Sound control fish luring device

Abstract

The invention relates to a fishing device, in particular to a sound control fish luring device which is used for luring fishes by an underwater sound control technology. The sound control fish luring device mainly comprises a soundwave signal source, a power amplifier, an underwater speaker and a power supply, and can be used for luring fishes in fishing activities, the fishing labor intensity can be obviously relieved, the energy consumption can be reduced, the fishing efficiency can be improved, and good stability and safety are obtained. The soundwave signal source mainly comprises a fish simulation phonotaxis signal generator, a fish phonotaxis production player, a multimedia player and a signal selector, the fish luring purpose can be realized through flexibly selecting the output soundwave signals of the simulation phonotaxis signal generator, the fish phonotaxis production player and the multimedia player according to fishing objects and working environments, so the fishing efficiency is improved.

Description

technical field [0001] The invention relates to a fishing device, in particular to a sound-activated fish luring device used for underwater sound-activated technology to lure fish. Background technique [0002] Fishing is one of the important links in fishery production. Advanced fishing gear (fishing tools) and fishing methods (fishing techniques) can reduce fishing intensity and improve fishing efficiency and catch quality. There are many kinds of fishing methods, which can be divided into dozens of fishing techniques such as trawling nets, gill nets, stretch nets, and light seine nets for different fish. Most of the fishing techniques use catching methods to drive fish into the net and start catching , because this type of fishing technology usually uses artificial (farming fishing) or power (fishing boat fishing) methods to catch fish, there are generally problems such as high fishing labor intensity, high energy (oil) consumption, and low catch per unit operating time. ...

Problems solved by technology

There are many kinds of fishing methods, which can be divided into dozens of fishing techniques such as trawling nets, gill nets, stretch nets, and light seine nets for different fish. Most of the fishing techniques use catching methods to drive fish into the net and start catching , because this type of fishing technology usually uses artificial (farming fishing) or power (fishing boat fishing) methods to catch fish, there are generally problems such as high fishing labor intensity, high energy (oil) consumption, and low catch per unit operating time.

Light purse seine is based on the phototaxis of fish, using lights to lure fish into the net and then catch them. However, due to the phenomenon of refraction, reflection and absorption of light in water, in order to increase the irradiation distance It is necessary to increase the power of the light source. Although this technology reduces the fishing intensity, due to the low utilization rate of light, the energy consumption is still very large

In addition, in order to adapt to the energy-saving emission reduction and low-carbon economy that is being vigorously promoted, the traditional fishing technology is no longer applicable to the requirements of energy-saving emission reduction and low-carbon economy. It is necessary to improve the traditional fishing technology or study new fishing technology to adapt to energy-saving emission reduction and low-carbon economy. Low Carbon Economy Requirements

[0003] Chinese invention patent 200910001037.5 discloses a sonic fish repellent device, which is mainly composed of a signal source, a power amplifier, a sounding device, a power supply, a casing, a switch and other components, and uses sound waves to lure and repel targets. It has the advantages of low cost, fast and far signal transmission, no time limit, no environmental pollution, etc.; but the signal source selection is relatively simple, and the sound wave signal cannot be flexibly selected according to the fishing object and the operating environment to achieve the purpose of luring fish
