Problems solved by technology

Due to the large area of ​​the fenced breeding sea area and the undulating seabed topography, it is difficult to use nets for precise fishing operations; marine ranches also face the problem of releasing fish. Due to the complex terrain of marine ranches and artificial fish reefs and other components, traditional trawls, seines, etc. are difficult to use

Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings.

[0035] see Figure 1 to Figure 3 , specific embodiment 1, a kind of directional sound control fish driving fishing method, is characterized in that, comprises the steps:

[0036] Step 1, net cage 2 is set on one side inside the fence. Fence 1, stakes are connected with net clothing to block the sea area and carry out fish culture. The present embodiment uses the water depth of 15 meters as the design description of the fence. The net cage 2 comprises a net cage frame 11 and a net cage net clothing 12 wrapped outside the net cage frame. The steel chains on the edge of the cage net clothes 12 are connected with steel chains to form sinker steel chains 15, so as to keep the net cage net clothes in the state of opening under the action of water flow. The specifications of the iron chains are counterweighted as required. 3-5kg / m. Net cage frame 11 is the framework that ...

Abstract

The invention relates to the technical field of fishing. A directional sound control fish-repelling fishing method comprises the following steps that firstly, a net cage is arranged on one side of the interior of a fence, an opening of the net cage faces outwards, and the opening end of the net cage is connected with a blocking net used for closing the opening of the net cage; 2, transducer arrays are arranged, the transducer arrays comprise at least two transducer arrays which are arranged from far to near along the distance to the net cage, each transducer array comprises at least two transducers, and each transducer is connected with a floating ball; 3, the transducer array sequentially works according to the distance between the transducer array and the net cage, and then the fish school is driven to swim into the net cage. Based on the characteristics that sound signals are small in attenuation, high in propagation speed and wide in influence range in water, fish behavioral research shows that a driving effect can be generated on the large yellow croakers under certain sound pressure intensity, a transducer array can be set according to the principle, directional driving and fish collection of the cultured large yellow croakers can be achieved, and concentrated and efficient fishing can be achieved.

Description

technical field [0001] The invention relates to the technical field of fishing, in particular to a sound-activated fishing method. Background technique [0002] The construction of fence breeding facilities is to use the seine to fence a large area of ​​water for stocking breeding. Pasture fence farming has developed into a characteristic aquaculture model in my country's coastal waters. Due to the large area of ​​the fenced breeding sea area and the undulating seabed topography, it is difficult to use nets for precise fishing operations; marine ranches also face the problem of releasing fish. Due to the complex terrain of marine ranches and artificial fish reefs and other components, traditional trawls, seines, etc. are difficult to use. Contents of the invention [0003] Aiming at the problems existing in the prior art, the present invention provides a directional sound-activated fish driving fishing method, which has solved at least one of the above-mentioned technical...
