Inland Fisheries Ireland has received reports that individual fresh-run wild salmon have been encountered in the River Corrib, Co. Galway displaying suspected signs of red skin disease (RSD).
In the past few weeks, suspected cases have been reported in small numbers of returning salmon in Denmark, Norway and Scotland.
Salmon affected by RSD have a characteristic red-spotted rash on their underbelly and may appear lethargic or moribund.
The rash can either be localised or extend along some or most the length of the fish.
Within the operational constraints imposed by the COVID-19 National Public Health Emergency, IFI staff are continuing to liaise with the Fish Health Unit in the Marine Institute and international colleagues to monitor and respond to the situation.
As part of this, where practicable, anglers and fishery owners are asked to report any incidences of salmon with signs of RSD to IFI to help determine the occurrence of the disease nationally.
Anglers who capture such salmon are advised to follow normal biosecurity procedures and disinfect tackle, waders and equipment.
Until the cause of the disease has been determined and the risk of spreading the disease established, affected salmon should not be removed from the water.
