Rapid water temperature variations at the northern shelf of the Yellow Sea
(Peer reviewed; Journal article, 2021)During summer, there is great spatial variability in bottom water temperature on the northern shelf of the Yellow Sea. This variability is associated with a thermal front along the shelf. Oscillatory currents from semidiurnal ... -
Rapport om forsøksfiske etter kolmule vest av De Britiske Øyer i februar-mai 1973
(Journal article, 1973)The experiments were carried out with four boats. Two of a different size working as one boat midwater trawlers and two as a twoboat midwater trawl unit. It is concluded that the spawning stock is dense enough for commercial ... -

Rather-high-frequency sound scattering by swimbladdered fish
(Journal article; Peer reviewed, 1985)A new model describes acoustic scattering by swimbladdered fish of lengths from at least 8 to 36 wavelengths. It represents a fish by an ideal pressure-release surface having the exact size and shape as the swimbladder. ... -
Reaction norm analysis reveals rapid shifts toward delayed maturation in harvested Lake Erie yellow perch (Perca flavescens)
(Journal article; Peer reviewed, 2019)Harvested marine fish stocks often show a rapid and substantial decline in the age and size at maturation. Such changes can arise from multiple processes including fisheries‐induced evolution, phenotypic plasticity, and ... -
Real-Time Ichthyoplankton Drift in Northeast Arctic Cod and Norwegian Spring-Spawning Herring
(Journal article; Peer reviewed, 2011-11-16)Background: Individual-based biophysical larval models, initialized and parameterized by observations, enable numerical investigations of various factors regulating survival of young fish until they recruit into the adult ... -
“Real-time” genetic monitoring of a commercial fishery on the doorstep of an MPA reveals unique insights into the interaction between coastal and migratory forms of the Atlantic cod
(Journal article; Peer reviewed, 2017)With the decline of many of the world’s fisheries, increased regulation, including marine protected areas (MPA), forms an increasingly important role in promoting sustainable resource use. Here, we present a novel “real-time” ... -
Recapture of cultured salmon following a large-scale escape experiment
(Journal article; Peer reviewed, 2010-10-19)A large-scale escape experiment using 1031 adult Atlantic salmon Salmo salar L. was performed in the Hardangerfjord in western Norway to study the dispersal of escaped salmon, evaluate the effect of a gill-net fishery ... -
Recent changes in distribution and relative abundance of cetaceans in the Norwegian Sea and their relationship with potential prey
(Journal article; Peer reviewed, 2015) -
Recent Harp and Hooded Seal Pup Production Estimates in the Greenland Sea Suggest Ecology-Driven Declines
(Peer reviewed; Journal article, 2022)Pup production of the Greenland Sea populations of harp (Pagophilus groenlandicus) and hooded (Cystophora cristata) seals were estimated based upon aerial surveys in March 2018. One fixed-wing aircraft was used for large-area ... -
Recent trend reversal for declining European seagrass meadows
(Journal article; Peer reviewed, 2019)Seagrass meadows, key ecosystems supporting fisheries, carbon sequestration and coastal protection, are globally threatened. In Europe, loss and recovery of seagrasses are reported, but the changes in extent and density ... -
Recent warming and freshening of the Norwegian Sea observed by Argo data
(Journal article; Peer reviewed, 2019)Climate variability in the Norwegian Sea, comprising the Norwegian and Lofoten Basins, was investigated based upon monthly estimates of ocean heat and freshwater contents using data from Argo floats during 2002–18. Both ... -
ReCodLiver0.9: Overcoming Challenges in Genome-Scale Metabolic Reconstruction of a Non-model Species
(Peer reviewed; Journal article, 2020)The availability of genome sequences, annotations, and knowledge of the biochemistry underlying metabolic transformations has led to the generation of metabolic network reconstructions for a wide range of organisms in ... -
Recommendations for dietary level of micro-minerals and vitamin D3 to Atlantic salmon (Salmo salar) parr and post-smolt when fed low fish meal diets
(Journal article; Peer reviewed, 2019)Atlantic salmon (Salmo salar) feeds have changed drastically in their composition from being predominantly marine-based to plant-based. This has altered the dietary supply and availability of micro-nutrients to Atlantic ... -
Recommendations on methods for the detection and control of biological pollution in marine coastal waters
(Journal article; Peer reviewed, 2011-09)Adverse effects of invasive alien species (IAS), or biological pollution, is an increasing problem in marine coastal waters, which remains high on the environmental management agenda. All maritime countries need to assess ... -
Reconstructing the stock–recruit relationship for Northeast Arctic cod using a bioenergetic index of reproductive potential
(Journal article; Peer reviewed, 2000)Correlation and simulation analyses suggest that, for the Northeast Arctic (NA) cod stock, the total lipid energy (TLE (kJ)) contained in the livers of mature females is proportional to total egg production, making TLE a ... -
Reconstruction of the birth of a male sex chromosome present in Atlantic herring
(Peer reviewed; Journal article, 2020)The mechanisms underlying sex determination are astonishingly plastic. Particularly the triggers for the molecular machinery, which recalls either the male or female developmental program, are highly variable and have ... -
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 ... -
