Farmed fish suffer pain and stress, says report that criticises welfare failings

Instead of Atlantic salmon and trout, study says the industry should focus on cultivating species with less complex needs

Those who care about the welfare of fish and seafood should opt for clams, mussels or seaweed, according to a new report, which says popular fish, including farmed Atlantic salmon and trout, have more complex welfare needs and are more likely to experience pain and suffering.

There is no scientific evidence of the behavioural and environmental needs of nearly 80% of aquatic species, an analysis of more than 400 species farmed around the world found.
