The record-warm Barents Sea and 0-group fish response to abnormal conditions
(Peer reviewed; Journal article, 2020)The Barents Sea is a nursery area for many commercially and ecologically important fish stocks, and this whole region is presently subject to rapid climatic change from a cold period in the 1980s to a record warm period ... -
Recorded captures of American lobster (Homarus Americanus) in Swedish waters and an observation of predation on the European lobster (Homarus Gammarus)
(Peer reviewed; Journal article, 2017) -
Recovery from exhaustive swimming and its effect on fillet quality in haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 2018)Wild haddock (Melanogrammus aeglefinus) of commercial size (0.8–2.49 kg, 45–60 cm) were swum to exhaustion in a large swim tunnel and then allowed to recuperate for 0, 3 or 6 h, to investigate the effects of exhaustive ... -
Recovery of algal turfs following removal
(Peer reviewed; Journal article, 2023)As a consequence of the increasing human footprint on the environment, marine ecosystems are rapidly transforming into new configurations dominated by early-successional and weedy life forms. Algal turfs, in particular, ... -
Recreational sea fishing in Europe in a global context—Participation rates, fishing effort, expenditure, and implications for monitoring and assessment
(Journal article; Peer reviewed, 2017)Marine recreational fishing (MRF) is a high-participation activity with large economic value and social benefits globally, and it impacts on some fish stocks. Although reporting MRF catches is a European Union legislative ... -
Recruitment regime shifts and nonstationarity are widespread phenomena in harvestable stocks experiencing pronounced climate fluctuations
(Peer reviewed; Journal article, 2023)Methods to reliably identify jump discontinuities in biological time series and to assess the specific contribution of various covariates are rapidly progressing. Here, we took advantage of these statistical improvements ... -
Recruitment variability of fish stocks in the Barents Sea: Spatial and temporal variation in 0-group fish length of six commercial species during recent decades of warming (1980–2017)
(Peer reviewed; Journal article, 2022)Young-of-the-year (0-group) fish in the Barents Sea have been investigated in an annual joint Norwegian-Russian pelagic trawl survey in autumn, using a standardized procedure since 1980. We use a conceptual framework of ... -
Recurrent convergent evolution at amino acid residue 261 in fish rhodopsin
(Journal article; Peer reviewed, 2019)The evolutionary process that occurs when a species colonizes a new environment provides an opportunity to explore the mechanisms underlying genetic adaptation, which is essential knowledge for understanding evolution and ... -
Recycling pathways in cold-water coral reefs: Use of dissolved organic matter and bacteria by key suspension feeding taxa
(Peer reviewed; Journal article, 2020)Cold-water coral (CWC) reefs are one of the most diverse and productive ecosystems in the deep sea. Especially in periods of seasonally-reduced phytodetritus food supply, their high productivity may depend on the recycling ... -
Red and melanized focal changes in white skeletal muscle in Atlantic salmon (Salmo salar): Comparative analysis of farmed, wild and hybrid fish reared under identical conditions
(Peer reviewed; Journal article, 2023)Selective breeding plays a vital role in the production of farmed Atlantic salmon and has shown success in many aspects. Still, challenges related to fish health and welfare continue to result in significant economic losses. ... -
Red and white chinook salmon (Oncorhynchus tshawytscha): Differences in the transcriptome profile of muscle, liver, and pylorus
(Peer reviewed; Journal article, 2020)Astaxanthin (Ax), the main carotenoid responsible for the distinct red flesh color in salmonids (Oncorhynchus, Salvelinus, Salmo, and Parahucho), is added to the diet of farmed fish at a substantial cost. Despite the great ... -
Redescription and new records of Jansen’s goatfish, P. jansenii (Mullidae), from the Western Pacific and Eastern Indian Ocean.
(Journal article; Peer reviewed, 2017)For Jansen’s goatfish, Parupeneus jansenii (Mullidae), taxonomic knowledge has been rather poor and occurrence information restricted to a few localities only, with verified records from northern Sulawesi and Sunda Street ... -
Redningsaksjon for Vossolaksen 2010-2020 -status per 2021

Reduced physiological performance in a free-living coralline alga induced by salmon faeces deposition
(Peer reviewed; Journal article, 2021)Maerl beds are formed by the accumulation of free-living coralline algae and have considerable ecological significance due to the high diversity of associated fauna and flora. The rapid expansion of the Atlantic salmon Salmo ... -
Reference point based management of Norwegian Atlantic salmon populations
(Peer reviewed; Journal article, 2013)While management according to biological reference points is well established for many commercial marine fisheries, similar systems for more leisure based fisheries for freshwater fishes are less common. This paper describes ... -
Refined mackerel oil increases hepatic lipid accumulation and reduces choline and choline-containing metabolites in the liver tissue in mice fed a Western diet
(Peer reviewed; Journal article, 2023)In this study, we aimed to evaluate the impact of consuming refined mackerel oil (MO) from rest raw material on hepatic fat accumulation, glucose tolerance, and metabolomic changes in the liver from male C57BL/6N mice. The ... -
Refining fisheries advice with stock-specific ecosystem information
(Peer reviewed; Journal article, 2021)Although frequently suggested as a goal for ecosystem-based fisheries management, incorporating ecosystem information into fisheries stock assessments has proven challenging. The uncertainty of input data, coupled with the ... -

Regional melt-pond fraction and albedo of thin Arctic first-year drift ice in late summer
(Journal article; Peer reviewed, 2015-02-09)The paper presents a case study of the regional (≈150 km) morphological and optical properties of a relatively thin, 70–90 cm modal thickness, first-year Arctic sea ice pack in an advanced stage of melt. The study combines ...
