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 (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 ... -

Distribution and abundance indices of postlarval and 0-group cod
(PINRO-IMR Symposium, Conference object, 1987)Postlarvae surveys have been carried out in the southwestern part of the Barents Sea and the northeastern part of the Norwegian Sea in June/July since 1971, The aim of the Investigations has been to study characteristic ... -
Distribution and abundance of post larval Northeast Arctic cod and haddock
(PINRO-IMR Symposium, Conference object, 1984)From 1977 onwards an annua1 postlarvae survey has been carried out off northern Norway in June/July. The aim is to study the distribution of fish larvae, and to establish an index for thom 53m to surface. In 1983 the ... -
Distribution and growth of blue whiting in the North-East Atlantic 1980-1988
(PINRO-IMR Symposium, Conference object, 1990)The distribution pattern of the blue whiting spawning stock have gradually changed i n recent years, and concentrations are recorded more offshore and more to the south than before. The activity of the fleet with its ... -
Distribution and number of marine mammals in the open Barents Sea and their connection with capelin and polar cod distribution
(IMR/PINRO Joint Report Series, Conference object, 2005)This paper presents the data on the character of distribution and the assessment of the number of marine mammals in the open part of the Barents Sea in autumn 2001-2004 by the results from PINRO’s aerial surveys using the ... -

The distribution of cod larvae and prey organism in the Lofoten area related to critical prey concentration
(PINRO-IMR Symposium, Conference object, 1984)The distribution of cod larvae and their main prey organisms in the first feeding areas off the Lofoten islands have been studied in sheltered and exposed areas in relation to feeding conditions. These findings are discussed ... -
