Salmon louse infestation levels on sea trout can be predicted from a hydrodynamic lice dispersal model

Journal of Applied Ecology, Volume 59, Issue 3, Page 704-714, March 2022., 2022
Wild sea trout, spending its entire feeding migration in fjords and coastal areas, is at higher risk than wild Atlantic salmon to lice infestations from industrial salmon farming. The high levels of lice infestation we observed on sea trout question the environmental sustainability of the current aquaculture industry in areas with intensive farming. We

Timing is everything: Survival of Atlantic salmon Salmo salar postsmolts during events of high salmon lice densities

Journal of Applied Ecology, Volume 57, Issue 6, Page 1149-1160, June 2020., 2020
We document that high lice density can cause more than 50 times higher mortality risk in Atlantic salmon on their sea migration, even in a fjord with protected status. Fine‐tuned and hard‐to‐predict year‐to‐year differences in timing, both for the wild smolt migration and the population build‐up of lice released from aquaculture, means life or death to
