Description

Energy-saving flowing water body aquaculture tank

Technical Field

The invention relates to the technical field of aquaculture, in particular to an energy-saving aquaculture tank with a flowing water body.

Background

Aquaculture tanks are found throughout life. The aquatic product raised in the culture box can be artificially oxygenated by the oxygenator to improve the survival rate of organisms in the water body. However, the culture box has certain defects, because the living organisms in each part of water body have different survival amounts and different oxygen consumption amounts, the oxygen increasing device increases the oxygen content of the part of water body where the oxygen increasing device is positioned by increasing the oxygen of the water body, and therefore, the culture box is only suitable for small culture boxes. In addition, the water in the culture box does not flow, so that the enrichment of water nutrition is easy to occur, the natural oxygen dissolving capacity of the water is very low, oxygen is added by the oxygenator basically, and the consumed energy is very large.
