A total of 200 metres of salmon nets were recovered.
A Killybegs man was netted by Inland Fisheries Ireland officers snorkelling offshore in an attempt to land salmon.
Gerard McGuinness, of Largymore, Killybegs, was fined when he appeared at Sligo District Court.
McGuinness was observed swimming, in a wetsuit and snorkel gear, to a 100-metre net set offshore, in an attempt to capture wild Atlantic salmon.
The incident took place at Roskeeragh Point, Mullaghmore, County Sligo, in April, 2023.
Fisheries officers engaged with Mr McGuinness and a total of 200 metres of salmon nets were recovered.
He was fined €2,000, must pay €750 in costs to IFI, and his equipment was seized.
Mary Walsh, Director of IFI’s Western River Basin, Ballina said: “The protection of Ireland’s wild Atlantic salmon stocks is a crucial objective for Inland Fisheries Ireland to ensure these iconic fish survive and thrive.
“I commend our fisheries officers who were instrumental in protecting the State’s fisheries resources in these incidents.”
