Capelin and herring as key species for the yield of cod: Results from multispecies model runs
(IMR/PINRO Joint Report Series, Conference object, 2002)A conceptual multispecies model for the fishery of capelin, cod and herring (Systmod) in the Norwegian Sea-Barents Sea region has been developed and used in analysing the impact of different fishery management strategies ... -
The capelin assessment model: a documentation
(PINRO-IMR Symposium, Conference object, 1985)The mathematical model used for management of the Barents Sea is documented. The model is used for predicting the evolution of the stock to evaluate the consequence of various catch quotas. -
Capelin in the Barents Sea
(IMR/PINRO Joint Report Series, Conference object, 2004)The report discusses the past and present management of the Barents Sea capelin stock. It also provides a short recapitulation of stock characteristics and the history of the stock and fishery. -
Causes of trends and fluctuations in the Arcto-Norwegian stock
(ICES Marine Science Symposia, Conference object, 1994)Published information is used to review trends and fluctuations in landings and stock characteristics/variables (abundance, growth, maturation, distribution, and migrations) in relation to changes in environmental and ... -
Climate change and effects on the Barents Sea marine living resources : 15th Russian-Norwegian Symposium Longyearbyen, 7-8 September 2011

Climate variations and the state of zooplankton in the Barents Sea
(IMR/PINRO Joint Report Series;5/2007, Conference object, 2007)We present data on zooplankton biomass distribution in August-September 2005-2006 obtained in the integrated ecosystem system survey for the Barents Sea performed by Russian and Norwegian vessels. In order to establish ... -

Climatic variations in the Barents Sea
(PINRO-IMR Symposium, Conference object, 1987)The eireulation system of the Barents Sea is described. Warm water flows into the sea from west and is gradually transformed into Artic waters flowing out from the sea, partly as surface currents, partly as dense bottom ... -
Cod in the Barents Sea (North-East arctic cod) : a review of the biology and the history of fishery and management [presentation]

Cod in the Barents Sea (Northeast Arctic cod): a review of the biology and history of the fishery and its management
(IMR/PINRO Joint Report Series, Conference object, 2004)This paper briefly reviews our knowledge of the spatial distribution, ecology, stocks dynamics and fishery for Northeast Arctic cod. The history of stock assessments and scientific advice, and of fisheries regulations and ... -
A comparison between abundance estimates of the Barents Sea capelin at the larval, 0-group and 1-group stage in the period 1981-1991
(PINRO-IMR Symposium, Conference object, 1995)A larval abundance estimate, obtained during a Norwegian survey in June, an 0-group index, obtained during the International 0-group survey in August, and an acoustic 1-group estimate, obtained during the IMR/PINRO ... -
Comparison of the capture efficiency of 0-group fish in pelagic trawls
(PINRO-IMR Symposium, Conference object, 1995)In 1992 and 1993 experiments were carried out during the international 0-group fish surveys in order to study the capture efficiency of two pelagic trawls. The catches of the standard sampling trawl were compared with ... -
Comparisons between size distribution in surveys and commercial catches: a useful tool for monitoring changes in the size selection in the fisheries?
(IMR/PINRO Joint Report Series, Conference object, 2001)A method is proposed for using fish distributions from standarized research surveys for estimating relative selection in the fisheries. The method is applied on data for North-east arctic cod in the 1990-ies. Survey-related ... -
The daily feeding dynamics in various length groups of the Barents Sea capelin
(PINRO-IMR Symposium, Conference object, 1992)A total of 692 capelin stomachs collected in the Goose Bank area in August 1989 by 24 hour fishery were analyzed by 3 cm capelin length groups. The nwnber of prey categories consumed by the Barents Sea capelin showed a ... -
Daily rations of cod from the Barents Sea
(PINRO-IMR Symposium, Conference object, 1992)Diurnal feeding rhythms and daily diets of the North-East Arctic cod were investigated based on data obtained at several stations made in the summer of 1988-1989. A well-pronounced feeding rhythmicity was recorded under ... -
The dependence of management strategies for Barents Sea cod and capelin on the recruitment models
(PINRO-IMR Symposium, Conference object, 1995)The least studied subject in the assessment and management of Barents Sea cod and capelin is the management strategy. Using a cod-capelin-herring model, the uncertainty in the management strategy of cod and capelin arising ... -
