Investigations on capelin larvae off Northern Norway and in the Barents Sea in 1981-84
(PINRO-IMR Symposium, Conference object, 1985)This report gives a detailed description of the sampling technique, employing the Gulf III plankton sampler. The collected data are displayed on distribution maps, which show both the total abundance of capelin larvae and ... -
Life history and exploitation of the Norwegian spring spawning herring
(PINRO-IMR Symposium, Conference object, 1990)This paper is a review of the history and exploitation of the Norwegian spring spawning herring stock. In a virgin state the biomass of this stock may have ranged from 15 to 20 million tonnes and it was the most important ... -
Long term bilateral Russian-Norwegian scientific co-operation as a basis for sustainable management of living marine resources in the Barents Sea : proceedings of the 12th Norwegian-Russian Symposium, Tromsø, 21-22 August 2007
(IMR/PINRO Joint Report Series, Research report, 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 ... -
Long term changes of growth and maturation in the Norwegian spring spawning herring
(PINRO-IMR Symposium, Conference object, 1990)Two periods with great differences i n year class abundance and recruitment where chosen for growth and maturation studies, 1950 - 1960 and 1973 - 1983. In the first period, the mean year class strength at 3 years was ... -

Maturity studies of Barents Sea capelin: Variations in length at maturity for female capelin
(PINRO-IMR Symposium, Conference object, 1985)The sexual maturation of female capelin in the Barents Sea is studied using a new method based on microscope investigation of eggs. A "length at maturity" (L) is defined, and a method for synthesizing the data is ... -
A method for estimation of predation mortalities on capelin using a cod-capelin model for the Barents Sea
(PINRO-IMR Symposium, Conference object, 1992)The Barents Sea capelin stock coliapsed during the period 1983-1986. One of the main factors causing the colIapse was a rapid increase in consumption of capelin by cod, caused by the strong 1983 cod year class. Based ... -
Methods and results in the joint PINRO-IMR stomach sampling program
(PINRO-IMR Symposium, Conference object, 1992)In 1984IMR started a stomach samling program om cod (Gadus morhua) in the Barents Sea. The aim of the program was to provide the multispecies model with the quantitative data on the cod's food selection. Later other species ... -
Methods of index calculation and presentation of fish abundance data using standard computer programs
(PINRO-IMR Symposium, Conference object, 1995)Standard 0-group indices distribution maps are now produced based on hand-drawn maps using AutoCad with some additional procedures. This paper briefly describes the mathod. The paper further describes ways of importing ... -

Migration, mingling and homing of North-East Arctic cod from two separated spawning grounds
(PINRO-IMR Symposium, Conference object, 1984)Migration of mature North-east Arctic cod tagged in 1975 and 1979-81 on two different spawning areas were studied. The numbers tagged were 11,500 in Lofoten and 3,350 off More, of which 1,088 and 476 recaptures are ... -
Modelling age-dependent natural mortality of juvenile Norwegian spring-spawning herring (Clupea harengus L.) in the Barents Sea
(PINRO-IMR Symposium, Conference object, 1995)Understanding the patterns of mortality in the juvenile stages is essential for improving current stock assessment procedures. A crucial aspect is at which stage in the life cycle of fish is year-class strength determined. ... -
