“We will take appropriate action and look into any further reports, in particular whether they break relevant fisheries regulations.” French and British fishermen clash over scallop fishingCredit:Matthew Fearn “Neither Defra (the Department for Food and Rural Affairs) or the Maritime Management Organisation have helped us,” he added.“As fishermen, we have had to go to the French on a fisherman to fisherman basis to sort this out.”The CFPO called a meeting, which it said had had a positive outcome.“They claimed there had been a breakdown in communications and this was the work of one or two rogue skippers,” Mr Trebilcock said.“We agreed a working understanding for going forward and they have vowed to ensure it doesn’t happen again. We have a follow-up meeting in three months.”A Defra spokesperson said: “We are very concerned to hear about these incidents. The Marine Management Organisation has been in discussion with fishermen in Cornwall about the reports of damage.”They have looked into these and have passed information to other relevant authorities. We have a robust enforcement system in place. “These are small businesses losing hundreds of thousands of pounds – it’s significant and has been going on for several months. It was getting ridiculous, there was a lot of anger and we knew it could not carry on.”He said the government’s unwillingness to get involved had been “disappointing.” The tensions have come to light just days after British and French fishermen reached a deal to end the so-called scallop wars in the Channel.Earlier this month, around 40 French vessels fired flares, hurled stones and rammed a small group of British trawlers fishing legally in waters off northern France.French fishermen are banned from catching scallops between May 15 and Oct 1 to conserve stocks, but British boats are not subject to the ban.From Tuesday, larger British boats withdrew from the disputed area off the Normandy coast for six weeks. UK-based boats under 15m long will still be able to fish in the Bay of Seine, where the row broke out in August. Want the best of The Telegraph direct to your email and WhatsApp?

British fishermen came under fire during a dispute over scallop bedsCredit:FRED TANNEAU/AFP/Getty Images “Much of these problems pre-date the scallop wars but the tensions could all be rooted in the same thing and it is unlikely to have helped,” he said.“We tell the French the areas where the crab pots are and they usually ignore it but they have been claiming, incredibly, that they did not know where the gear was. The scallop wars are barely over but already new tensions have emerged in the English Channel in the form of crab wars.Cornish fishermen have accused French trawlers of deliberately sabotaging their crab pots, costing them hundreds of thousands of pounds.They said French trawlers had been seen in English waters towing nets “without a care in the world” within the UK’s 12-mile limit.Paul Trebilcock, chief executive of the Cornish Fish Producers Organisation (CFPO), said: “They are just dragging through all the gear, they break the ropes, damage the pots or just tow them away altogether.”In the absence of what they claimed was a lack of action from Government agencies, the CFPO took matters into their own hands on Thursday, thrashing the matter out with French fishermen at a face-to-face meeting in Plymouth.Mr Trebilcock admitted that the damage, caused by a dozen or so boats from Brittany, could be Brexit-related or have some link with the frustrations caused by scallop wars.
