Cage size affects dissolved oxygen distribution in salmon aquaculture

Oldham, Tina; Oppedal, Frode; Dempster, Timothy David (Journal article; Peer reviewed, 2018)

Atlantic salmon aquaculture is shifting toward larger cages, but the water quality implications of this shift are unknown. While larger cages could improve profitability through economies of scale, they may increase the ...
Oxygen gradients affect behaviour of caged Atlantic salmon Salmo salar

Oldham, Tina; Dempster, Tim; Fosse, Jan Olav; Oppedal, Frode (Peer reviewed; Journal article, 2017)

Dissolved oxygen (DO) conditions in marine aquaculture cages are heterogeneous and fluctuate rapidly. Here, by temporarily wrapping a tarpaulin around the top 0 to 6 m of a marine cage (~2000 m3), we manipulated DO to ...
Surface environment modification in Atlantic salmon sea-cages: Effects on amoebic gill disease, salmon lice, growth and welfare

Wright, Daniel William; Geitung, Lena; Karlsbakk, Egil; Stien, Lars Helge; Dempster, Timothy David; Oldham, Tina; Nola, Velimir; Oppedal, Frode (Journal article; Peer reviewed, 2018)

Surface environment modification is a potential parasite control strategy in Atlantic salmon sea-cage farming. For instance, a temporary low salinity surface layer in commercial-scale snorkel sea-cages has coincided with ...
