Fishermen, fisheries managers and scientists met on 15 October 2026 at a conference hosted by the Department for Environment, Food & Rural Affairs (Defra) to discuss the recent increase in octopus numbers off the south-west coast of England and how regulators and the industry might respond, according to the department's 16 October 2026 press release.

Defra reported that total UK vessel octopus landings into UK ports have risen by nearly 1500% since 2021, from an annual average of around 220 tonnes to over 3,700 tonnes. It said some fishermen have gained a valuable new fishery, while others, particularly in shellfish fisheries, are concerned about effects on their businesses. Attendees said shellfish stocks have been decimated by octopus consumption and raised concerns about more boats fishing the same areas, causing tension and safety issues.

Scientists presented evidence on environmental drivers, stock dynamics, research priorities and possible management options; international experts discussed effects in Brittany and approaches in Spain and Australia. Defra Chief Scientific Advisor Anjali Goswami, National Federation of Fishermen's Organisations CEO Mike Cohen and MMO Head of Sustainable Fisheries Isobel Johnston each commented on the need for collaboration. Defra and the Marine Management Organisation said they would publish a summary of the discussions to feed into future decision-making.
