In the wholesale of fishing nets, there is a type of trawling, and its use is not difficult, but it must be known in advance.
Before using trawling, it is necessary to remove the debris from the pond. The large unevenness or deep pit at the bottom of the pond will affect the fishing effect. Be sure to use the net gear correctly. The length of the net should be at least 1.4 times the width of the fish pond. The height of the net should be at least 2 times the depth of the water, and the location of the net should be mastered. The shallow water should be off the net, and the deep water should be netted. When the wind is blowing, you should drop the net at the end of the downwind pond and wind the net. The bottom should form an angle with the bottom of the pool when trawling. When the net is up, the fish is dense, mainly to prevent the fish from escaping from the bottom.
The starting point of the net should be 30-41 degrees from the slope of the pool and the horizontal plane, and the slope is flat and free of debris. When trawling, pay attention to the speed should not be too fast and not too slow. If the drag speed is too fast, the bottom is not easy to step on, and the bottom and the bottom of the pool are easy to escape.
