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...
