What is the effect of hand-cast net fishing in the United States?

The net was thrown into the underwater ground in a large area, and the fish were covered with the net. Slowly pull the net rope, so that the bottom rope with lead pendant is close to the ground, and at the same time lift the bottom rope to the top of the net. At this time, the net clothes form a circular pocket, and the fish is put in the pocket. Continue to pull the net rope to make the net water flow out of the ground. When taking fish, hold the top of the net by hand and lift it, loosen the rope of the net, so that the bottom net falls, and the net deforms into a straight shape from the pocket, and the fish falls to the ground in the net to take it.

1. This method can only be used for fishing in shallow water. The edge of the net is covered with lead pendants. After the net is spread out, it quickly sinks to the bottom of the water and pulls up the net rope (this net rope is connected in series with the whole net edge! When closing the net, pulling the rope is like tightening the rope at the mouth of the bag and trapping all the fish in the net. When slowing down, the pendant will gradually approach the bottom of the water. Then slowly lift it up. The fish caught in the net will not fall because of the pendant.
