Size selectivity and catch efficiency of bottom trawl with a double sorting grid and diamond mesh codend in the North-east Atlantic gadoid fishery
(Peer reviewed; Journal article, 2020)This study investigated the size selectivity and catch efficiency in the North-east Atlantic demersal trawl fishery targeting cod (Gadus morhua) and haddock (Melanogrammus aeglefinus). The use of a sorting grid followed ... -
Size-dependent escape risk of lumpfish (Cyclopterus lumpus) from salmonid farm nets
(Peer reviewed; Journal article, 2020)In the last decade, the salmon aquaculture industry has considerably increased the use of lumpfish juveniles as cleaner fish. Potential escape of reared lumpfish into the wild may spread diseases or genetically contaminate ... -
Size-fractioned zooplankton biomass in the Barents Sea: Spatial patterns and temporal variations during three decades of warming and strong fluctuations of the capelin stock (1989–2020)
(Peer reviewed; Journal article, 2022)Zooplankton biomass has been monitored on joint Norwegian-Russian surveys in late summer and autumn since the 1980s. We report here on zooplankton biomass in three size fractions (<1, 1–2, and > 2 mm in screen mesh opening) ... -
Size-selective harvesting affects the immunocompetence of guppies exposed to the parasite Gyrodactylus
(Peer reviewed; Journal article, 2022)Harvesting is typically size-selective, targeting large individuals. This is expected to lead to reduced average body size and earlier maturation (i.e. faster life histories). Such changes can also affect traits seemingly ... -
Size-selective harvesting alters biological traits of marine medaka (Oryzias melastigma)
(Peer reviewed; Journal article, 2023)Under long-term fishing pressure, the biological traits of many wild fish populations have changed. Such phenotypic changes include smaller in size and earlier age-at-maturation, strongly suggesting that fishing could ... -

Skeletal deformities in wild and farmed cleaner fish species used in Atlantic salmon Salmo salar aquaculture
(Peer reviewed; Journal article, 2020)As a first attempt to assess bone health in cleaner fish production, wild and cultured ballan wrasse Labrus bergylta and lumpfish Cyclopterus lumpus were examined by radiology. In C. lumpus, wild fish (57%) had more vertebra ... -
Skilful prediction of cod stocks in the North and Barents Sea a decade in advance
(Peer reviewed; Journal article, 2021)Reliable information about the future state of the ocean and fish stocks is necessary for informed decision-making by fisheries scientists, managers and the industry. However, decadal regional ocean climate and fish stock ... -
Skillful prediction of Barents Sea ice cover
(Journal article; Peer reviewed, 2015-07-08)A main concern of present climate change is the Arctic sea ice cover. In wintertime, its observed variability is largely carried by the Barents Sea. Here we propose and evaluate a simple quantitative and prognostic framework ... -
