Contemporary ocean warming and freshwater conditions contribute to delay the completion of maturation in Atlantic salmon
Otero, Jaime; Jensen, Arne J.; L’Abée-Lund, Jan Henning; Stenseth, Nils Christian; Storvik, Geir; Vøllestad, Leif Asbjørn (ICES CM documents;2010/S:13, Working paper, 2010)The completion of maturation in Atlantic salmon (Salmo salar) depends on environmental conditions that affect both feeding opportunities and growth, which would provide sufficient lipid stores for reproduction. However, ... -
Environmental effects on ocean entry of Atlantic salmon (Salmo salar) smolt across its range of distribution
Otero, Jaime; Antonsson, T.; Armstrong, J.; Arnason, F.; Arnekleiv, J.V.; Baglinière, J.-L.; Caballero, P.; Castro-Santos, T.; Dempson, J. Brian; Erkinaro, Jaakko; Gudjonsson, S.; Horton, G.; Hvidsten, N.A.; Jensen, Arne J.; Jokikokko, E.; Jonsson, I.R.; Kocik, J.F.; L’Abée-Lund, Jan Henning; Lamberg, A.; Letcher, B.H.; Niemelä, Eero; Romakkaniemi, A.; Russell, I.; Stenseth, Nils Christian; Storvik, Geir; Veselov, A.J.; Vøllestad, Leif Asbjørn (ICES CM documents;2010/S:26, Working paper, 2010) -
Estimating catch-at-age by combining data from different sources
Hirst, David; Storvik, Geir; Aldrin, Magne; Aanes, Sondre; Huseby, Ragnar Bang (Journal article; Peer reviewed, 2005)Estimating the catch-at-age of commercial fish species is an important part of the quota-setting process for many different species and almost all countries with a fishing fleet. Current procedures are usually very ... -
Estimating catch-at-age from market sampling data using a Bayesian hierarchical model
Hirst, David; Tvete, Ingunn Fride; Storvik, Geir; Aanes, Sondre (ICES CM documents, Working paper, 2001) -
Factors affecting year-to-year and within river variability of one-sea-winter Atlantic salmon in Norwegian rivers
Otero, Jaime; Jensen, Arne J.; L’Abée-Lund, Jan Henning; Stenseth, Nils Christian; Storvik, Geir; Vøllestad, Leif Asbjørn (ICES CM documents;2009/E:14, Working paper, 2009)Many Atlantic salmon, Salmo salar, populations are decreasing throughout its distributional range due to several factors acting in concert. A number of studies have documented the influence of freshwater and ocean ... -
Fish and oil in the Lofoten–Barents Sea system: synoptic review of the effect of oil spills on fish populations
Hjermann, Dag Ø.; Melsom, Arne; Dingsør, Gjert Endre; Durant, Joël M.; Eikeset, Anne Maria; Røed, Lars Petter; Ottersen, Geir; Storvik, Geir; Stenseth, Nils Christian (Journal article; Peer reviewed, 2007-06-06)The Lofoten-Barents Sea area, which contains some of the most valuable fish stocks of the Atlantic Ocean, is being considered for offshore oil production. We review the effects of a hypothetical oil spill on fishes in this ... -
Improving management decisions by predicting fish bycatch in the Barents Sea shrimp fishery
Aldrin, Magne; Mortensen, Bjørnar; Storvik, Geir; Nedreaas, Kjell Harald; Aglen, Asgeir; Aanes, Sondre (Journal article; Peer reviewed, 2011-11-20)When the bycatch of juvenile fish within the Barents Sea shrimp fishery is too large, the area is closed to fishing for a certain period. Bycatch is estimated from sampled trawl hauls, for which the shrimp yield is recorded, ... -
Quantifying the Ocean, Freshwater and Human Effects on Year-to-Year Variability of One-Sea-Winter Atlantic Salmon Angled in Multiple Norwegian Rivers
Otero, Jaime; Jensen, Arne J.; L’Abée-Lund, Jan Henning; Stenseth, Nils Christian; Storvik, Geir; Vøllestad, Leif Asbjørn (Journal article; Peer reviewed, 2011-08-29)Many Atlantic salmon, Salmo salar, populations are decreasing throughout the species' distributional range probably due to several factors acting in concert. A number of studies have documented the influence of freshwater ...
