Octopuses are highly intelligent invertebrates whose sophisticated cognition and behavior raise urgent welfare questions as aquaculture interest grows.
Octopuses represent a unique case in animal welfare: an intelligent, sentient invertebrate whose welfare protections have historically lagged behind vertebrates. Research documents their capacity for learning, problem-solving, and possibly pain experience. As global interest in octopus aquaculture grows, welfare standards are urgently needed. Current proposed aquaculture methods raise serious welfare concerns including isolation, inappropriate environments, and inhumane slaughter. The UK, EU, and other jurisdictions have begun extending welfare protections to octopuses.
