Water push and oxygenation device for pond internal circulation flowing water culture

Abstract

The invention discloses a water push and oxygenation device for pond internal circulation flowing water culture. the water push and oxygenation device comprises an oxygenation machine which is connected with multiple oxygenation pipes through pipelines; the oxygenation pipes are provided with multiple holes for pushing water and generating oxygenation; the multiple oxygenation pipes are arranged side by side; the oxygenation pipes are welded with a fixing support. The device of the invention is suitable for culture of multi-kinds and multi-sizes; equalized sale is achieved and capital turnover is accelerated; the production cost can be reduced by 35%; 75% fish metabolite and residual forage can be effectively collected so that virtuous circle of the pond is guaranteed. The water push and oxygenation device for pond internal circulation flowing water culture is used for culturing fish with flowing water; air is used for lifting water and water pushing is more efficient; the cost is lower and there is no need of maintenance; water lift by air can effectively realize water push and oxygenation; flowing water passing through the pond can improve water quality and flush excrement of fish to downstream so as to collect and clear the excrement; floating and sunken solid body can be removed.

Description

technical field [0001] The invention belongs to the technical field of fish farming, and in particular relates to a water pushing and aeration device for circulating water farming in a pond. Background technique [0002] As the world population continues to increase, water resources will soon become a limiting factor for many industries, the nutritional cost of food production will further increase, the demand for high-quality aquatic products in Southeast Asian countries will increase significantly, and the fishing industry will maintain the status quo Or a downward trend, farmed aquatic products will occupy the main market. At the same time, the cost of water for agriculture, especially aquaculture, increases and the pressure on the environment increases. [0003] The biggest challenge of agricultural production in the 21st century is to use less resources to produce 3 times more products. The World Bank's Global Fisheries Program - 2030 Fisheries Project initially propo...
