New report: salmon farms and sea trout in Norway

A new report from Norway’s Scientific Advisory Committee for Atlantic Salmon, assessing human impacts on sea trout, concludes that:

Salmon lice from aquaculture farms is by far the largest threat to sea trout… To improve the situation, the salmon lice infestation pressure from fish farms must be considerably reduced’.

The report places the threat from sea lice ahead of climate change, culverts, channelisation, habitat loss, agriculture, hydropower, water abstraction, infectious diseases and invasive non-native species, in terms of negative impacts on Norwegian sea trout populations.
