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 ... -
Fisheries Surveys Are Essential Ocean Observing Programs in a Time of Global Change: A Synthesis of Oceanographic and Ecological Data From U.S. West Coast Fisheries Surveys
(Journal article; Peer reviewed, 2022)As climate change and other anthropogenic impacts on marine ecosystems accelerate in the 21st century, there is an increasing need for sustained ocean time series. A robust and collaborative network of regional monitoring ... -
Fisheries, the inverted food pyramid
(Peer reviewed; Journal article, 2015-12-13)A global assessment of fishing patterns and fishing pressure from 110 different Ecopath models, representing marine ecosystems throughout the world and covering the period 1970–2007, show that human exploitation across ... -
Fisheries-induced evolution
(Peer reviewed; Journal article, 2015-12)Increased mortality from fishing is expected to favor faster life histories, realized through earlier maturation, increased reproductive investment, and reduced postmaturation growth. There is also direct and indirect ... -
Fisheries-induced evolution in morphology: a selection experiment on the Trinidadian guppy (Poecilia reticulata)
(Master thesis, 2016-06-01)For the past century, the human population has been growing, and the human technology has been advancing, both at historically-unprecedented rates. As a result, the overall impact of human activities on the lives and deaths ... -
Fishes in a changing world: learning from the past to promote sustainability of fish populations
(Journal article; Peer reviewed, 2018)Populations of fishes provide valuable services for billions of people, but face diverse and interacting threats that jeopardize their sustainability. Human population growth and intensifying resource use for food, water, ... -

Fishmeal physicochemical properties. Impact on the fish feed extrusion process, phase transitions and physical pellet quality
(Doctoral thesis, 2015-06-19)Norway is the world largest producer of Atlantic salmon (Salmo salar). In 2013 the Norwegian aquaculture industry produced 1.2 million metric tons salmon with the use of 1.5 million metric tons of commercial feeds. The ... -
Five reasons to take the precautionary approach to deep sea exploitation
(Journal article, 2023)Extractive activities in the deep sea are poised to advance faster than the science needed to evaluate risks. Here, we call for a strong precautionary approach in developing these industries. -
Five-weight codes from three-valued correlation of M-sequences
(Journal article; Peer reviewed, 2023)In this paper, for each of six families of three-valued m-sequence correlation, we construct an infinite family of five-weight codes from trace codes over the ring R = F2 + uF2, where u2 = 0. The trace codes have the ... -
Fixed Bed Reactor Validation of a Mayenite Based Combined Calcium–Copper Material for Hydrogen Production through Ca–Cu Looping
(Peer reviewed; Journal article, 2019-07-15)For the first time, a mayenite based material combining calcium and copper (18.0/37.6/44.4 estimated active wt % CaO/CuO/Ca12Al14O33, CuO/CaO = 2.1 [wt/wt]) has been subjected to three full calcium–copper chemical looping ... -
Fixed cardinality stable sets
(Journal article; Peer reviewed, 2021)Given an undirected graph G=(V,E) and a positive integer k in {1, ..., |V|}, we initiate the combinatorial study of stable sets of cardinality exactly k in G. Our aim is to instigate the polyhedral investigation of the ... -

A Fixed-Parameter Perspective on #BIS
(Peer reviewed; Journal article, 2019-07-18)The problem of (approximately) counting the independent sets of a bipartite graph (#BIS) is the canonical approximate counting problem that is complete in the intermediate complexity class #RHΠ1. It is believed that #BIS ... -
The Fixed-Stress splitting scheme for Biot's equations as a modified Richardson iteration: Implications for optimal convergence
(Journal article; Peer reviewed, 2021)The fixed-stress splitting scheme is a popular method for iteratively solving the Biot equations. The method successively solves the flow and mechanics subproblems while adding a stabilizing term to the flow equation, which ... -
