Octopuses and squid have complex nervous systems and behavior that warrant serious welfare consideration, with farming proposals raising significant ethical questions.
Cephalopods challenge our categories of which animals deserve welfare consideration. Octopuses in particular show behavioral complexity, individual personalities, and problem-solving that suggest rich inner lives. The proposal to farm octopuses intensively conflicts with what we know about their welfare needs - they are solitary, territorial, and require environmental complexity. Leading welfare scientists have publicly opposed octopus farming on welfare grounds. The precautionary principle strongly supports caution.
