Some environmental factors that influence the growth of Arcto-Norwegian cod from the early juvenile to the adult stage
Helle, Kristin; Bogstad, Bjarte; Ottersen, Geir; Pennington, Michael (ICES CM documents, Working paper, 2000)A high growth rate for Arcto-Norwegian cod (Gadus morhua L.) in the Barents Sea and adjacent areas from the larval stage to the 0-group stage enhances survival and ultimately recruitment to the fishery. However, it appears ... -
Spatial patterns of age-0 cod survival in the Barents Sea
Ciannelli, Lorenzo; Dingsør, Gjert Endre; Bogstad, Bjarte; Ottersen, Geir; Chan, Kung-Sik; Gjøsæter, Harald; Stenseth, Nils Christian (ICES CM documents, Working paper, 2005)Apart from human harvest, recruitment dynamics is conceivably recognized as the main source of population variability of marine fish stocks. Factors affecting recruitment dynamics can change over both temporal and spatial ... -

The choice of TAC when faced with multiple objectives
Sandberg, Per; Bogstad, Bjarte; Røttingen, Ingolf; Veim, Anne Kjos (ICES CM Documents;1996/P:15, Working paper, 1996)The total allowable catch is a key instrument in fishery management, and advice on its level used to be based purely on biology.

Bogstad, Bjarte; Mehl, Sigbjørn (ICES CM Documents;1990/G:22, Working paper, 1990)The consumption rates in fish are important but also often weak points in multispecies models.
