Anglers in Scotland have reported several captures of fresh run non-native Pink Salmon (Oncorhynchus gorbuscha). Some captures have also been reported in some salmon net fisheries in Scotland and both rod and net fisheries in England and Ireland. These fish are not native to Scotland and are likely to have ‘strayed’ from some of the rivers in northern Norway or Russia.
