Behavioural response of farmed Atlantic salmon (Salmo salar L.) to artificial underwater lights: Wavelet analysis of acoustic telemetry data
(Peer reviewed; Journal article, 2021)Biological, environmental, economic and ethical issues become increasingly pertinent as the scale of the aquaculture industry expands. This study used acoustic telemetry data and wavelet analysis to investigate behavioural ... -
Biomonitoring using tagged sentinel fish and acoustic telemetry in commercial salmon aquaculture: A feasibility study
(Journal article; Peer reviewed, 2017)We tested if it is technically feasible to monitor fish in real-time in full-scale commercial fish farms using acoustic telemetry. 31 Atlantic salmon were equipped with acoustic transmitter tags containing depth sensors. ... -
Determining spatial feed distribution in sea cage aquaculture using an aerial camera platform
(Journal article; Peer reviewed, 2019)Within this paper we describe an unmanned aerial vehicle (UAV) based method to estimate the spatial feed pellet distribution in salmon fish-cages and exploit it within a case study to determine the radial pellet distribution ... -
Experimental study of installation procedure and volume estimation of tarpaulin for chemical treatment of fish in floating cages
(Journal article; Peer reviewed, 2017)In the salmon industry chemical delousing is done by enclosing the cage in a tarpaulin, and then mixing the chemical agent in the enclosed water volume. Correct dosage is important to obtain the wanted effect, and in order ... -
Intrinsic settling rate and spatial diffusion properties of extruded fish feed pellets
(Journal article; Peer reviewed, 2016)Spatial and temporal feed distribution in sea cages are important factors for the farmer, fish and environment due to the strong relation to growth, feed loss, pollution and welfare. This study presents a set of experimentally ... -
Modelling and simulation of rotary feed spreaders with application to sea cage aquaculture – A study of common and alternative designs
(Journal article; Peer reviewed, 2018)Rotary feed spreaders are extensively used in large scale fish aquaculture and are tasked with distributing pelletized feed in a spatially uniform manner over the water surface. Questions have been raised with respect to ...
