The egg production of Arcto-Norwegian cod (Gadus morhua L.) in the Lofoten area estimated by egg surveys
(PINRO-IMR Symposium, Conference object, 1984)Spawning intensity measurements have been executed in Lofoten each year since 1976. They consist of egg net samples at selected spawning cites . In 1983, in addition, four quasi-synoptic egg surveys were conducted during ... -
Estimating the maturity ogitive for Northeast Arctid cod by a modified assessment model
(PINRO-IMR Symposium, Conference object, 1984)The exploitation (1967-77) of the Northeast Arctic cod is splitted in 12 different fisheries. The mesh assessment model is modified in order to estimate the maturity ogive on the basis of the length and the age distributions ... -

An evaluation of the methodology for prediction of capelin biomass
(IMR/PINRO Joint Report Series, Conference object, 2005)The one-year prediction of capelin made as part of the assessment after the annual joint acoustic capelin survey during the autumn, is evaluated. Such predictions were made for the period from 1981 till present, and compared ... -

Experiments with cod pots as an alternative to gill-nets in the Varanger fjord in april-june and october-december 1996
(PINRO-IMR Symposium, Conference object, 1997)A newly developed cod pot (two-chamber pot) has been tested in the VarangerfJord area as an alternative to gill-net, with the purpose to reduce the periodically large unaccounted mortality of king crab in the gill-net ... -
Factors determining the year-class strength of Norwegian spring spawning herring
(PINRO-IMR Symposium, Conference object, 1995)More than 30 years of Russian and Norwegian data on spring-spawning herring larvae along the coast of Norway has been investigated and analyzed together with different environmental parameters and spawning stock size. ... -

Genetic studies on eggs, larvae and 0-group of the Arctic cod stock
(PINRO-IMR Symposium, Conference object, 1984)Genetic analyses have been performed on samples of spawning cod (March) , a large number of eggs and yalk sac 1arvae (May, postlarvae (July) and O-group cod (August-September). The distribution of eggs and larvae at ... -
Growth of the Barents Sea capelin of the yearclasses 1975-1981
(PINRO-IMR Symposium, Conference object, 1985)The method of backcalculating fish lengths based on yearly growth markings in the otoliths is applied to estimate growth of capelin in the yearclasses 1975 to 1981. The Barents Sea is divided into five subareas, and the ...
