Cage culture fishing system and fishing method applying same

Abstract

The invention relates to the technical field of fishing, in particular to a cage culture fishing system and a fishing method applying the system. The cage culture fishing system comprises a fishing boat body, a fish hold arranged inside the fishing boat body, a fish inlet and a fish outlet which are respectively connected with the fish hold, wherein the fishing boat body is further provided with a driving system for driving a water body to flow; the driving system comprises a pump, pipelines, and a power device which is connected with the pump and supplies power to the pump; the pipelines are connected with the pump; a fish pushing grating for pushing fishes to swim is arranged in the fish hold. According to the system disclosed by the invention, quick fishing can be realized, and the work efficiency is high, so that the manpower consumption for traditional fishing is reduced, the fishing time is reduced, and the system is extremely simple and convenient; the survival rate of fishes during the fishing process can be greatly increased, the method is simple in steps, and the effect of quick fishing can be realized.

Description

technical field [0001] The present invention relates to the technical field of fish harvesting, more specifically, to a fish harvesting system for cage culture and a fish harvesting method using the system. Background technique [0002] The deep-water cage for aquaculture consists of four parts: cage frame system, net clothing system, mooring system and supporting facilities system. The development and aquaculture application of deep-water cages in my country started in 1999. The supporting facilities for deep-water cage aquaculture are still in the development stage of individual product prototypes, and there is still a large distance from the demand for supporting technologies in the deep-water cage aquaculture industry. Therefore, today, when the supporting fishing facilities have not yet been applied in a large area, manual lifting of the net is still the main method. [0003] In the country, fish injuries or deaths due to long-term operation of cage fishing account for...

AI Technical Summary

Problems solved by technology

[0003] In the country, fish injuries or deaths due to long-term operation of cage fishing account for about 2-3% of the deep-water cage culture. Oxygen death; the annual economic loss due to improper fishing operation is as high as 30 million yuan

[0004] In addition, the existing methods of collecting fish and netting also have the following defects: a large amount of manpower is required, and improper operation is easy to run away fish, which leads to unsafe operation and is very inconvenient
