Fishermen, fisheries managers, and scientists convened yesterday, 15 October, for a Defra-hosted conference to address a recent surge in octopus numbers off the south-west coast of England. Since 2021, total UK vessel octopus landings into UK ports have increased by nearly 1500%, rising from an annual average of around 220 tonnes to over 3,700 tonnes.
This dramatic increase has created a valuable new fishery for some, while others, particularly those in shellfish fisheries, have expressed serious concerns about the impact on their businesses. Fishermen reported that shellfish stocks have been decimated by octopus consumption and raised issues regarding increased boat traffic and safety.
Scientists presented evidence on environmental factors driving the bloom, octopus stock dynamics, and potential management options. International experts also shared insights from Brittany, Spain, and Australia regarding similar situations. Defra and the Marine Management Organisation (MMO) will publish a summary of the discussions to inform future decision-making.
