Proposals to farm octopuses commercially raise serious welfare concerns given the strong evidence that octopuses are sentient and suffer in captivity.
Octopuses show clear signs of sentience including pain avoidance, learning, and emotional states. Intensive farming would deny them the individual territory, enrichment, and hunting behaviour they require. Stress in octopuses causes physiological damage and shortened lifespan. Slaughter methods suitable for octopuses have not been developed. Experts widely oppose octopus farming.
