Four men have been convicted for separate illegal salmon angling offences in County Sligo.
Inland Fisheries Ireland has secured the convictions, with fines and costs of more than €6,000 levied.
In one case, a man snorkelled offshore to capture wild Atlantic salmon.
In another incident a man took a salmon from a catch-and-release river, and placed it into a rucksack before attempting to leave by bike.
In separate cases, two men were prosecuted for failing to produce a salmon licence or a permit to fish.
