A fisherman takes a net from one corner of the boat to catch fish in the lake and jumps to target the fish. This is an old method of fishing. Fishermen take a boat around the lake to look for fish. Whenever they realize the shuttled of the fish, the fishermen jump from the other corner of the boat with their nets to catch the fish. Since the water inside the lake is low and clear, when the fish go to hide in the mud in fear, steam rises from the bottom of the water. Seeing these vapors, fishermen can understand that there are fish here.
