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 ... -

Estimation of predation mortalities on capelin using a cod - capelin model for the Barents Sea
Bogstad, Bjarte; Tjelmeland, Sigurd (ICES CM Documents;1990/H:16, Working paper, 1990)The Barents Sea capelin stock collapsed during the period 1983-1986. One of the main factors causing the collapse was a rapid increase in consumption of capelin by cod. Based on measurements of stomach evacuation rates ... -
Evaluation of candidate management plans, with reference to North-East Arctic Cod
Skagen, Dankert W.; Bogstad, Bjarte; Sandberg, Per; Røttingen, Ingolf (ICES CM documents, Working paper, 2003)We here discuss the scope, nature and quality standards of simulation models that may be used in order to evaluate proposed or candidate management plans, including their parameters (reference points). A recently proposed ... -

An evaluation of recruitment indices for Northeast Arctic cod (Gadus morhua L.)
Helle, Kristin; Bogstad, Bjarte; Marshall, C. Tara; Michalsen, Kathrine; Ottersen, Geir; Pennington, Michael (ICES CM documents, Working paper, 1999)Indices of the abundance of Northeast Arctic cod (Gadus morhua L.) for various life stages were compared in order to determine the earliest stage at .which year-class strength is established. The indices considered are: ... -
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 ... -
