Osmotic cataract causes reduced vision in wild Atlantic salmon postsmolts
(Journal article; Peer reviewed, 2003-07-08)Osmotic cataracts were diagnosed in all of 191 Atlantic salmon Salmo salar L. postsmolts caught during 8 trawl hauls on the western side of the Vøringsplateau, Norwegian Sea, in June 2001. The changes varied from a hazy ... -
Ossification of Atlantic cod (Gadus morhua) – Developmental stages revisited
(Peer reviewed; Journal article, 2017)In studies of marine larvae, it is common to use days post-hatch as a developmental reference point. We show that age is a poor measure of morphological and physiological development in Atlantic cod. Therefore, we propose ... -

Other Effective Area-based Conservation Measures – OECMs: Andre effektive arealbaserte bevaringstiltak - Gjennomgang av noen norske arealbaserte fiskeriforvaltningstiltak og deres bidrag til bevaring av marin natur
(Rapport fra havforskningen;2023 - 45, Research report, 2023)I 2010 vedtok partsmøtet under konvensjonen om biologisk mangfold (CBD) bevaringsmål for natur der det blant annet het at 10% av hav- og kystområder skulle bevares innen 2020. Dette målet skulle kunne nås ad to veier: ... -

Otolith δ13C values as a metabolic proxy: Approaches and mechanical underpinnings
(Journal article; Peer reviewed, 2019)Knowledge of metabolic costs associated with maintenance, foraging, activity and growth under natural conditions is important for understanding fish behaviours and the bioenergetic consequences of a changing environment. ... -
Otolith “spawning zones” across multiple Atlantic cod populations: Do they accurately record maturity and spawning?
(Peer reviewed; Journal article, 2021)Specific changes identified in the otolith macrostructure of Northeast Arctic cod as “spawning zones” are presumed to represent spawning events, but recent experimental studies have challenged this relationship. Because ... -
Otolittreferansesamling for lodde (Mallotus villosus) i Barentshavet
(Fisken og havet;5-2011, Research report, 2011-06)In 2007 a project was initiated at the Institute of Marine Research, Bergen, with the aim to further develop the methods for age determination of fish by their otoliths, as well as to assure the quality of routine age ... -

Out-of-season spawning affects the nutritional status and gene expression in both Atlantic salmon female broodstock and their offspring
(Peer reviewed; Journal article, 2020)The Atlantic salmon aquaculture industry relies on adjustments of female broodstock spawning season to meet the demand for delivery of embryos outside the natural spawning season. Earlier results from zebrafish have shown ... -
Outflow of Skagerrak water to the North Sea during summer 1984
(ICES CM Documents;1985/C:21, Working paper, 1985)This paper describes a situation from summer 1984 where low salinity water from the Skagerrak was flowing west and north and covered a significant part of the northern North Sea Plateau. This unusually Skagerrak water ... -

Overexploitation, Recovery, and Warming of the Barents Sea Ecosystem During 1950–2013
(Peer reviewed; Journal article, 2021)The Barents Sea (BS) is a high-latitude shelf ecosystem with important fisheries, high and historically variable harvesting pressure, and ongoing high variability in climatic conditions. To quantify carbon flow pathways ... -
Overexpression of cyclooxygenase-2 in adipocytes reduces fat accumulation in inguinal white adipose tissue and hepatic steatosis in high-fat fed mice
(Journal article; Peer reviewed, 2019)Cyclooxygenases are known as important regulators of metabolism and immune processes via conversion of C20 fatty acids into various regulatory lipid mediators, and cyclooxygenase activity has been implicated in browning ... -
Overflytting av torsk fra Finnmarkskysten til Stadhavet
(Fisken og havet;1963 - Nr. 4, Journal article, 1963)The geographical distribution of the recoveries of cod caught the 19th October 1959 at the Finnmark Coast and released the 23rd October the same year at Stad is studied. The migration northwards to the Lofoten area just ... -
