass and feeding conditions for these fish species. Location: Southern and central Barents Sea – mainly in Norwegian sector. When operational: Area surveys are conducted throughout the year. The number of vessels in each survey differs, not only between surveys but may also change from year to year for the same survey. However, most surveys are conducted with only one vessel. It is not possible to measure all ecosystem components during each survey. Effort is always put on measuring as many species as possible on each survey, but available time put restrictions on what is possible to accomplish. Also, an investigation should not take too long time in order to give a synoptic picture of the conditions. Therefore the surveys must focus on a specific set of species. Other measured species may therefore not have optimal coverage and thereby increased uncertainty, but will still give important information. An overview of the measured species on each main survey is given in the table above. Operation: Observations are taken by IMR from research vessels. The programme is carried out in cooperation with Russia (PINRO) coordinated under the Joint Norway-Russia Fisheries Commission. Assessment of commercial stocks are conducted through ICES. Geographical coverage: Norwegian EEZ of Barents Sea including waters around Svalbard. The joint programme with Russia covers much of the Barents Sea (southern, central, and much of northern part in fall). Network type: Surveys, annual stock assessments
