Norwegian aquaculture management and non-point source pollution
Non-point source (NPS) pollution of the salmon lice parasite Lepeophtheirus salmonis from Norwegian fish farms poses environmental risk for Norway’s wild Atlantic salmon stocks. To mitigate wild smolt mortality caused by this NPS pollution, the so-called traffic light system (TLS) was implemented in 2017.
