Effects on individual level behaviour in mackerel (Scomber scombrus) of sub-lethal capture related stressors: Crowding and hypoxia
(Peer reviewed; Journal article, 2019-03-13)Stress to fish during harvest in wild capture fisheries is known to negatively influence subsequent survival in catches that are released. Therefore, if fisheries are to be conducted sustainably, there is a need to promote ... -
Effects on schooling function in mackerel of sub-lethal capture related stressors: Crowding and hypoxia
(Peer reviewed; Journal article, 2017-12-28)The selectivity of fishing gears with respect to fish species and size is important, both for fisheries management and fishing operations. Purse seining is an efficient, environmentally friendly fish capture methodology ... -
Effekt av ferskvassbehandling på gjeller hjå laks (Salmo salar L.) med amøbegjellesjukdom (AGD): gjellepatologi, prevalens og tettleik av Paramoeba perurans
(Master thesis, 2020-06-23)Eit av dei største problema ein opplever i sjøfasen hjå oppdrettslaks er dårleg gjellehelse. Det har eit komplekst årsakstilhøve og er ofte assosiert med eit breitt spekter av patogen. Eit av patogena som kan infisere ... -
Effekt av ulike immuniseringsregimer mot pankreassykdom (PD) hos Atlantisk laks (Salmo salar L.), og betydningen av lakselus (Lepeophtheirus salmonis Krøyer) som stressfaktor ved immunisering.
(Master thesis, 2016-05-31)Den kommersielle vaksinestrategien som hittil har vært brukt i Norge for å bekjempe pankreassykdom (PD) har ikke hatt optimal effekt, ettersom en fremdeles opplever sykdom og dødelighet, til tross for vaksinasjon. Det er ... -
Effekt og omfang av 9.7- og 8.2- kuldeeventene ved Store Finnsjøen på Dovrefjell
(Master thesis, 2016-12-20)Her presenteres en pollenanalytisk detaljundersøkelse av det Holocene furu-maksimum i sedimenter fra Store Finnsjøen (1260 moh.) på Dovre. Furuskogen etablerte seg i Skandesfjellene fra ca. 10.3 ka BP og dominerte mellom ... -
Efficacy of early diagnosis and treatment in women with a family history of breast cancer
(Peer reviewed; Journal article, 1999)BACKGROUND: Surveillance programmes for women at increased genetic risk of breast cancer are being established worldwide but little is known of their efficacy in early detection of cancers and hence reduction in mortality. ... -
Efficiency and catch dynamics of collapsible square and conical crab pots used in the red king crab (Paralithodes camtschaticus) fishery
(Peer reviewed; Journal article, 2008)We compared the capture efficiency and catch dynamics of collapsible square and conical pots used in resource assessment and harvesting of red king crabs (Paralithodes camtschaticus [Tilesius, 1815]) in the Barents Sea. ... -
Egg buoyancy variability in local populations of Atlantic cod (Gadus morhua)
(Peer reviewed; Journal article, 2012)Previous studies have found strong evidences for Atlantic cod (Gadus morhua) egg retention in fjords, which are caused by the combination of vertical salinity structure, estuarine circulation, and egg specific gravity, ... -
Egg size and density estimates for three gadoids in Icelandic waters and their implications for the vertical distribution of eggs along a stratified water column
(Journal article; Peer reviewed, 2020)The vertical distribution of fish eggs can have important consequences for recruitment through its influence on dispersal trajectories and thus connectivity between spawning and nursery locations. Egg density and size are ... -
Eight decades of adaptive changes in herring reproductive investment: the joint effect of environment and exploitation
(Journal article; Peer reviewed, 2021)Reproductive investment is a central trait for population dynamics and productivity. Fishing and environmental variations are major drivers affecting population structure, dynamics, and adaptation of life-history and ... -
Eight Recommendations to Promote Effective Study Habits for Biology Students Enrolled in Online Courses
(Journal article; Peer reviewed, 2022)To achieve meaningful learning experiences in online classrooms, students must become self-regulated learners through the development of effective study habits. Currently, there is no set of recommendations to promote study ... -
Eksperimentell eksponering av laksefiskyngel for salmonid alphavirus (SAV3) – Sammenligning av mottakelighet og konsekvens hos brunørret (Salmo trutta L.) og atlantisk laks (Salmo salar L.)
(Master thesis, 2018-12)Salmonid alfavirus (SAV) forårsaker pankreassyke (PD) hos laksefisk i oppdrett. PD er utbredt i Norge og var den mest rapporterte virussykdommen i 2017. Det er en bekymring at rømt oppdrettsfisk som er infisert med viruset ... -
Eksperimentell smitte av grønngylt, Symphodus melops, med V.tapetis - isolatene CECT 4600, LP2 og NRP45
(Master thesis, 2011-08-30)The use of wrasse (Labridae) as cleanerfish in salmonid aquaculture is the only method for removal of salmon lice that does not have any negative impact on the environment. The use of wild-caught wrasse has increased during ... -
Electrical Stunning of Edible Crabs
(Research report, 2013)In the project StunCrab, kindly supported by the Norwegian Research Council, SeaSide AS, Hitramat AS and Nofima has successfully developed and implemented electrical stunning of edible crab. The research has shown highest ... -
Elemental composition of illicia and otoliths and their potential application to age validation in white anglerfish (Lophius piscatorius linnaeus, 1758)
(Journal article; Peer reviewed, 2021)The incorporation of trace elements into the calcified structures of fish can vary seasonally. Interpretation of these seasonal signals can provide information about fish age. This approach offers great promise for objectively ... -
