Svært få funn av virus i tilbakevandrende laks selv om de samme virusene er vanlige i oppdrett Havforskningsinstituttet har undersøkt forekomsten av flere virus som er prevalent i oppdrett i tilbakevandrende laks fra ...

Salmon lice can impact the marine behaviour, growth, and survival of salmonids, but little is known about their effects on Arctic char. We present behavioural responses from the first dose-response experiment with wild ...

Coastal aquaculture is a globally expanding enterprise. Currently, 1200 salmon farms operate in coastal Norway, yet their capacity to aggregate and subsequently modify wild fish distributions is poorly known. Aggregations ...

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 ...

Salmon lice are external parasites on salmonids in the marine environment. During recent years, sea lice abundance has been increased due to the presence of salmon farming using on-growing floating seas-cages. Amongst ...

Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, ...

I 2007 ble 29 nasjonale laksefjorder opprettet. Disse er ment å gi et utvalg av de viktigste laksebestandene i Norge en særlig beskyttelse, inkludert mot oppdrettsvirksomhet i nærliggende fjord og kystområder. En statistisk ...

The culture of certain fish species to sizes at which they can reproduce has led to the escape of fertilised eggs or ‘escape through spawning’. To investigate the extent and ecological importance of spawning in sea-cages ...
