Invasive pink salmon found in Scotland

Anglers have reported non-native Pacific pink salmon in some of Scotland’s most pristine rivers, raising fears they could harm native populations.

Under the Wildlife and Countryside Act 1981, pink salmon, Oncorhynchus gorbuscha, is an invasive non-native species, which means it is an offence to buy or release it into the wild.

While native to Pacific Ocean waters, the fish has spread to parts of northern Europe, such as Norway, since their release into rivers in Russia in the mid-20th century. 

There are now fears that it could establish itself in Scottish rivers and compete for food with the native Atlantic salmon.
