A predator has been found in one of the most important trout and salmon spawning areas for Lough Corrib.

Trout anglers have discovered Pike in Loughs Boffin and Agraffard near Oughterard.

Pike are a predatory species which feed on young trout and salmon.

The Western Regional Fisheries Board is investigating their probable deliberate introduction and has described it as 'environmental vandalism'.

The Pike will threaten the wild salmon and trout population for Lough Corrib.

Western Regional Fisheries Board Inspector Kevin Crowley says it's a disaster which will affect the Corrib for years to come.
