Latest offender fined £5,000
Environment, Food and Agriculture Minister Richard Ronan says his department is sending out a strong message about illegal fishing.
It comes after an Irish trawlerman was fined £5,000 for fishing king scallops in a closed area off the Island's west coast.
The authorities were alerted thanks to a satellite tracker fitted to the man's boat.
Mr Ronan says those who stray off limits will be caught.
