A comparison between abundance estimates of the Barents Sea capelin at the larval, 0-group and 1-group stage in the period 1981-1991
Gundersen, Agnes C.; Gjøsæter, Harald (PINRO-IMR Symposium, Conference object, 1995)A larval abundance estimate, obtained during a Norwegian survey in June, an 0-group index, obtained during the International 0-group survey in August, and an acoustic 1-group estimate, obtained during the IMR/PINRO ... -
Early development of Northeast Arctic greenland halibut (Reinhardtius hippoglossoides)
Stene, Anne; Gundersen, Agnes C.; Albert, Ole Thomas; Solemdal, Per; Nedreaas, Kjell Harald (ICES CM Documents;1998/O:27, Working paper, 1998)The early development of the Greenland halibut (Reinhardtius hippoglossoides) has never been described in detail. This study contains some preliminary notes on the egg development of the Northeast Arctic Greenland halibut ... -
Electronic catch registration onboard commercial fishing vessels for commercial and scientific use
Gundersen, Agnes C.; Dyb, Jan Erik; Boje, Jesper; Hjörleifsson, Einar; Helle, Kristin (ICES CM documents;2009/L:16, Working paper, 2009)In assessment and management of marine fish resources, representative data of statistically good quality describing the actual catch are lacking for many fisheries. Even for the most studied fisheries in the north Atlantic, ... -

Helle, Kristin; Pennington, Michael; Gundersen, Agnes C. (Conference object, 2010-08) -
Fecundity of Greenland halibut (Reinhardtius hippoglossoides) in the north east Arctic
Gundersen, Agnes C.; Kjesbu, Olav Sigurd; Stene, Anne; Nedreaas, Kjell Harald (ICES CM documents, Working paper, 1998) -
Fishery changes and implications - need for a wider approach to address socioeconomical effects in fisheries management
Gundersen, Agnes C.; Helle, Kristin; Nystrand, Bjørn Tore; Oterhals, Oddmund; Kjerstad, Margareth; Yttredal, Else Ragn; Herse, Øyvind (ICES CM Documents;2010/M:27, Conference object, 2010)Probabilistic maturation reaction norms (PMRN) were used to investigate changes in the maturation of sardine cohorts and to discuss whether genetic effects, environmental effects or both are plausible explanations of ... -
Modelling the advection and diffusion of eggs and larvae of Northeast Arctic Greenland halibut
Ådlandsvik, Bjørn; Gundersen, Agnes C.; Nedreaas, Kjell Harald; Stene, Anne; Albert, Ole Thomas (ICES CM documents, Working paper, 1999)In later years there has been considerable uncertainty on the recruitment of the northeast Arctic stock of Greenland halibut (Reinhardtius hyppoglossoides). The abundance of several year classes originally considered ... -
Recent variations in recruitment of Northeast Atlantic greenland halibut (Reinhardtius hippoglossoides) in relation to physical factors
Albert, Ole Thomas; Nilssen, Einar M.; Nedreaas, Kjell Harald; Gundersen, Agnes C. (ICES CM Documents;1997/EE:6, Working paper, 1997)Based on annual bottom trawl surveys in the Barents Sea and Svalbard area in 1983-96, the paper describes variations in abundance and composition of 1-group Greenland halibut (Reinhardtius hippoglossoides). The main ... -
Relative selectivity in trawls, longline and gillnets on Greenland halibut
Huse, Irene; Nedreaas, Kjell Harald; Gundersen, Agnes C. (PINRO-IMR Symposium, Conference object, 1997)Selectivity parameters for Greenland halibut (Reinhardtius hippoglossoides, Walbaum) are compared to catches reported fiom trawl, gillnets and longline in the Norwegian scientific fisheries for Greenland halibut. A trouser ... -
