Bacterial growth response to copepod grazing in aquatic ecosystems
(Peer reviewed; Journal article, 2007)The growth rate response of bacterial communities to the potential increase of dissolved organic matter (DOM) produced by the copepod Acartia tonsa was assessed in experiments conducted in three stations representing three ... -
Bacterial Response to Permafrost Derived Organic Matter Input in an Arctic Fjord
(Peer reviewed; Journal article, 2018-08-06)The warming of the Arctic causes increased riverine discharge, coastal erosion, and the thawing of permafrost. Together, this is leading to an increased wash out of terrestrial dissolved organic matter (tDOM) into the ... -
Bacteriophages targeting pathogenic bacteria isolated from lumpfish (Cyclopterus lumpus L.) and Atlantic salmon (Salmo salar L.)
(Master thesis, 2020-12-03)Bacterial diseases in aquaculture lead to reduced health and mortality of fish as well as economic consequences for the producer. Antibiotics are an important antimicrobial to control bacterial diseases, however, concerns ... -
Balanced harvest : concept, policies, evidence, and management implications
(Peer reviewed; Journal article, 2019-06-11)Balanced harvest has been proposed to reduce fishing impact on ecosystems while simultaneously maintaining or even increasing fishery yield. The concept has attracted broad interest, but also received criticisms. In this ... -
Balanced harvest: Utopia, failure, or a functional strategy?
(Peer reviewed; Journal article, 2016-04-21)Since “balanced harvest” was proposed in 2010 as a possible tool in the operationalization of the ecosystem approach to fisheries (EAF), the concept gained extensive international attention. Because maintaining ecosystem ... -
Ballan wrasse (Labrus bergylta) predation on hatchery reared scallop (Pecten maximus) spat
(Master thesis, 2005)Sea ranching of the great scallop (Pecten maximus) may have a high potential for future aquaculture in Norway. The edible crab (Cancer pagurus) and starfish (Asterias rubens) have been identified as the major predators, ... -
Barents Sea capelin and us; Do they really mature and migrate at 14cm? Or have we become prisoners in our own Platonic allegory? How shall we respond?
(Master thesis, 2018-06-15)Capelin (Mallotus Villosus) are an important component of the Barents Sea ecosystem. As zooplankton consumers they play a role in channelling energy up the food web, and they have the potential to represent a biomass of ... -
Bark beetles and pinhole borers (Curculionidae, Scolytinae, Platypodinae) alien to Europe
(Peer reviewed; Journal article, 2010-09-17)Invasive bark beetles are posing a major threat to forest resources around the world. DAISIE’s web-based and printed databases of invasive species in Europe provide an incomplete and misleading picture of the alien scolytines ... -
A baseline for the genetic stock identification of Atlantic herring, Clupea harengus, in ICES Divisions 6.a, 7.b-c
(Journal article; Peer reviewed, 2022)Atlantic herring in International Council for Exploration of the Sea (ICES) Divisions 6.a, 7.b–c comprises at least three populations, distinguished by temporal and spatial differences in spawning, which have until recently ... -
Basic mechanisms for control of appetite and feed intake in Atlantic salmon (Salmo salar)
(Doctoral thesis, 2022-11-10)Atlantisk laks (Salmo salar L.) er en nøkkelart i norsk sjømateksport, og representerer 70 – 80 Mrd NOK i verdi. Den store økningen i produksjon kombinert med overfôring har bidratt til negative effekter på det marine ... -
Bat (Chiroptera) activity and community composition in contrasting agricultural landscapes and the adjacent Budongo forest reserve, Uganda
(Master thesis, 2010-06-01)Abstract. Human activities are causing a biodiversity crisis in all biomes of the Earth. As the world's population continues to grow, more land will be converted to agricultural land to meet the growing food demands, ... -
A Battle Lost? Report on Two Centuries of Invasion and Management of Lantana camara L. in Australia, India and South Africa
(Peer reviewed; Journal article, 2012-03-05)Recent discussion on invasive species has invigorated the debate on strategies to manage these species. Lantana camara L., a shrub native to the American tropics, has become one of the worst weeds in recorded history. In ... -
Behavior-dependent selectivity of yellowtail flounder (Limanda ferruginea) in the mouth of a commercial bottom trawl
(Peer reviewed; Journal article, 2015-09-02)To improve the efficiency of a commercial bottom trawl for catching yellowtail flounder (Limanda ferruginea), we studied the behavior of individuals in the middle of the trawl mouth. Observations were conducted with a ... -
Behavioral responses of herring (Clupea harengus) to 1–2 and 6–7 kHz sonar signals and killer whale feeding sounds
(Peer reviewed; Journal article, 2009)Military antisubmarine sonars produce intense sounds within the hearing range of most clupeid fish. The behavioral reactions of overwintering herring Clupea harengus to sonar signals of two different frequency ranges 1–2 ... -

Behavioural and physiological adaptations of the bearded goby, a key fish species of the extreme environment of the northern Benguela upwelling
(Peer reviewed; Journal article, 2011-03-14)Nutrient-rich, upwelling marine areas with high productivity often produce sediments dominated by organic-rich mud. Here, intense decay processes create hypoxic conditions with high concentrations of hydrogen sulphide and ... -
Behavioural and welfare implications of a new slipping methodology for purse seine fisheries in Norwegian waters
(Peer reviewed; Journal article, 2019-03-11)The release of unwanted fish from purse seines whilst still in the water is termed slipping and may lead to significant mortality following release. The objective of this study was to determine the fish welfare implications ... -
