AN ALERT HAS been issued asking anglers and the public to report any sightings of Pacific pink salmon amid fears that the invasive species could pose a threat to native salmon and trout.
Inland Fisheries Ireland has warned that “aggressive” Pacific pink salmon could force Atlantic salmon and trout out of holding pools into smaller channels.
The state agency, which is responsible for the protection and conservation of freshwater fish and habitats, is concerned that, if there are large numbers of the non-native species in Irish rivers, it may have negative impacts on Ireland’s salmon and trout populations in the future.
Also known as ‘humpback’ salmon, pink salmon were very rare in Irish waters until 2017 and are believed to have originated from stocking programmes in Russia.
“If Pacific pink salmon become established in Irish rivers, they will be competing with Irish salmon and trout for food and space,” Dr Paddy Gargan of Inland Fisheries Ireland said.
Pink salmon also display aggressive behaviour towards native fish and a large invasion of pink salmon could push out Atlantic salmon and trout from holding pools into smaller channels.
The first reported catch of a Pacific pink salmon in Ireland this year came in the Ridge Pool at Moy Fishery in Co Mayo on 27 June.
Anglers across the country are also being asked to report any further catches of Pacific pink salmon to Inland Fisheries Ireland and to assist with research efforts by following these steps:
