The states that have banned octopus farming are California and Washington.
California and Washington are the only 2 states that have banned the practice of farming octopuses.
Californian signed the Oppose Cruelty to Octopuses or (OCTO) Act into law in September of 2024.
The state of California is the first state to prohibit both the farming of octopuses and the sale of farmed octopus meat.
Washing also enacted the nation's first prohibition on octopus aquaculture in 2024, which made it illegal to farm octopuses for human consumption.
And even several states, including, Oregon, North Carolina, New Jersey, Connecticut, New York, Massachusetts and Hawaii have also introduced their own similar bills on farming octopuses.
And there is also an active federal bill in Congress to ban the practice of octopus farming worldwide.
Octopus farming is increasingly banned in several jurisdictions because the octopuses, which are highly intelligent, sentient creatures are naturally solitary and suffer intensely in captivity.
Additionally, farming of octopuses is ecologically unsustainable, as they are carnivores that require massive amounts of wild-caught fish for feed, which further depletes ocean ecosystems.
Octopuses have complex mental abilities, use tools, and solve problems.
Because octopuses are solitary, highly active, and territorial in the wild, confining them to crowded, sterile tanks causes severe stress, aggression, cannibalism, and high mortality rates.
To produce just one pound of farmed octopus, about three pounds of other marine animals are required as feed.
This makes the industry a net consumer of seafood, driving overfishing rather than alleviating it.
Intensive farming of octopuses also generates concentrated waste (feces, uneaten feed, and potential chemicals) that can spill into fragile coastal ecosystems, causing algal blooms and spreading diseases.
