Otter fishing is a fishing technique which uses trained otters to fish in rivers. This method has been practised since the 6th century in various parts of the world, and is still practiced in southern Bangladesh.
Otter fishing has been practiced historically in a number of regions including Central Europe, Northern Africa, the British Isles, Scandinavia, South Asia, Southeast Asia and China.
Two otter species have been primarily used in otter fishing – the European otter (Lutra lutra), chiefly in Europe and North Africa, and the smooth-coated otter (Lutrogale perspicillata), mostly in South Asia and China.
