20th anniversary of the PINRO-IMR cooperation in the investigations of fish feeding in the Barents Sea: results and perspectives
Dolgov, Andrey V.; Yaragina, Natalia A.; Orlova, Emma L.; Bogstad, Bjarte; Johannesen, Edda; Mehl, Sigbjørn (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 ... -

Daily rations of cod from the Barents Sea
Dolgov, Andrey V.; Yaragina, Natalia A.; Ajiad, Adnan Mosa; Mehl, Sigbjørn; Bogstad, Bjarte (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 ... -

An evaluation of the methodology for prediction of capelin biomass
Bogstad, Bjarte; Gjøsæter, Harald; Ushakov, N.G.; Prozorkevich, Dmitry (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 ... -

Interrelations between fish populations in the Barents sea : proceedings of the fifth PINRO-IMR Symposium, Murmansk, 12-16 August 1991

A method for estimation of predation mortalities on capelin using a cod-capelin model for the Barents Sea
Bogstad, Bjarte; Tjelmeland, Sigurd (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 ... -
The North-East Arctic cod stock's consumption of various prey species 1984-1989
Bogstad, Bjarte; Mehl, Sigbjørn (PINRO-IMR Symposium, Conference object, 1992)The North-East Arctic cod stock's consumption of different prey species has earlier been calculated by Mehl (1989) for the period 1984-1986. However, a new model to describe gastric evacuation on cod has now been presented ... -
Prediction of capelin growth for use in CapTool
Bogstad, Bjarte; Dalpadado, Padmini; Gjøsæter, Harald (IMR/PINRO Joint Report Series;2/2005, Conference object, 2005) -
Reconstructing the time series of abundance of Northeast Arctic cod (Gadus morhua), taking cannibalism into account [presentation]
Yaragina, Natalia A.; Bogstad, Bjarte; Kovalev, Yuri (IMR/PINRO Joint Report Series;5/2007, Conference object, 2007) -
Relations between recruitment indices and occurence in cod stomachs of pre-recruits of cod and haddock in the Barents Sea
Bogstad, Bjarte; Mehl, Sigbjørn (PINRO-IMR Symposium, Conference object, 1995)The predation by North-East Arctic cod on pre-recruits of cod and haddock is reviewed based on data from the joint PINRO-IMR stomach content data base. It is investigated how the abundance indices from surveys of pre-recruits ... -
Variability in cannibalism in Northeast Arctic cod (Gadus morhua L.) during the period 1947-2006
