Fishermen, scientists and fisheries managers have met to discuss a sharp increase in octopus numbers off south west England, amid concerns about shellfish stocks and opportunities for a new fishery. Defra hosted the conference on 15 October, bringing together industry representatives, regulators and international experts. According to the department, octopus landed by UK vessels at UK ports has risen from an annual average of around 220 tonnes to more than 3,700 tonnes since 2021.
Fishing representatives reported substantial losses of shellfish to octopus predation, alongside tensions and safety concerns as more boats operate in the same areas. Scientists discussed environmental factors behind the increase, research priorities and possible management measures. Experts also shared experience from Brittany, Spain and Australia.
Defra and the Marine Management Organisation will publish a summary to inform future decisions. Mike Cohen, chief executive of the National Federation of Fishermen’s Organisations, said the industry had proposed the conference and described the developing fishery as presenting both threats and opportunities.
