The social behavior of fish is the key to the success of handle-fishing-landing-net. In the natural environment, fish tend to form large groups, and this clustering behavior provides fishermen with fishing opportunities to a certain extent. Fishing nets take advantage of the propensity of fish to flock together and increase the success rate of fishing by setting up large areas of fishing nets to surround the fish.
The way fish swim in the water is also the premise that handle-fishing-landing-net can play a role. Fish swim in the water mainly rely on the swing of the body and the flap of the fins, which allows them to move quickly and flexibly in the water. Fishing nets take advantage of the inertia of fish swimming, by designing the shape and size of the network port and the mesh, making it difficult for fish to escape during swimming. The mesh of the fishing net can be designed to be small in size so that most fish cannot pass through, thus achieving the effect of fishing.
Nets can also take advantage of fish's escape response. When fish are threatened, they often exhibit evasive behavior, trying to leave the danger zone. Fishing nets cleverly exploit this response, trapping the fish in the net by rapidly tightening the handle-fishing-landing-net to block their escape. This strategy can minimize the escape rate of fish and improve the efficiency of fishing.
