Squid and Cuttlefish Welfare in Fisheries and Research

Squid and cuttlefish are intelligent cephalopods caught in large quantities globally. Their cognitive sophistication makes their welfare in fisheries and research settings an important ethical question.

Key Facts

Cuttlefish have demonstrated spatial working memory, episodic-like memory, and self-control in research studies
Squid are caught globally by jigging, trawling, and purse seine in enormous quantities
Global squid catch exceeds 4 million tonnes annually
Cuttlefish can change colour patterns in milliseconds using up to 10 million chromatophores
Both squid and cuttlefish are included in EU research animal protections
They are killed primarily by asphyxiation or freezing without prior stunning in commercial fisheries

Welfare Considerations

Cuttlefish research has produced some of the most compelling evidence for cephalopod cognition — including a delayed gratification task showing they can sacrifice immediate rewards for larger future ones, analogous to human marshmallow tests. This cognitive sophistication makes their welfare in any context highly significant. Squid jigging — a fishing method using multiple barbed hooks — causes tissue trauma to caught squid. Commercial squid processing often involves live animals being processed without stunning. Squid caught in large-scale purse seines are compressed with the same crowding stress as other schooling fish. The EU recognition of cephalopod sentience in research settings has not extended to food production.
