Description

Squid fishing device

Technical Field

The utility model relates to an industry fishing field specifically is a squid fishing device.

Background

Currently, there are various sound generators for attracting and gathering fish and marine invertebrate organisms to achieve the purpose of intensive fishing. Known underwater acoustic devices include electrically operated underwater acoustic emitters or piezo ceramic underwater acoustic emitters, including recorders recording a series of acoustic signals, such as the sound of eating a seriola quinqueradiata, the sound of backing a boat, a series of pulses at a frequency of 600Hz, rain and amplifiers. During the fishing process, the emitter is put into the water from the side of the ship, and the recorder and the signal amplifier are arranged on the ship.

The squid is acted on by sound vibration transmitted in the water body, and the light field attraction effect can be enhanced by using the sound signal, so that the squid catching efficiency is improved.

However, the known devices have a number of significant drawbacks, namely the insufficient efficiency of attraction and concentration of the squid due to its rapid adaptation to a single sound, in addition to the low quality of the transmitted signal of the electrodynamic or electromagnetic field. Because the used electrodynamic or piezoelectric ceramic transmitters distort the reproduced bio-signal when the operating band in the low frequency region is extended. Furthermore, increasing the intensity of the emitted sound from a distance to attract the fishing subject is not always acceptable, because unnatural strong acoustic signals can scare away squids located near the emitter. Further, it was found that the squid-biting fishhook attracted by light and sound is insufficient in strength due to the spatial motion lacking the sound field. A fish sound simulation device is known, which comprises a compressed air source, wherein the outlet of the compressed air source is connected with a control unit, the control unit comprises an electromagnetic valve, a time relay and pneumatic emitters connected in series with fish sound signals through flexible pipes, and each group of emitters is formed by combining three emitters. Each emitter of the fish sound signal is provided with a limit check valve and a tank which is always larger in volume than the tank of the previous emitter.

The device has the disadvantage of low effective influence on the squid due to the lack of vertical motion component of the fish acoustic signal emitter.

It is well known that immersed and pop-up objects also attract squid, increasing the sensation of movement and stimulating the squid' puffs towards the hook. Therefore, the lack of vertical movement of the sound field is obviously the defect of the device and also the reason of low strength of the squid-biting fishing tackle in the squid-fishing process.

Known underwater acoustic device-a fish sound simulator that collects fish in the area of action of the fishing gear. The fish sound simulator is characterized in that a signal electron generator, a power supply and a power amplifier are arranged in a shell of the fish sound simulator, and the fish sound simulator is connected to an underwater acoustic transducer in a spherical piezoelectric ceramic head (positive buoyancy) form through a cable.

A major drawback of this and similar devices for controlling fish behavior is that the fish sound simulator is not able to emit fish sounds efficiently, since it cannot guarantee a broad band spectrum of the sounds emitted by it, which is characteristic of most fish signals, especially in the low frequency region of the spectrum (below 1kHz), corresponding to the hearing region of most fish and marine invertebrate organisms harvested. The more efficient sound emission of piezoelectric transducers is limited to the vicinity of the resonance frequency, while the low frequency resonance can only be achieved by the large size of the simulator active device, which complicates its use in fishing and, in addition, implies high costs for the transducer.

The technical essence is that the closest to the reported solution is a squid catching device, which comprises a compressed air source and an outlet control unit, a fish sound pneumatic emitter, a check valve and an air storage tank, the volume of which exceeds the volume of the previous air tank and are connected in series by a flexible pipe, the compressed air source and the control unit are placed on a ship, the pneumatic fish sound emitter, the check valve and the air storage tank are placed outside a radial plane of a ship body, the air tanks are provided with flexible sheaths and are made of elastic materials, and each air tank is provided with a depth-fixed counterweight, and the weight of each air tank is larger than the weight of the previous counterweight (Russian Federal patent No. 2338374, IPC A01K79/00, published in 2008).

Disadvantages of the known device include:

the energy level of the transmitted signals is limited by the structure of the fish underwater sound pneumatic transmitter, so that the attraction range of the fish underwater sound pneumatic transmitter to the squids is limited, the sound wave influence area of the squids can be enlarged by increasing the power of the transmitted sound, and the squids near the pneumatic transmitter can be startled by an over-strong signal;

the signals emitted by the pneumatic emitters of fish connected in series are formed in horizontal turns from side to side, and each next signal is added to the previous one, these signals being sounded simultaneously, and when the supply of compressed air is stopped, the signals are also formed starting from the pneumatic emitter close to the source. However, the sequential movement of sounds under natural conditions is a common phenomenon of fish swimming. Under natural conditions, the fish school signal is randomly formed in any direction. Thus, the known devices do not reflect the real conditions of the swimming fish and the movements thereof in a sea environment, thereby limiting the fishing area and reducing its efficiency.

The air bubbles formed by the fish sound pneumatic emitter under the ship are positioned in the shadow space of the light emitted by the lighting lamp ring, so that the attraction of the light shadow to the squid is small, and the light shadow is just the motion characteristic of small fish under natural light sources such as moon, stars and the like.

The squid density (convergence degree) at different distances from the ship and the adaptive relation of the sound source level of the emission signal relative to the squid convergence distance and the like are not evaluated, so that the efficiency of attracting and keeping the squids in a fishing area is greatly reduced.
