Structural reasons for fishing nets

    As we all know, there are many lead pendants at the very edges of this type of fishing net. When the net is forcefully spread, desire naturally falls into the water. When the lead pendants sink, they fix the scattered fishing net into a scattered range, so that the net covers the fish under the net. At the outermost circle of the fishing net, there is also a rope specifically designed to tighten the net. This rope is similar to the net pocket we usually use. If we pull hard, it will tighten the outermost circle of the fishing net and press it against the bottom of the water to tighten the net until the entire net is tightened before dragging it ashore, which will concentrate the fish in the center of the net.

The reason for the fish itself

    You may not know that due to the growth structure of the fish's eyes, fish cannot see the mesh of the fishing net at close range. Therefore, when a fish is caught in the net, it will not rush forward, but will turn when it touches the net. This way, the fish will continue to circle inside the net until it is caught by the net, and will not sink or escape. This is the same as goldfish circling in a circular bathtub.

    In fact, this principle is very simple. We can conduct an experiment by taking a hammock used by our own children and pulling the rope connecting the two ends to understand. If there are any other unclear points, please leave a message.

    It seems that the subject is not a person from a water town or a child who grew up in a rural area. I am curious and confused about the ability to catch fish with the fishing net that has been thrown out. Why are fish so "foolish" that they won't run away?

    Fishing net: This type of fishing net is spread out like a conical shape: a long rope is tied to the "pointed" position at the top, and the length of the rope is controlled by wrapping it around the fisherman's arm; The opening of the net is large, and the edges of the opening are closely connected with lead pendants, which help the fishing net sink quickly and effectively block the escape path of fish in the water in advance. Of course, there may also be some fish that miss the net.

    Fishing with nets: This requires experienced fishermen to operate, and ordinary people cannot control fishing with nets. This is a learned skill. However, it should be noted that the depth of the water should be determined, as the water has buoyancy, even if the fishing net has a plumb bob, there is also a process of sinking. During this process, if the water is too deep, such as water exceeding ten meters deep. As the fishing net entered the water, the sound of the lead breaking through the water had already entered the water. The water was too deep, and the plumb bob of the fishing net had not yet reached the bottom, causing the fish to run away; It is necessary for the fishing net to sink into the water before the fish can react, in order to catch the fish.

    Lifting the net: This step is also a very important measure, whether the harvest is abundant or not depends entirely on the operator's technical ability. After the net sinks to the bottom, the post net operator begins to retract the net: it needs to slowly pull and pull the "tip" side of the net, and according to the terrain of the pond, shake the net while pulling, which can make the lead at the bottom of the net slowly retract more evenly. The heavy lead is like a pocket of "tie rope"... When the net comes out of the water, the lead has already "tied" the bottom of the net, and all the fish in the net are caught. The person who scatters fish with a net is constantly repeating the action again and again to complete the fish scattering homework.
