The Environment Agency is urging anglers to report unusual catches after several pink salmon sightings in North-East waters.
Recently, a non-native pink salmon was caught in the River Tyne at Wylam, and around 100 are believed to have been caught in waters off the North-East and Yorkshire coast in recent months.
Further afield, anglers have confirmed catches in a number of rivers in Scotland and in western Ireland.
The Agency is collecting vital data about sightings so officers can monitor the situation to determine any impact on the local environment and species. Data collected will help people to understand how to manage the arrival of pink salmon in the UK.
Jonathan Shelley, from the Agency, said: “It is quite unusual to find pink salmon in our waters and we’re keen anglers know we’re aware of the sightings and we’re investigating.
“I’d urge anglers to contact us if they see any non-native salmon in the waters, with a date, location and, if possible, a photograph, which would really help us identify them and build up a picture of where they are.”
“We are monitoring the situation and early indications is that there is no major impact on wild fish stocks at this point in time.”
Anglers holding a salmon licence who catch pink salmon are asked not to return the fish to the water. Instead they are asked to dispatch them humanely and, if possible, make the fish available to the Environment Agency for inspection and further analysis.
If this is not possible, they are asked to send a sample of the scales. Trout and coarse anglers are asked to call the Environment Agency on 0800 807060. If unsuccessful, please return the salmon.
