The Angler Recording Project
Recording the Southwest's Natural Heritage
If we want to establish sustainable fisheries in Europe, we need to understand as much as possible about the distribution and abundance of our species'. For commercially important bony fish such as cod this is already reasonably well known. For the sharks, skates and rays however we know much less. To help with this, the Shark Trust is asking anglers to record their catches of all sharks, skates and rays (including dogfish) in the southwest, including Cornwall, Devon, Dorset, Somerset, Avon and the Scilly Isles.
