Commercial octopus farming is being developed by several companies — but the cognitive complexity of octopuses raises profound welfare questions that must be addressed before scaling.
The pending commercialization of octopus farming raises some of the most significant welfare concerns in aquaculture because of the cognitive complexity of the animals involved. Octopuses are intelligent, curious, and highly individual — each develops distinct behavioral patterns and preferences. They are also deeply asocial — forcing octopuses into proximity with conspecifics creates chronic stress and aggression. The farming models under development have no precedent for managing sentient, territorial, individually different animals at commercial scale in ways that meet their welfare needs. Before octopus farming scales, the industry must develop and adopt species-specific welfare standards that address social conflict, environmental complexity, slaughter methods, and minimum space requirements.
