Cascading effects of temperature alterations on trophic ecology of European grayling (Thymallus thymallus)
(Journal article; Peer reviewed, 2019)The aims of this project were to study: diet composition, food selectivity and the phenology of different prey items in grayling’s (Thymallus thymallus) diet. It was hypothesized, that alterations in mayfly emergence, ... -
A catalog of microbial genes from the bovine rumen unveils a specialized and diverse biomass-degrading environment
(Peer reviewed; Journal article, 2020)Background The rumen microbiota provides essential services to its host and, through its role in ruminant production, contributes to human nutrition and food security. A thorough knowledge of the genetic potential of rumen ... -
Catch and release angling for sea trout explored by citizen science: Angler behavior, hooking location and bleeding patterns
(Peer reviewed; Journal article, 2022)Sea trout (anadromous brown trout, Salmo trutta L.) is a popular target species for angling in Denmark and many other countries. In most regions, angling for sea trout is regulated by measures such as minimum landing sizes, ... -
Catch Control in the Blue Whiting Pelagic Trawl Fishery - Research Cruise Report [2022825]: FV “Vikingbank”
(Toktrapport;2023 - 1, Research report, 2023)This cruise has demonstrated that the catch limitation system can successfully limit catches in the blue whiting pelagic trawl fishery, with negligible loss during the fishing operation while effectively releasing excessive ... -
Catch pattern and size selectivity for a gear designed to prevent fish injuries during the capture process in a North-East Atlantic demersal trawl fishery
(Peer reviewed; Journal article, 2020)In the North-East Atlantic demersal trawl fishery targeting cod and haddock, the interest on fishing gear designs that preserve fish quality and welfare has grown. However, the gear configurations tested so far imply ... -
Catches in abandoned snow crab (Chionoecetes opilio) pots in the Barents Sea
(Peer reviewed; Journal article, 2021)During a 2018 retrieval cruise for abandoned snow crab (Chionoecetes opilio) pots in the Barents Sea, approximately 8600 pots abandoned 1.5 years earlier were recovered. Forty-three percent of a subsample of 1000 pots ... -

Caught in broad daylight: Topographic constraints of zooplankton depth distributions
(Journal article; Peer reviewed, 2018)For visual predators, sufficient light is critical for prey detection and capture. Because light decays exponentially with depth in aquatic systems, vertical movement has become a widespread strategy among zooplankton for ... -
Caught in the trap: over half of the farmed Atlantic salmon removed from a wild spawning population in the period 2014−2018 were mature
(Peer reviewed; Journal article, 2023)Whilst aquaculture continues its global expansion, containment of fish in sea cages remains a persistent environmental challenge. Within Atlantic salmon Salmo salar farming, widespread escapes over several decades have ... -
Causal Drivers of Barents Sea Capelin(Mallotus villosus) Population Dynamics on Different Time Scales
(Journal article; Peer reviewed, 2017)The dynamics of marine populations are usually forced by biotic and abiotic factors occurring at different intensity levels and time scales. Deriving the time frame within which each factor has a causal influence is important ... -
Caveats with estimating natural mortality rates in stock assessment models using age aggregated catch data and abundance indices
(Peer reviewed; Journal article, 2021)We consider the challenge in estimating the natural mortality, M, in a standard statistical fish stock assessment model based on time series of catch- and abundance-at-age data. Though anecdotal evidence and empirical ... -
A century of fish growth in relation to climate change, population dynamics and exploitation
(Peer reviewed; Journal article, 2020)Marine ecosystems, particularly in high‐latitude regions such as the Arctic, have been significantly affected by human activities and contributions to climate change. Evaluating how fish populations responded to past changes ... -
Century-long cod otolith biochronology reveals individual growth plasticity in response to temperature
(Peer reviewed; Journal article, 2020)Otolith biochronologies combine growth records from individual fish to produce long-term growth sequences, which can help to disentangle individual from population-level responses to environmental variability. This study ... -
Challenges Ahead for a Rational Analysis of Vitamin D in Athletes
(Peer reviewed; Journal article, 2021)Vitamin D is an essential vitamin for the normal formation of bones and calcium absorption. It is synthesized into our body through sunlight exposure and obtained by consuming foods rich in vitamin D (e.g., fatty fish, ... -
Changes in benthic sediment conditions under an atlantic salmon farm at a deep, well-flushed coastal site
(Journal article; Peer reviewed, 2014-02-27)Along the Norwegian coastline, it is predicted that salmonid aquaculture will rapidly expand in the coming years, exceeding current production levels of 1.3 million t in 2012. This will result in increased interactions ... -
Changes in daylength and temperature from April until August for Atlantic salmon (Salmo salar) reared in sea cages, increase growth, and may cause consumption of antioxidants, onset of cataracts and increased oxidation of fillet astaxanthin
(Peer reviewed; Journal article, 2022)The hypothesis of the present study was that increased growth in spring, stimulated by increasing temperature and daylength, leads to oxidative stress in Atlantic salmon with accumulation of oxidation products in the tissues ... -
Changes in humpback whale song structure and complexity reveal a rapid evolution on a feeding ground in Northern Norway
(Peer reviewed; Journal article, 2022)Singing behaviour by male humpback whales (Megaptera novaeangliae) has traditionally been associated with low-latitude breeding grounds. However, in recent years, this vocal behaviour has been increasingly reported outside ... -
Changes in Sea-Ice Protist Diversity With Declining Sea Ice in the Arctic Ocean From the 1980s to 2010s
(Peer reviewed; Journal article, 2020)The large declines in Arctic sea-ice age and extent over the last decades could have altered the diversity of sea-ice associated unicellular eukaryotes (referred to as sea-ice protists). A time series from the Russian ... -
