Description

Circulating water fishery aquaculture system

Technical Field

Background

In recent years, the artificial fishery aquaculture industry has been vigorously developed because fishery resources face severe decline due to over-fishing and deterioration of fishery environment.

When a plurality of aquatic animals are artificially cultured, the difference between the culture environment and the natural growth environment is faced, for example, the water temperature, dissolved oxygen and the like are changed compared with the natural growth environment, so that the culture success rate and the culture quality are influenced, meanwhile, the factors of the water temperature, dissolved oxygen and the like in the real culture environment are limited, if the culture density of the aquatic animals is improved, the conditions of water temperature rise, water quality deterioration, insufficient dissolved oxygen, frequent diseases and the like can occur, so the culture density of the aquatic animals is very limited, the culture area needs to be improved, and therefore, the traditional culture process needs higher culture equipment cost and labor cost. Meanwhile, the traditional breeding mode needs to replace breeding water manually at regular intervals, which wastes water resources and causes labor burden.

The runway type culture is a high-efficiency culture mode of circulating water in ponds, which is developed in recent years, and can limit aquatic animals in runways, make the flowing water continuously flow in the runways to bring oxygen, and filter excrement and residues through other equipment. The runway type aquaculture density is high, but excrement and urine and residues of pond water bodies outside runways are not thoroughly collected, so that the self-cleaning capacity of the pond is poor, the ecology of the water bodies in the pond is oppressed, the aquatic animals are not favorable for growth, the aquaculture tail water can not be recycled, the water consumption is large, the water waste is serious, and the aquaculture yield is not high. Research reports that in areas with developed aquaculture, aquaculture tail water becomes a main factor of water eutrophication, the aquaculture tail water contains nitrogen, phosphorus, organic matters and other substances which are nutrient substances required by plant growth, and the aquaculture tail water can be considered to be recycled for aquaculture because toxic and harmful substances are generally rarely introduced into aquaculture.
