Fish seawater-recirculation aquaculture net cage

Abstract

The invention relates to a fish seawater-recirculation aquaculture net cage. The fish seawater-recirculation aquaculture net cage comprises a fish culture pond, a filter tank, a protein decomposition tank, an ultraviolet-ray disinfection lamp which is arranged above the protein decomposition tank, an oxygenation tank, a regulating tank which is communicated with the oxygenation tank by a pipeline, communicated with the fish culture pond by a pipeline, and used for regulating the salinity and the temperature of seawater, a water quality monitor which is arranged in the fish culture pond and used for monitoring the water quality of the fish culture pond, an oxygen concentration sensor, a salinity sensor, a temperature sensor, and a controller which is connected with a solenoid valve, the ultraviolet-ray disinfection lamp, an aeration aerator, the water quality monitor, the oxygen concentration sensor, the salinity sensor and the temperature sensor. According to the fish seawater-recirculation aquaculture net cage disclosed by the invention, investment cost of seawater recirculation aquaculture and energy consumption in a culture process can be greatly reduced; the utilization rate of seawater resources is increased; and the fish seawater-recirculation aquaculture net cage is energy-saving and environmentally-friendly, and has the advantages of being simple in process flow, less in water treatment equipment, and the like.

Description

technical field [0001] The invention relates to a seawater culture appliance, in particular to a seawater fish culture net cage with circulating water. Background technique [0002] With the development of my country's market economy, the mariculture industry has also developed rapidly. At present, most of the mariculture models in my country adopt the traditional extensive farming model. In the process of aquaculture, a large amount of metabolites and residual bait are produced, and direct discharge will cause environmental pollution. [0003] In addition, there are many problems in seawater fish culture net cages, including: seawater fish culture adopts bamboo or wooden rafts to float on the sea surface, and then hangs them with fishing nets under the bamboo and wooden rafts for cultivation. This breeding tool cannot withstand typhoon and big waves. The impact caused heavy losses, and this kind of breeding tool cannot use deep water bodies, which leads to a large waste of ...

[0003] In addition, there are many problems in seawater fish culture net cages, including: seawater fish culture adopts bamboo or wooden rafts to float on the sea surface, and then hangs them with fishing nets under the bamboo and wooden rafts for cultivation. This breeding tool cannot withstand typhoon and big waves. The impact caused heavy losses, and this kind of breeding tool cannot use deep water bodies, which leads to a large waste of water resources; artificial breeding requires a lot of labor, and artificial feeding is required, and bait feeding can only be based on experience, and scientific feeding cannot be done, resulting in serious waste
