Selv om fiskeri- og havbruksnæringene er anerkjent som viktige bidragsytere til den globale produksjonen av sjømat, er de imidlertid også kjent for å ha større HMS-utfordringer og jobbrelaterte skader enn andre industrisegmenter. En økning av automasjonsnivået i gj...

Measurements were performed inside and in the wake of a commercial salmon sea cage. The key instrumentation included the following: sea bottom-mounted acoustic Doppler current profilers providing continuous concurrent flow velocity and turbulence information about the water columns; vessel-mounted a...

The CageReporter project adapts the use of autonomous and tetherless underwater vehicles as a carrier of sensor systems for data acquisition, where the data are transferred from sea-based fish cages to a centralized land base (Figure 1). The vehicle will use active motion con-trol and acquire data f...

This report presents results obtained in the CageReporter project regarding the development of a low cost hydroacoustic subsea communication system adapted for use in fish cages. The report mainly addresses tasks regarding the optimization of sender and receiver technology, as well as algorithms for...

Fisheries and fish farming are important global contributors to the production of seafood for human consumption. These industries are also known for substantially higher HSE risks and work-related injury frequencies which implies that increasing the automation level of high-risk operations within fi...

This paper presents a comparative study of mechanical properties of biodegradable PBSAT (polybutylene succinate co-adipate-co-terephthalate) and conventional polyamide (PA) gillnets used in Norwegian fisheries. Field tests were performed to simulate abandoned, lost, or otherwise discarded fishing ge...

Research within marine aquaculture has either focused on technology (e.g. farming structures, autonomous systems, harvesting and transport technologies) or biology (e.g. biomass control, feeding process, fish behavior and welfare). Here, we present a computational framework allowing the integrated a...

To avoid the negative impacts caused by biofouling development, aquaculture nets around the world are periodically cleaned using high-pressure washers. Net cleaning is labour-intense and costly, can damage antifouling coatings on the nets, and pose contamination as well as fish health and welfare ri...
