Police and river wardens are joining forces to tackle illegal salmon fishing in Ayrshire.
The River Doon District Salmon Fishery Board have teamed up with cops in a new initiative to combat poaching and other wildlife crime.
The Doon is home to the likes of wild Atlantic Salmon, the rare Freshwater Mussel, bird species such as Kingfishers and Dippers, and a reviving Otter population.
