The 1983 year class of Norwegian spring spawning herring as juveniles and recruit spawners
(PINRO-IMR Symposium, Conference object, 1990)This paper gives the geographical distribution and the migrations of the 1983 year class of Norwegian spring spawning herring in the period 1983-1989. These migrations are compared with herring migrations of earlier ... -
20th anniversary of the PINRO-IMR cooperation in the investigations of fish feeding in the Barents Sea: results and perspectives
(IMR/PINRO Joint Report Series, Conference object, 2007)Since 1986 the Institute of Marine Research, (IMR), Norway and the Knipovich Polar Research Institute of Marine Fisheries and Oceanography (PINRO), Russia, have carried out a joint research program on the trophic relationships ... -
Abundance and distribution of 0-group Arcto-Norwegian cod and haddock 1965 - 1982
(PINRO-IMR Symposium, Conference object, 1984)The trawl data from the International 0-group fish surveys in the Baretns Sea are reanalysed for cod and haddock. Relative indices of yearclass abundance are estimated on a logarithmic scale. The most abundant yearclasses ... -

Acoustic estimates of 0-group fish abundance in the Barents Sea and adjacent waters in 1992 and 1993
(PINRO-IMR Symposium, Conference object, 1995)Acoustic and biological data collected during the international O-group surveys in 1992 and 1993 were used to estimate the abundance of O-group fish of 4 species; cod, haddock, redfish and polar cod. The abundances of ... -
Acoustic estimates of abundance-at-age of juvenile Norwegian spring-spawning herring (Clupea harengus L.) in the Barents Sea from 1983 to 1993
(PINRO-IMR Symposium, Conference object, 1995)The first year-class of Norwegian spring-spawning herring to enter the Barents Sea in significant numbers since the stock collapse in the late 1960'ies was the 1983-cohort. Regular acoustic surveys have been carried out ... -
Acoustic estimates of spawning cod in the Lofoten area in 1982 and 1983
(PINRO-IMR Symposium, Conference object, 1984)The main spawning grounds for Arctic cod, the Lofoten area, were covered by acoustic surveys 7 times in 1983 and 12 times in 1983 during the prespawning and spawning season. The results indicated a spawning stock in the ... -
Acoustic stock measurements of the Barents Sea capelin 1972 - 1984: a review
(PINRO-IMR Symposium, Conference object, 1985)This paper gives a review of the procedures currently used to obtain acoustic estimates of the Barents Sea capelin stock, as well as the development history of the procedures, their theoretical and technical basis, and ... -

An approach to estimate the daily ration of cod during intensive feeding based on 24 hour fishery
(PINRO-IMR Symposium, Conference object, 1992)A model descnbing gashic evacuation developed by dos Santos (1990) using a modified version of the power exponential model for stomach evacuation is applied to the Northeast Arctic cod stomachs collected during 24 hour ... -
Assessment and management of Barents Sea capelin
(PINRO-IMR Symposium, Conference object, 1985)The history of the Barents Sea capelin fishery and fishery regulations is reviewed. Basic assessment data and theories are described and discussed in the light of the population dynamics governing the sustainable yield. -
Barents Sea red king crab (Paralithodes camtschatica): a review and discussion of sampling methods
(PINRO-IMR Symposium, Conference object, 1997)Stock assessments for Barents Sea red king crab are based on catch and effort data from research vessel surveys and trial fishery. Different rnethods can be used for sampling red king crab abundance, such as trawl, traps ... -

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
