To obtain more knowledge of current induced drag forces on sugar kelp, towing tests with ropes containing cultivated sugar kelp was conducted. As freshwater may damage the kelp and cause changes in its mechanical response, tests were performed in a test facility containing seawater. A special purpo...

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 laboratory tests that can be performed under controlled conditions. However, severa...

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...

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...

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...

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...
