Automatisk posisjonering av akustisk merket smolt i tre dimensjoner – utprøving og evaluering i Mandalsvassdraget.
(NINA rapport;1072, Research report, 2014)Et nytt system som kan gi tredimensjonal (3D) posisjonering av smolt ved hjelp av trådløs akustisk telemetri ble utprøvd og evaluert i Mandalsvassdraget sommeren 2014. I forsøkene ble signaler fra akustiske merker logget ... -
Bioenergetic consequences of warming rivers to adult Atlantic salmon Salmo salar during their spawning migration
(Journal article; Peer reviewed, 2018)1. Climate change poses a challenge to wild fishes, yet little is known about the behavioural use and metabolic consequences of thermally heterogeneous water encountered by wild salmon during their energetically demanding ... -
Downstream migration of Atlantic salmon smolt at three German hydropower stations
(NINA Rapport;1203, Research report, 2016-10-04)Økland, F., Teichert, M.A.K., Thorstad, E.B., Havn, T.B., Heermann, L., Sæther, S.A., Diserud, O.H., Tambets, M., Hedger, R.D. & Borcherding, J. 2016. Downstream migration of Atlantic salmon smolt at three German hydropower ... -
European eel Anguilla anguilla compromise speed for safety in the early marine spawning migration
(Journal article; Peer reviewed, 2018)There are substantial benefits to potential fitness conferred to animals that undertake migrations. However, animals must make compromises to maximize survival and compensate for the risks associated with long-distance ... -
Migrating silver eels return from the sea to the river of origin after a false start
(Peer reviewed; Journal article, 2021)The European eel’s singular spawning migration from European waters towards the Sargasso Sea remains elusive, including the early phase of migration at sea. During spawning migration, the movement of freshwater resident ... -
Oppvandring og fordeling av laks i Osenvassdraget i Molde kommune: Resultater fra undersøkelser i 2014
(NINA Rapport;1184, Research report, 2015-07-01)Ulvan, E.M., Bremset, G., Aronsen, T., Thorstad, E.B., Solem, Ø., Økland, F., Havn, T. B. 2015. Oppvandring og fordeling av laks i Osenvassdraget i Molde kommune: Resultater fra undersøkelser i 2014. - NINA Rapport 1184. ... -
Positioning aquatic animals with acoustic transmitters
(Peer reviewed; Journal article, 2023)1. Geolocating aquatic animals with acoustic tags has been ongoing for decades, relying on the detection of acoustic signals at multiple receivers with known positions to calculate a 2D or 3D position, and ultimately ... -
Restoration of fish migration in the Danube River at Iron Gate Dams in Romania and Serbia. Studies of fish behaviour in 2019 and 2021
(NINA Rapport;2030, Research report, 2021)Paraschiv, M., Økland, F., Lenhardt, M., Paterson, R.A., Hont, S., Cvijanovic, G., Havn, T.B., Iani, M., Smederevac-Lalic, M., Nikčević, M., Neacșu, N., Nikolić, D. & Thorstad, E.B. 2021. Restoration of fish migration in ... -
Smoltutvandring forbi Laudal Kraftverk i Mandalselva i 2013
(NINA rapport;1067, Research report, 2014)Vellykket produksjon av laks og muligheter for fiske øverst i Mandalsvassdraget forutsetter at smolt fra øvre deler av elva kan vandre forbi Laudal kraftverk uskadd ut i sjøen. Kraftverket har inntak ved utløpet av Mannflåvann ... -
Temporal non-independence of foraging dive and surface duration sequences in the European shag Gulosus aristotelis
(Peer reviewed; Journal article, 2023)Studies of foraging behaviour and respiratory physiology in breath-holding divers often assume that each dive cycle (dive plus surface duration) is physiologically and ecologically independent within a series (or “bout”) ... -
The use of external electronic tags on fish: an evaluation of tag retention and tagging effects
(Peer reviewed; Journal article, 2015)External tagging of fish with electronic tags has been used for decades for a wide range of marine and freshwater species. In the early years of fish telemetry research, it was the most commonly used attachment method, ... -
Toward a decade of ocean science for sustainable development through acoustic animal tracking
(Peer reviewed; Journal article, 2022)The ocean is a key component of the Earth's dynamics, providing a great variety of ecosystem services to humans. Yet, human activities are globally changing its structure and major components, including marine biodiversity. ...
