A fish trap is a trap used for fishing. Fish traps can have the form of a fishing weir or a lobster trap. Some fishing nets are also called fish traps, for example fyke nets. A typical contemporary trap consists of a frame of thick steel wire in the shape of a heart, with chicken wire stretched around it. The mesh wraps around the frame and then tapers into the inside of the trap. When a fish swims inside through this opening, it cannot get out, as the chicken wire opening bends back into its original narrowness. Contemporary eel traps come in many shapes and sizes and are constructed of many materials. In earlier times, traps were constructed of wood and fibre.
A fishing device
This utility model discloses a fish trap, including a drive structure, a float, and a folding fish cage. One side of the float is connected to the fish cage via a trapping component, which is connected to the drive structure via a combined transmission component. The trapping component includes two support blocks fixedly connected to the top surface of the float and the top surface of the fish cage, a corrugated telescopic tube A inserted through the inner wall of the two support blocks, and a corrugated telescopic tube B fixedly connected to one side of the fish cage at one end. The diameter of the corrugated telescopic tube B is greater than the diameter of the corrugated telescopic tube A. This utility model utilizes the sound of flowing water output from the corrugated telescopic tube B inserted through the side of the fish cage and from the corrugated telescopic tube A above the fish cage. Based on the fish's tendency to move in an oxygen-food-safe environment, it attracts fish into the fish cage, achieving the effect of attracting and catching a large number of fish. The barbel-shaped fish and shrimp inlet prevents fish from escaping after entering the fish cage.
