This is an amazing technique. Filmed back in the 1920s and 30s, these are Belgian horse fishermen trawling up shrimp. I wonder if anyone still fishes this way?
Filmed on August 12, 1934 and on July 18, 1929. Koksijde (Belgium), Coxyde, North Sea coast in the southwest of the Flemish province of West Flanders. Oostduinkerke. De Panne (Belgium), La Panne. There’s a great piece at Atlas Obscura here.
