Fish bombing - Early history

During the Second World War, a number of navy personnel operating in Asia made use of grenades to catch fish. The blast from a single grenade killed many fish, large and small, and the ones that floated to the surface were easily netted in quantity. The technique of catching fish using underwater explosions quickly caught on with local fishermen as it is simple and ruthlessly efficient, at least as far as the time taken to catch the fish is concerned.
