Octopus explosion off South West prompts talks between fishermen and scientists
Fishermen, scientists and regulators met to assess a dramatic rise in octopus catches off England’s south-west coast and agree coordinated responses to ecological and industry impacts.
A Defra-hosted conference brought together fishermen, scientists and fisheries managers to review evidence of a sharp increase in octopus landings off the south-west coast of England. Participants shared observations from the water and discussed how to respond to the sudden bloom, which has created both new fishing opportunities and concerns for shellfish fisheries.
Since 2021, UK octopus landings have risen from around 220 tonnes to over 3,700 tonnes, prompting calls for coordinated management. The conference aimed to pool practical experience and scientific findings to inform future decisions by Defra and the Marine Management Organisation.
Fishermen reported severe impacts on shellfish stocks and raised safety issues linked to increased vessel activity in shared fishing grounds. Scientists outlined environmental drivers behind the bloom and outlined research priorities and potential management measures for the emerging octopus fishery.
International experts described similar challenges in Brittany, Spain and Australia, offering lessons for UK regulators. Defra and the MMO will publish a summary of the discussions to guide upcoming policy decisions on managing the octopus bloom and its effects on coastal fisheries.
