Abstract

The invention discloses a sampling net for hairy shrimp, which comprises: a tensioning device and a fishing net connected to the tensioning device, the tensioning device includes two support rods, and the two support rods pass through a bolt connected, the pole can rotate around the length direction of the bolt, and the length direction of the bolt is perpendicular to the length direction of the two poles; the connection position between the fishing net and the pole is close to the free end of the pole, An edge of the opening of the fishing net is provided with a float, and the edge provided with the float is an edge of the fishing net close to the pole, and the lower opening of the fishing net is connected with a shrimp fetching part; the shrimp fetching part is A cylindrical structure, the side wall of the shrimp fetching part has a through hole, the internal space of the fishing net is connected with the internal space of the shrimp fetching part through the through hole, and a float is provided on the edge of the mouth of the shrimp fetching part. The invention realizes rapid sampling of hairy shrimp, and meanwhile has simple structure and low cost.

Description

technical field [0001] The invention relates to a fishing device for aquatic product samples, which is used for precise fishing through the cooperation of a long rod and a net bag, in particular to a fishing net for sampling hairy shrimp. Background technique [0002] Hairy shrimp often live in groups in estuaries, harbors and islands, in shallow sandy bottom seas with a water depth of no more than 50 meters, and have not been found in pelagic or deep sea areas. The Chinese hairy shrimp produced in the Bohai Sea inhabits the middle and lower layers of seawater, and sometimes rises to the surface in summer. Because of their weak swimming ability, they go back and forth with the ebb and flow of the tide. In winter, the water temperature drops and moves slightly deeper. After spring, spawn near the estuary or near the shore in shallow water; as the water temperature gradually rises, the scope of the spawning ground expands day by day. The male and female shrimps mate after t...
