An ecological pond for aquaculture

Abstract

The invention discloses an ecological pond used for aquaculture. The ecological pond comprises a plurality of filter ponds which are divided by a dam, wherein a water pushing device is arranged on the dam among the filter ponds; and a pond is arranged in one of the plurality of filter ponds. In comparison with a conventional mode, the ecological pond with the structure enables fish cultured in the pond to grow in flowing water with high dissolved oxygen all the time, so that the fish is high in growth speed, high in rate of survival, high in yield per unit and low in feed coefficient; and the ecological pond is liable to prevent and cure diseases, simple for production management, and convenient for capturing the fish. Meanwhile, the filter ponds achieve the effect of purifying water, so that water is recycled, and therefore, effects of saving water sources are achieved. The ecological pond is suitable for multi-variety and multi-specification breeding, so that the fish appears on the market in a balanced mode; the turnover of capitals is accelerated; and the production cost can be reduced by 35%. The greatest advantage of the technology is that 75% of fish metabolite and residual feed can be effectively collected, the virtuous circle of the fish pond is guaranteed, energy conservation and emission reduction are realized, and the environment is protected, thereby realizing low-carbon, high-efficiency and sustainable development of the aquaculture industry.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an ecological pond for aquaculture. 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. 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 Plan-2030 Fisheries Project initially proposed that the world's aquaculture production must increase by 100% in the next ...
