Anglers across Scotland have been asked to report catches and sightings of a predatory species of pink salmon.
Pink salmon native to Pacific Ocean waters have spread to parts of northern Europe after being released into rivers in Russia in the 1960s. They are now the dominant species there – prompting fears they could harm the native Atlantic salmon here.
Now they have been caught in the River Ness, and the fishery board is asking others to be vigilant and report any sightings.
There is little known about how the new species will impact the native Atlantic salmon, but competition for food and habitat may harm established species.
