Abstract

The invention relates to a net-free sound wave fishing method and device, and mainly relates to the field of aquatic product fishing. The invention provides the net-free sound wave fishing method. The method comprises the following steps of: dragging a plurality of sound wave generating modules to form a semi-enclosed sound wave array in the operation of a power driven boat, driving and gathering fish schools by using the sound wave array, driving the fish schools to a preset fixed area with a solid net, and carrying out fishing by the solid net in the area. The invention further provides a net-free sound wave fishing system. The net-free sound wave fishing system comprises the power-driven ship 1, the sound wave units 2, towing mooring ropes 3 and the fixing net 4, wherein each sound wave unit 2 comprises an upper cover plate 5, a cylindrical bin barrel 6, an electromagnet 7, a fixing block 8, an electromagnet fixing plate 9, a limiting column 10, an electromagnet return spring 11, a knocking head 12, a sound production plate 13, an elastic sealing mechanism 14, a return spring 15, a storage battery 16, a knocking control module 17, a control cabinet 18, a ship-shaped floating body 19, a sound wave unit pull cable 20 and the like.

Description

technical field [0001] The invention relates to a netless sonic fishing method and a device thereof, and mainly relates to the field of aquatic fishing. Background technique [0002] Trawling is a commonly used fishing operation method, which can actively and flexibly drag fish schools, but when the underwater environment is complex, it is easy to hang the net, and it is time-consuming and laborious to handle. [0003] The article "Fish Vocalization, Hearing and Its Application in Fisheries" published in the periodical "Marine and Limnological Bulletin" in 1983 said that different fishes have the ability to escape and respond to sounds with specific sound quality, specific frequency range, and specific intensity range. Avoidance behavioral response. This characteristic of fish provides a theoretical basis for "no-net" fishing. Contents of the invention [0004] In view of the above problems, combined with the fact that fishes avoid certain sound sources, the present inve...
