I recently visited the fishing industry in Plymouth and was made aware of reports of an unusual abundance of octopus in the Southwest including Cornwall.

Defra understands this ‘octopus bloom’ is impacting shellfish potting fisheries and causing concern to the fishing industry in the Southwest.

Government scientists, the Marine Management Organisation and local Inshore Fisheries Conservation Authorities have met with Defra on the 20th of May to discuss this phenomenon, the evidence, the impacts on the crab and lobster stocks as well as possible actions.
