Assembled stable sinking and floating deep sea culture net cage and using method thereof

Abstract

The invention relates to the technical field of deep-sea culture, in particular to an assembled stable sinking and floating deep sea culture net cage and a using method thereof. The assembled stable sinking and floating deep sea culture net cage comprises a frame system, a buoyancy adjusting system, an auxiliary buoyancy stabilizing system, an anchoring system, an inner and outer net system, a netcleaning system, an underwater measurement and control and oxygenation system and a fish collecting system. The culture net cage has the advantages that the assembled structure is beneficial to standardized manufacturing and installation and facilitates corrosion prevention and maintenance; the stability during sinking and floating is enhanced by using a method of adjusting and controlling auxiliary buoyancy; layered culture is conducted, and a three-dimensional food chain and a culture ecological chain are constructed; remote management and control can be realized through a mobile terminal according to real-time data of an Internet of Things management system and a water area information acquisition center; buoyancy is adjusted by adjusting the water amount, sinking and floating are controlled, and regular net cleaning and maintenance are facilitated; dissolved oxygen is supplemented layer by layer, so that the culture density can be multiplied; and fish automatically swims into a cabin along a fish collecting water slideway, so that the manual operation cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of deep-sea aquaculture, in particular to an assembled deep-sea aquaculture net cage with stable ups and downs and a use method thereof. Background technique [0002] The frame of the traditional plastic deep-sea aquaculture cage and the net clothing do not form a whole, and there is a lack of supporting carriers for intelligent installation, Internet of Things, and dissolved oxygen supplementation; the single aquaculture model, extensive management, and high operation and maintenance costs restrict the development of the deep-sea aquaculture industry. develop. Due to the congenital defects of the cage structure, the depth of the breeding net is more than 7 meters, and the utilization rate of the breeding space and the breeding density are extremely low. The annual cost of cleaning and harvesting fish in a single-mouth net cage is as high as tens of thousands of yuan, which also increases the mortality of c...

Problems solved by technology

Some merchants even falsely advertised, exaggerating the service life and wind and wave resistance, resulting in huge losses for aquaculture enterprises in the south and serious idleness of the breeding cages in the north.
