Abstract

The invention discloses a starfish trapping device. The starfish trapping device comprises a frame body (1). The frame body (1) is cube-shaped. The exterior of the frame body (1) is covered by a netting (2), and the mesh diameter D of the netting (2) is less than or equal to 2 cm. The bottom of the frame body (1) is provided with two symmetrical inlet frames (3). The upper edges of the two inlet frames (3) support a baffle (4) together, and the inlet frames (3) and the baffle (4) have the same length as the frame body (1). The longitudinal end faces of the inlet frames (3) and the baffle (4) form an isosceles trapezoid with a shorter lower bottom edge. Multiple sinkers (5) are uniformly distributed at the opening edge of the netting (2), and the sinkers (5) are positioned at the inner sideof the bottom of the frame body (1). The starfish trapping device is simple in structure, skillful in design, and good in trapping effect without the personnel on-duty and operation.

Description

technical field [0001] The invention relates to a trapping device, in particular to a starfish trapping device. Background technique [0002] In the process of shellfish bottom sowing and breeding, avoiding the feeding of harmful organisms is the condition to ensure the yield of shellfish. Starfish is one of the main harmful organisms of shellfish bottom sowing and breeding. Starfish feed on shellfish bottom sowing seedlings, which will directly It affects the bottom sowing effect of shellfish, so how to remove harmful organisms such as starfish is the key to ensure the success of shellfish bottom sowing. Traditional methods include manual removal by divers, injection of toxins into the starfish, and release of harmful organisms on the starfish. However, the above methods are time-consuming and labor-intensive, with low work efficiency, or high operating costs, and are difficult to operate. Therefore need a kind of method or device that can solve above-mentioned problem now...
