Proposals for commercial octopus farming have sparked welfare debate given octopus intelligence, solitary nature, and the lack of humane slaughter methods.
Octopuses show behavioral indicators of pain, fear, and stress. Their solitary nature means high-density confinement creates conditions of chronic social stress that cannot be mitigated by enrichment. The combination of high cognitive capacity, solitary biology, and lack of humane slaughter methods makes farming particularly problematic.
