Effect of ultrasonic cavitation on small and large organisms for water disinfection during fish transport
Motivated by the need for additional tools to disinfect discharge water from well boats, and to prevent distribution of salmon lice, the effect of ultrasonic cavitation on the planktonic stages of the salmon louse, nauplii and copepodids, as well as marine heterotrophic bacteria, and the marine gree...
Experimental study of installation procedure and volume estimation of tarpaulin for chemical treatment of fish in floating cages
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 to calculate the correct dose of the agent the volume of the enclosed water i...
FLEXIBLE TARPAULIN BAGS FOR SAFEKEEPING OF REVERSE OSMOSIS (RO) PRODUCED FRESHWATER FOR USE IN AGD AND SEA LICE TREATMENT.

Modelling growth performance and feeding behaviour of Atlantic salmon (Salmo salar L.) in commercial-size aquaculture net pens: Model details and validation through full-scale experiments
We have developed a mathematical modelwhich estimates the growth performance of Atlantic salmon in aquaculture production units. The model consists of sub-models estimating the behaviour and energetics of the fish, the distribution of feed pellets, and the abiotic conditions in the water column. A f...
Three-dimensional deformation of a large circular flexible sea cage in high currents: Field experiment and modeling
This paper presents the full-scale measurements of the deformation and current reduction of a large-scale fish sea cage submitted to high currents. Pressure tags were used to measure the cage deformation and the vertical displacement of the bottom ring, while an Acoustic Doppler Current Profiler (AD...
Changes to flow and turbulence caused by different concentrations of fish in a circular tank
The effects of juvenile Atlantic salmon (Salmo salar) on flow and turbulence in a circular tank were investigated. Three fish sizes were studied (37.5 g, 82.5 g and 218 g) with between 268,050 and 318,000 fish in a 15 m diameter by 4 m deep tank (mean stocking densities of 15.3 kg m–3, 35.6 kg m–3, ...
