Biomonitoring using tagged sentinel fish and acoustic telemetry in commercial salmon aquaculture: A feasibility study
(Journal article; Peer reviewed, 2017-08)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, 2019-11)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 ... -
Drag Forces and deformation of aquaculture cages – full-scale towing tests in the field
(Journal article; Peer reviewed, 2018-02-23)Fish cages can experience strong loads due to hydrodynamic forces in the sea. Numerical models are often used to estimate drag forces on net cages, and the development and validation of such models is mostly based on ... -
Experimental evaluation of hydroacoustic instruments for ROV navigation along aquaculture net pens
(Journal article; Peer reviewed, 2016-09)An ultra-short baseline (USBL) system and a Doppler Velocity Log (DVL) system, both commonly applied for navigation and guidance of underwater vehicles, were tested with respect to their capabilities to support aquaculture ... -
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, 2016-05-10)tSpatial and temporal feed distribution in sea cages are important factors for the farmer, fish and envi-ronment due to the strong relation to growth, feed loss, pollution and welfare. This study presents a setof experimentally ... -
Measurement and simulation of the three-dimensional flow pattern and particle removal efficiencies in a large floating closed sea cage with multiple inlets and drains
(Journal article; Peer reviewed, 2018-01)This study investigated the three-dimensional flow structures in an ellipsoid, closed sea fish cage. The results are presented using computational fluid dynamics (CFD) simulations and experimental measurements. Experimental ... -
Modelling and simulation of rotary feed spreaders with application to sea cage aquaculture ? A study of common and alternative designs
(Journal article; Peer reviewed, 2018-08)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 ... -
Prediction of size-dependent risk of salmon smolt (Salmo salar) escape through fish farm nets
(Journal article; Peer reviewed, 2020-05)The escape of small smolt through farm cage netting is a major challenge faced by the Norwegian salmon farming industry. Escape can occur when the smolt placed in the cages are smaller than the size estimated by the farmers. ... -

Risk assessments in the Norwegian aquaculture industry: Status and improved practice
(Journal article; Peer reviewed, 2018-11)The Norwegian aquaculture industry has the potential to become the country’s leading ocean industry in the future. More than 99% of the produced biomass is Atlantic salmon and trout. Norwegian fish farming is characterised ...
