The invention discloses a floating and sinking device for a bionic robotic fish and the bionic robotic fish. The floating and sinking device comprises a base plate and floating and sinking parts. The floating and sinking parts are symmetrically arranged on the two side surfaces of the base plate. Each floating and sinking part comprises a dielectric elastomer film layer, an electrode layer, a conductive assembly and an elastic assembly. The dielectric elastomer film layer is arranged on the base plate, and an arc-shaped first cavity is formed between the dielectric elastomer film layer and the base plate; the electrode layer wraps the dielectric elastomer film layer; the conductive component is electrically connected with the electrode layer; and one end of the elastic assembly is arranged on the base plate, and the other end is connected to the dielectric elastomer film layer. According to the floating and sinking device for the bionic robotic fish, the size of the floating and sinking device can be changed by controlling a voltage value of an external power source connected to the conductive assembly so as to change the buoyancy of water borne by the bionic robotic fish, and then the floating, floating stopping and sinking actions of the bionic robotic fish are achieved. Therefore, the floating and sinking principle similar to that of fishes is achieved, and the bionic performance of the floating and sinking device is better.
