Embodiment 1

[0062] Such as figure 1 , 3 The embodiment shown is a kind of fishing device for purse seine with optical cable on water, comprising a boat-shaped floating body 1, a power switch 19 arranged on the floating body, a controller 2 arranged in the front part of the floating body, a rudder motor 3, a GPS locator 4, Storage battery 5, storage battery for power supply, light intensity adjustment device 6 located in the rear of the floating body;

[0063] Such as Figure 5 The airtight cavity 7 shown, the luminous body 8 arranged in the airtight cavity; the five optical cables 9 arranged at the rear of the buoyant body and extending into the airtight cavity and sealingly connected with the airtight cavity;

[0064] Such as figure 2 Shown, be located at the rudder 10 on the lower surface of the floating body, 5 guiding vertical pipes 11 for accommodating the optical cable, and the propeller motor 12 and the propeller 13 located at the bottom of the floating body; the light intensit...

Embodiment 2

[0077] Embodiment 2 includes all structure and method parts in Embodiment 1, and also includes a vibration sensor 16 located in the floating body, and the vibration sensor is electrically connected to the controller; it also includes the following steps:

[0078] Step 610, the standard signal-to-noise ratio SNR is set in the memory 标准 , the rotation speed C1 of the propeller motor is 30 rpm, and the rotation speed C2 is 50 rpm; during the movement of the fish seine device on the water, the vibration sensor detects the vibration signal of the floating body, and the controller selects the current time within 4 minutes. A section of detection signal Spec(t);

[0079] Step 620, data processing:

[0080] The controller inputs the detection signal Spec(t) into a stochastic resonance model Among them, V(x, t) is the potential function, x(t) is the Brownian motion particle trajectory function, a, b are the set constants, ξ(t) is the external noise, D is the external noise intensity...

Abstract

The invention discloses an aquatic optical cable purse net fish attracting device and a fish catching method. The aquatic optical cable purse net fish attracting device comprises a boat-shaped floating body, a power supply switch arranged on the floating body, a controller, a rudder turning motor, a GPS positioning instrument, a memorizer, a storage battery for power supply, a light intensity regulating device, an airtight cavity, a light-emitting body arranged in the airtight cavity, a plurality of optical cables, a rudder arranged on the lower surface of the floating body, vertical guide tubes equal to the optical cables in number and used for containing the optical cables, a propeller motor and a propeller, wherein the controller, the rudder motor, the GPS positioning instrument, the memorizer and the storage battery for power supply are arranged in the front portion of the floating body, the light intensity regulating device and the airtight cavity are arranged in the rear portion of the floating body, one end of each of the optical cables extends into the airtight cavity and is in sealed connection with the airtight cavity, the propeller motor and the propeller are arranged under the floating body, and the other end of each of the optical cables penetrates through the floating body to be exposed out of the lower surface of the floating body. The aquatic optical cable purse net fish attracting device has the advantages of being wide in fish attracting range and good in stability, providing convenience for purse net fishing and being not easily overturned.

Description

technical field [0001] The invention relates to the technical field of fishery, in particular to a fishing method of an above-water optical cable purse seine fishing lure device capable of guiding fish to swim to a predetermined positioning point. Background technique [0002] Although the phototaxis response of fish is affected by many internal and external factors and produces a variety of performances, phototaxis is one of its abilities to adapt to the living environment. [0003] The light intensity at which the maximum phototaxis rate is generated in the phototaxis reaction of fish is called the suitable illuminance. The fish gathering technology in light fishing production is based on the appropriate illumination. In the underwater light field of the same light, different phototaxis fish will gather in their own unique suitable illumination area; if the illumination intensity of the light increases or decreases, the fish will follow the movement of the appropriate ill...
