"Circle" fishing. Fishing using a "circle", i.e. a large float with a rod in the middle. The float is placed on the water surface, the fishing-line and the sinker with a triple hook with a sprat go under water. When a fish takes the sprat, the float turns upside down. The lower part of the float is painted white, and the upper - red. The stamp features an episode of circle fishing, with the floats and a pike, a perch, and a zander.
