Anglers have been asked to report catches and sightings of an invasive species of salmon in Scottish rivers.

Pink salmon are native to Pacific Ocean waters but have spread to parts of northern Europe after being released into rivers in Russia in the 1960s.

“Unprecedented numbers” of the fish were found in Scottish rivers in 2017, and high numbers were again seen in 2019.

The salmon have already been caught this year in the Ness in the Highlands. Fisheries Management Scotland (FMS) has asked anglers to report where else the fish have been found.
