Commercial octopus farming is being developed in several countries, raising profound welfare concerns about housing solitary predators at high density and supplying appropriate diets.
Octopus farming represents a frontier welfare challenge. These are cognitively sophisticated animals with complex behavioural needs that appear fundamentally incompatible with high-density commercial production. Individual housing at scale is economically questionable; group housing causes lethal aggression. Providing the enrichment, prey complexity, and space that octopuses require individually is likely to make commercial farming unviable at welfare-compatible standards. Many welfare scientists argue a moratorium is needed pending welfare framework development.
