First recorded occurrence of the parasitic barnacle (Anelasma squalicola) on a Greenland shark (Somniosus microcephalus) in the Canadian Arctic
(Journal article; Peer reviewed, 2023)A solitary Anelasma squalicola specimen was collected from the cloaca of a Greenland shark (Somniosus microcephalus), the first time this association has been recorded. The specimen's identity was confirmed through ... -
First reports of a mass mortality event across multiple life stages in a mesopelagic jellyfish in high latitude coastal waters
(Peer reviewed; Journal article, 2018-04)Mass mortality events can occur naturally and may have important ecological impacts on local populations. The abundance and stage structure of the coronate scyphozoan Periphylla periphylla in a Northern Norwegian fjord ... -
First results of turbulence measurements in a wind park with the Small Unmanned Meteorological Observer SUMO
(Peer reviewed; Journal article, 2012-01)The Small Unmanned Meteorological Observer (SUMO), equipped with a miniaturized 5-hole probe for turbulent flow measurements with 100 Hz temporal resolution, has for the first time been operated in and around a wind farm. ... -
First study of the two-body scattering involving charm hadrons
(Journal article; Peer reviewed, 2022)This article presents the first measurement of the interaction between charm hadrons and nucleons. The two-particle momentum correlations of pD− and ¯pD+ pairs are measured by the ALICE Collaboration in high-multiplicity ... -
First Things First: Vital Protein Marks by N-Terminal Acetyltransferases
(Peer reviewed; Journal article, 2016-09)N-terminal (Nt) acetylation is known to be a highly abundant co-translational protein modification, but the recent discovery of Golgi- and chloroplast-resident N-terminal acetyltransferases (NATs) revealed that it can also ... -
Fish feed as source of potentially allergenic peptides from the fish parasite Anisakis simplex (s.l.)
(Peer reviewed; Journal article, 2015-04)The carry-over of certain feed components into animal products can be of concern for human health. The safety assessment of chemical contaminants including natural toxins, agrochemicals, veterinary drugs, and environmental ... -
Fish for food and nutrition security in Ghana: Challenges and opportunities
(Journal article; Peer reviewed, 2020)Fish is an important dietary source of micronutrients, particularly in low-and middle-income countries. In Ghana, effective management of fish and the fisheries is essential for food, economic and nutrition security and ... -
A fish introduction and its impact on the plankton community
(Doctoral thesis, 2012-08-20)This thesis is about how one species can invade an ecosystem and change the whole biological community within a few years. The question is whether such changes can be foreseen or are more or less unpredictable? Biological ... -
Fish louse and treatment options: A mathematical approach

The Fish Pathogen "Candidatus Clavichlamydia salmonicola" - A Missing Link in the Evolution of Chlamydial Pathogens of Humans
(Journal article; Peer reviewed, 2023)Chlamydiae like Chlamydia trachomatis and Chlamydia psittaci are well-known human and animal pathogens. Yet, the chlamydiae are a much larger group of evolutionary ancient obligate intracellular bacteria that includes ... -
Fish protein hydrolysates based on Atlantic salmon by-products. Enzyme cost-efficiency and characterization of sensory, surface-active and nutritional properties
(Doctoral thesis, 2016-06-21)The world fisheries and fish farming industries generate large amounts of by-products after the primary processing of fish to edible products. In Norway alone, this accounted for almost 900,000 tons in 2014. Based on present ... -
Fish resist temptation from junk food: state-dependent diet choice in reproductive Atlantic cod Gadus morhua facing seasonal fluxes of lipid-rich prey
(Journal article; Peer reviewed, 2022)In ecological sciences, animal diets are often simplified to ‘resources' or ‘caloric quantities'. However, in the present study, we investigated the optimal foraging strategy of Atlantic cod Gadus morhua when both macro- ... -
Fish zona radiata (eggshell) protein: A sensitive biomarker for environmental estrogens
(Peer reviewed; Journal article, 1997-04)Environmental estrogens have recently caused great concern because of their ability to mimic natural hormones and influence vital endocrine functions in humans and wildlife. The induction of vitellogenin (Vtg) synthesis ... -
Fisheries in the Drylands of Sub-Saharan Africa – “Fish come with the rains”. Building resilience for fisheries-dependent livelihoods to enhance food security and nutrition in the drylands
(FAO Fisheries and Aquaculture Circulars ; 1118, Book, 2016)Dryland areas cover more than half of sub-Saharan Africa and are home to nearly 50 percent of its populations, who depend on agriculture (including livestock, crops and fisheries) as their main livelihood strategy. Sporadic ... -
