Technical Field
The invention relates to the field of application of ocean light induced fishing saury to catch, in particular to a fish collecting system for rapidly and efficiently inducing and collecting ocean saury by utilizing lamplight and an operation method thereof.
Background
Illumination is one of the most important ecological factors in the marine environment, and is closely related to daily activities such as growth, development, reproduction, ingestion and the like of marine organisms. With the rapid development of photoelectric technology, the LED fishing lamp is widely applied in the fields of sea and aquatic products, so that the LED can replace natural light, ultraviolet light and high-radiation metal halide lamp light, directly influence the reproduction, development, state, quantity and distribution of marine organisms, and have profound influence on the marine fishing industry. The national fishery resources are rich, and the national fishery economic statistics of 2022 indicates that the national ocean fishing yield of 2488.91 hundred million yuan and the fishing yield of 1300.45 ten thousand t in 2022 are all in the front of the world, wherein the lamplight fishery has high specific gravity, especially the industries of the south sea area fishery and the ocean fishery. The notification center committee of the newly released agricultural rural office at the month of 2023 about further enhancing the performance of the North Pacific fishery has examined that a new Pacific saury resource maintenance management measure is passed, and the agricultural rural fishery administration makes a new Pacific saury catching quota allocation management scheme, allocates quota to various saury production enterprises and fishing vessels, and each enterprise and fishing vessel should be produced within a specified time and quota, and must not have quota or super quota operation, and must not be operated outside a specified time.
In the North Pacific ocean, all the board fishing net vessels are provided with LED fishing lamps for light trapping and fishing operation, and the LED fishing lamps of different manufacturers basically can realize red-white light switching, so under the quota system, the improvement of the fishing yield and the fishing efficiency by express delivery is particularly important, the improvement of fishing assisting equipment for light trapping and fishing operation and the optimization of operation details thereof are required, particularly the reasonable distribution of the fishing lamps on an operation ship body, the adjustment of the light angle on a large fishing lamp post, the concentration of the fishing lamp in a region from large to small, the improvement of the yield from the details, the improvement of the fishing efficiency of ocean fishing industry, the reduction of the fuel cost and the reduction of the carbon emission provide technical support for intelligent and accurate fishing of ocean fishing industry in China.
In the existing saury lamplight fish attracting technology, the specific operation process comprises the processes of attracting a fish swarm, concentrating and stabilizing the fish swarm, driving the fish swarm to gather, concentrating net lifting and the like, but in the net lifting stage, the fish swarm is not all located at a pumping position in the middle of net application, the phenomenon that the fish swarm escapes from two sides of a net to cause low net lifting efficiency is found, many fishes are attracted clearly, but due to the fact that equipment and a fishing technology are not in place, the attracted fishes escape too much, and the phenomenon that the single fishing amount is reduced is caused.
