Aquaculture Arctic Char Welfare | Animal Welfare Hub

Arctic char is a premium cold-water farmed species with specific welfare requirements for temperature, stocking density, and feed management.

Key Facts

Arctic char is farmed primarily in Iceland, Norway, Canada, and Ireland in cold freshwater systems.
They are salmonids closely related to trout, with a preferred temperature range of 8-12 degrees Celsius.
Arctic char are more sensitive to crowding and poor water quality than Atlantic salmon.
Their high market value incentivises careful management, which generally correlates with better welfare outcomes.
Recirculating aquaculture systems (RAS) are increasingly used to provide stable temperature and water quality.

Welfare Considerations

Arctic char welfare in aquaculture depends critically on temperature management — above 15 degrees Celsius they experience heat stress, reduced feed intake, and increased disease susceptibility. Stocking density management is essential; crowded conditions lead to aggression, fin damage, and chronic stress. The sensitivity of Arctic char to environmental disturbance makes good stockmanship — daily observation and prompt response to behavioural changes — particularly important. Slaughter welfare for salmonids including Arctic char requires pre-slaughter stunning; percussive or electrical stunning before killing is best practice and increasingly mandated by certification schemes.

What You Can Do

Choose Arctic char from certified producers committed to water quality and stocking density standards.
Support welfare certification schemes for salmonid aquaculture that include Arctic char.
Advocate for mandatory pre-slaughter stunning requirements for all farmed salmonids.
Appreciate Arctic char as an alternative to Atlantic salmon with potentially better welfare credentials when managed well.
