Recirculating aquaculture container and breeding system

Abstract

The invention provides a recirculating aquaculture container, and belongs to the field of fishery equipment and technology. The recirculating aquaculture container comprises a culture container, a manure storage container and a sewage discharge device; the upper portion of the culture container is composed by surrounding of at least one permeable side wall and a remaining non-permeable side wall,the lower portion of the culture container is a dirt-contaminated side wall which is inclined and transited from the lower end of the water-permeable side wall and the lower end of the non-permeable side wall to the center, and the lower end of the dirt-contaminated side wall is connected with the manure storage container; the manure storage container is a hollow container with an open upper end,and the manure storage container is communicated upwardly with the culture container; an openable manure sinking switch is arranged between the manure storage container and the culture container; themanure storage container and the manure discharge device are communicated, and the manure discharge device is used for discharging the stored manure from the manure storage container. The invention also discloses a recirculating aquaculture system.

Description

technical field [0001] The invention relates to fish farming technology and equipment, in particular to a circulating aquaculture container and a culture system. Background technique [0002] The global recirculating aquaculture industry has developed rapidly and has become the fastest growing pole in the aquaculture model. It is water-saving, land-saving, and convenient for site selection; water temperature and water quality are controllable; biologically safe and reliable, with little or no use of drugs, and good quality ; High output; Pollution controllable, effective emission reduction and other advantages. [0003] Recirculating aquaculture is an advanced form of facility aquaculture. Through engineering technology and facilities and equipment, an optimal growth water environment is created for the aquaculture production system to achieve high yield, high quality, high efficiency and environmental protection. Facility aquaculture accounts for about 10% of the total aqu...

Problems solved by technology

However, in the existing breeding equipment, the feces are in contact with the cultured organisms for a long time, and the feces are easily dispersed, which increases the difficulty of settlement, affects subsequent collection, concentration and transfer out of the water body, and reduces the pollution of the breeding water area to a limited extent.
