British anglers have been told to watch out for an alien salmon species that is normally native to the chillier waters of the Pacific and Arctic Oceans.
Eight specimens of wild pink salmon have been caught in the rivers Tyne and Wear, and off the coast of South Shields. The fish is native to the north Pacific basin and its surrounding rivers, and is the smallest and most common of the Pacific salmon.
