Salmon Scotland and the Government have ten categories for the causes of mortality, following the Farmed Fish Health Framework. None of these is specifically for the fish killed by treatments administered by farmers, so treatment deaths are lumped with those caused by various diseases and sea lice, making it impossible to know how many fish die 2 due to treatments, the most important non-infectious killer of farmed fish, according to Mowi. • Cleaner fish mortality seems to be excluded.
