Bait structure capable of attracting fish through bubbles underwater

The embodiment of the utility model discloses an underwater bait structure capable of luring fish through bubbles. The underwater bait structure comprises a fish body structure, a front through hole structure, a middle through hole structure and a rear through hole structure. The body is provided with a fish body line cavity for storing and exchanging air and water, the fish body line cavity in the air discharges water through inlet air, and the air is discharged from the bubble holes through inlet water under the water. When the body leaves the water surface, all the through holes are opened, air enters the fish body line cavity, and water in the line cavity is sequentially discharged from the middle through hole, the rear through hole and the like. In the throwing process of the body, the gravity center of water which is not discharged is increased and transferred forwards, the throwing distance is farther, and residual water continues to be discharged. When the fishing line is pulled, the instant accelerat
