Compared with the barbed hook, the barb-free hook has a better effect in fishing silver carp and bighead carp, and it is easy to be inhaled in the process of drifting. After the fish is caught, the trauma and struggle are less, and it is relatively easy to lift the rod and take the fish away. Although the barbed hook is easy to catch fish, after the fish is injured, the struggle of the fish is often more intense, and the sub-line is often broken, which leads to the decoupling and deviation of the fish, so it is better to have a red hook without a red hook.
