Salmon Smolt Production - Welfare Standards

Welfare considerations in Atlantic salmon smolt production, including freshwater rearing conditions and smoltification management.

Key Facts

Atlantic salmon undergo smoltification - a physiological transformation enabling salt water tolerance - once in life
Photoperiod manipulation using artificial lighting controls smoltification timing in hatcheries
Crowding during smolt grading and transfer causes acute stress with lasting effects on sea cage performance
RAS-reared smolts are increasingly replacing sea cage smolt production with controlled condition advantages
Welfare standards for smolt production are less developed than for sea cage growing phase in most certifications
