An acoustic sensor transmitter for in situ assessment of water quality and fish behaviour during chemical treatment of a parasite-infected river system: tag design and practical use
Alfredsen, Knut; Urke, Henning Andre; Kristensen, Torstein; Kvakland, Marte; Grønningsæter, Åge; Hagen, Anders Gjørwad; Alfredsen, Jo Arve (Journal article; Peer reviewed, 2021) -
New concept for measuring swimming speed of free-ranging fish using acoustic telemetry and Doppler analysis
Hassan, Waseem; Føre, Martin; Urke, Henning Andre; Ulvund, John Birger; Bendiksen, Eskil; Alfredsen, Jo Arve (Peer reviewed; Journal article, 2022)A novel technique for measuring individual fish swimming speed based on conventional acoustic telemetry and Doppler analysis was tested with live tagged fish in a field experiment at a fish farm. The aim of the experiment ... -
A Persistent Sea-Going Platform for Robotic Fish Telemetry Using a Wave-Propelled USV: Technical Solution and Proof-of-Concept
Dallolio, Alberto; Bjerck, Helge Bostwick; Urke, Henning Andre; Alfredsen, Jo Arve (Peer reviewed; Journal article, 2022)Over the last few decades, acoustic fish telemetry has developed into a viable approach for remote monitoring of fish behaviour in the marine environment. Simultaneously, unmanned surface and underwater vehicles have found ... -
The risk of individual fish being captured multiple times in a catch and release fishery
Thorstad, Eva Bonsak; Diserud, Ola Håvard; Solem, Øyvind; Havn, Torgeir Børresen; Bjørum, Lars Rasmus Oftedal; Kristensen, Torstein; Urke, Henning Andre; Johansen, Martin Rognli; Lennox, Robert J.; Fiske, Peder; Uglem, Ingebrigt (Peer reviewed; Journal article, 2019)The proportion of angled Atlantic salmon Salmo salar L. being caught and released has increased. If individuals are repeatedly captured, this may have fish welfare consequences. Of 995 Atlantic salmon tagged during catch ... -
Synchrony and multimodality in the timing of Atlantic salmon smolt migration in two Norwegian fjords
Bjerck, Helge Bostwick; Urke, Henning Andre; Haugen, Thrond Oddvar; Alfredsen, Jo Arve; Ulvund, John Birger; Kristensen, Torstein (Peer reviewed; Journal article, 2021)The timing of the smolt migration of Atlantic salmon (Salmo salar) is a phenological trait increasingly important to the fitness of this species. Understanding when and how smolts migrate to the sea is crucial to understanding ... -
System for Real-Time Positioning and Monitoring of Fish in Commercial Marine Farms Based on Acoustic Telemetry and Internet of Fish (IoF)
Hassan, Waseem; Føre, Martin; Urke, Henning Andre; Kristensen, Torstein; Ulvund, John Birger; Alfredsen, Jo Arve (Chapter, 2019)In this study the performance of the Internet of Fish (IoF) concept, a real-time acoustic positioning and fish monitoring system, was assessed in a commercial marine fish farm in Norway. Central to the IoF concept is the ...
