Cephalopods are the most cognitively complex invertebrates; their welfare in fishing, research, and aquaculture contexts deserves serious consideration.
Cephalopods caught by jigging are rapidly pulled from depth, causing barotrauma and internal injuries before death. Research cephalopods experience experimental procedures without consistent welfare oversight. Octopuses and cuttlefish in laboratory settings may be kept in conditions that prevent expression of their complex behavioral repertoire. The legal recognition of cephalopod sentience in UK law requires translation into operational welfare standards for research and commercial use.
