Probiotics, lactic acid bacteria and bacilli: interesting supplementation for aquaculture
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-05)
Probiotics administration in aquafeed is known to increase feed consumption and absorption due to their capacity to release a wide range of digestive enzymes and nutrients which can participate in digestion process and feed utilization, along with the absorption of diet components led to an increase in host’s health and well‐being. Furthermore, probiotics improve gut maturation, prevention of ...
Niche separation between two dominant crustacean predators in European estuarine soft-bottom habitats
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-05)
Epibenthic predators in estuarine shallow soft-bottom environments are generally considered to have broad ecological niches with a wide overlap. This allows them to cope with abundant but highly variable prey communities. The assessment of trophic relationships in shallow soft-bottom habitats is, however, challenging and often complicated by the bias and low resolution of the analytical tools available ...
Conceptualizing fishery systems: A mental models approach
(Doctoral thesis; Doktorgradsavhandling, 2022-04-22)
Thinking of fisheries as a system is a relatively new approach in fisheries science and management. As part of my contribution to this perspective, this thesis uses mental models as a new approach to gain insights into how individuals conceptualize fisheries. Mental models are internal representations of the surrounding world (e.g., phenomena, processes, problems) and they are important because these ...
Bakteriell gjellebetennelse hos rognkjeks (Cyclopterus lumpus)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021)
Veterinærinstituttet mottok i januar i år en innsendelse fra et settefiskanlegg for rognkjeks. Rognkjeksen var 10-13 gram og uvaksinert. Settefiskanlegget er et gjennomstrømningsanlegg med sjøvann. Det var mistanke om gjelleproblematikk da det ble rapportert om døde individer med utspilte gjellelokk og bleke gjeller. Ved Veterinærinstituttet ble det gjennomført histopatologiske og immunhistokjemiske ...
Computational Models That Matter During a Global Pandemic Outbreak: A Call to Action
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-31)
The COVID-19 pandemic is causing a dramatic loss of lives worldwide, challenging the sustainability
of our health care systems, threatening economic meltdown, and putting pressure on the mental health of individuals (due to social distancing and lock-down measures). The pandemic is also posing severe challenges to
the scientific community, with scholars under pressure to respond to policymakers’ ...
Antecedents of consumer evaluation and consumption of functional food
(Doctoral thesis; Doktorgradsavhandling, 2021-12-15)
The overall aim of this dissertation is to improve the theoretical and empirical understanding of consumers’ behavioral tendencies toward functional food consumption. The main purpose is to provide a deeper understanding of antecedents that are relevant for explaining consumer evaluation of functional food and consumption behavior. Functional foods are food products that have been enriched to make ...
Salmon louse (Lepeophtheirus salmonis (Krøyer)) control methods and efficacy in atlantic salmon (Salmo salar (Linnaeus)) aquaculture: A literature review
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-31)
The salmon louse (<i>Lepeophtheirus salmonis</i>) causes problems in Atlantic salmon (<i>Salmo salar</i>) aquaculture in the Northern Hemisphere, because infestations can result in both a loss of production and in fish mortality. Several types of treatment have been used to control louse infestations, but these have seen varying success. The aim of this review is to examine the efficacy and safety ...
A synoptic history of the development, production and environmental oversight of hydropower in Brazil, Canada, and Norway
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-17)
Sustainable global energy production is
back-stopped by hydropower which is responsible for
a significant share of the green energy produced
worldwide. Hydropower, however, does not come
without some environmental impacts but has worked
to reduce those impacts. Here, we discuss the historical, legislative, and design configurations of hydropower facilities located in three of the world’s ...
When a year is not enough: Further study of the seasonality of planktonic protist communities structure in an ice-free high arctic fjord (adventfjorden, west spitsbergen)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-07-20)
As a contribution to understanding the ecological framework of protistan seasonal succession patterns, we present the weekly-to-monthly (January–October) light microscopy-based study of nano- and microplanktonic protist communities of Adventfjorden waters in 2013. In general, protist dynamics corresponded to the classic paradigm for the Arctic ice-free waters with extremely low abundance and diversity ...
Isolation and characterization of antimicrobial peptides with unusual disulfide connectivity from the colonial ascidian Synoicum turgens
(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-12)
This study reports the isolation of two novel cysteine-rich antibacterial peptides, turgencin A and turgencin B, along with their oxidized derivatives, from the Arctic marine colonial ascidian <i>Synoicum turgens</i>. The peptides are post-translationally modified, containing six cysteines with an unusual disulfide connectivity of Cys<sup>1</sup>-Cys<sup>6</sup>, Cys<sup>2</sup>-Cys<sup>5</sup>, and ...
