(Journal article; Peer reviewed, 2013-10-15)The diet composition and prey selection of sprat (Sprattus sprattus) was studied in the Hardangerfjord, western Norway during four cruises in spring and autumn of 2009 and 2010. Feeding activity, indicated by stomach ... -
Differential changes in growth patterns of anadromous brown trout and Atlantic salmon from the River Etneelva over a 25-year period
(Journal article; Peer reviewed, 2013-10-15)Freshwater and marine growth of anadromous brown trout (Salmo trutta) and Atlantic salmon (Salmo salar) from the River Etneelva was analysed in relation to river, fjord and ocean temperatures during the periods 1976-1982 ... -
Disease interaction and pathogens exchange between wild and farmed fish populations with special reference to Norway
(Journal article; Peer reviewed, 2011-05-21)Norway has the largest salmon-farming industry in the world, an industry that is still growing, and in recent years production of marine species like Atlantic cod has also increased. At the same time, Norway has the world's ... -
Diseases of farmed Atlantic salmon Salmo salar associated with infections by the microsporidian Paranucleospora theridion
(Journal article; Peer reviewed, 2011-03-16)The microsporidian Paranucleospora theridion was discovered in Atlantic salmon Salmo salar suffering from proliferative gill disease in a marine farm in western Norway in 2008. The parasite develops in cells of the ... -
