Full-submersible closed culture fishing ground

Abstract

The invention provides a full-submersible closed culture fishing ground. The ground comprises a culture tank, a buoyancy cabin, a circulating water pump, a wave energy power generation device and a material replenishment and supply buoy platform. A water inlet pipe capable of going deep into a deep cold water layer is arranged at the bottom of the culture tank. The buoyancy cabin is arranged at the periphery of the bottom of the culture tank; the circulating water pump is communicated with the interior of the culture tank; the wave energy power generation device is connected with the circulating water pump and supplies power to the circulating water pump; and the material replenishment and supply buoy platform floats on the water surface and is connected with the culture tank through a hose. The technical problems that according to a net cage culture manner in the prior art, culture water is the same as external water, cold water cannot be kept in a culture area, and the cold water fish culture industry cannot be developed are solved. Circulating exchange between warm water in the culture tank and cold water in the external deep water layer is achieved, it is guaranteed that the interior of the culture tank is a cold water body, and therefore the technical effect that large-scale cold water fish culture is conducted in a warm heat zone water area through marine resources in China is achieved.

Description

technical field [0001] The invention relates to the technical field of fish farming and marine engineering equipment, in particular to a fully submerged closed fish farm. Background technique [0002] At present, the aquaculture field mainly relies on the natural environmental conditions of the sea area to breed corresponding fish species. For most of the sea areas in my country, which are located in the temperate zone, the water surface temperature in the temperate zone is relatively high, and it is impossible to scale up high-value-added cold-water fish, and it is difficult to develop high-end fish. In the aquaculture industry, the temperature of the water layer with a water depth of more than 100m is relatively low, which is more suitable for the growth of cold-water fish. However, due to the depth of the cold water layer, the use of traditional deep submersible pumps to extract deep cold water consumes a lot of energy and is difficult to achieve. At the same time, when a ...

Problems solved by technology

[0005] The embodiment of the present invention provides a fully submersible closed fish farm, which solves the cage culture method in the prior art. The culture water body and the external water body are the same, and the cold water cannot be kept in the culture area, so there is a problem that cold water cannot be carried out.
