Over 100 boats were reportedly seen in protected fishing areas over the past four years, and campaigners say rogue fishermen are supplying a black market for seafood.
Video footage of damage to the seabed by illegal scallop dredging off Jura has been obtained by The Ferret, prompting calls for urgent enforcement action to be taken against rogue fisherman.
The skipper of a scallop dredger registered in Scotland has been fined £1,000 after being caught fishing in territorial waters off Guernsey.
Suspicious scallop dredging activity has taken place in the Sound of Mull, according to the campaign group, Open Seas.
Underwater film footage revealing the damage allegedly caused by illegal scallop dredging is being published by The Ferret in the wake of claims that protected wildlife areas are being “pulverised”.
