Mystery as US salmon are found in Irish waters
A species of salmon more commonly associated with the west coast of North America has been found in rivers in the west of Ireland.
Inland Fisheries Ireland voiced its concern about the discovery of the pink salmon - which are of Pacific origin but have been found in rivers in counties Galway, Mayo and Donegal - in terms of what impact the fish may have on Ireland's Atlantic species.
The pink salmon, also known as humpback salmon, was also found earlier this month in Scotland.
A potentially invasive species to the UK, it may be related to fish introduced to the Barents Sea in Russia in the 1950s.
However, Dr Greg Forde, head of operations at Inland Fisheries Ireland, said: "It seems unlikely that these fish made a migration due to their small size." He added that the appearance of the species was a "mystery" and has urged the angling community to report any catch of pink salmon to Inland Fisheries Ireland.
