The rapid growth in aquaculture means that billions of individual aquatic animals are now being farmed without basic information that could help ensure even minimal welfare standards. Our newly published study shows that these welfare risks are not uniform: Aquaculture is likely to have severe effects on welfare for some species, but negligible impacts on others.
Whenever humans manage animals on a large scale, welfare becomes a concern. As experts on aquatic animals and their welfare, we believe that taking proactive measures to shape the aquaculture industry’s growth will be critical for its long-term success.

In a wide-ranging review of the existing science, we identified seven risk factors in fish and other sea creatures that would be challenging or impractical to accommodate in captivity. They include 1) migratory behavior, 2) solitary social structures, 3) long life spans, 4) carnivorous feeding habits, 5) cannibalism, 6) living at depths of 165 feet (50 meters) or more, and 7) elaborate courtship or involved parental care.
