ORANGE-tipped sea squirt, wireweed and rainbow wrack are among the deadly dozen alien species placed on an “unwanted list” of potential invaders drawn up by marine experts.
The Marine Spatial Planning Team at Shetland’s North Atlantic Fisheries College (NAFC) Marine Centre, backed by Marine Scotland, have produced a definitive guide to help fish farmers and fishermen to identify non-native species that could pose a potential threat to area’s fishing and aquaculture industries.
Some of the alien invaders have already been found off the coast of the British mainland, including the carpet sea squirt, a filter feeding marine invertebrate from Japan which has managed to hitch a lift around the globe on boat hulls and in ballast water.
