Abstract

The invention provides a three-layer gill net for capturing silver carp and bighead carp. The three-layer gill net comprises a head net wire rope and a foot net wire rope, wherein a first-layer gill net mesh, a second-layer gill net mesh and a third-layer gill net mesh are jointly connected with and arranged between the head net wire rope and the foot net wire rope; automatic retraction and extension lines are arranged on the third-layer gill net mesh and connected with automatic retraction and extension fish bags which can realize automatic retraction and automatic extension under the action of the automatic retraction and extension lines; the tops and bottoms of the first-layer gill net mesh, the second-layer gill net mesh and the third-layer gill net mesh are respectively connected with the head net wire rope and the foot net wire rope; floats and weights are arranged on the head net wire rope and the foot net wire rope, respectively; and the first-layer gill net mesh, the second-layer gill net mesh and the third-layer gill net mesh can realize natural unfolding of the three-layer gill net for capturing the silver carp and the bighead carp in water under the actions of the floats and the weights.
