Ultra-high-density industrial pond ecological breeding system and regulation method thereof

Abstract

The invention relates to an ultra-high-density industrial pond ecological breeding system and a regulation method thereof. According to the method, a breeding pond is divided into a main fish breeding area, a water treatment area and an accessory fish breeding area. Eating fishes are bred in the main fish breeding area, maximum fish carrying capacity is 120-160 kg / m<3>, the water treatment area is mainly used for biological purification treatment of breeding water, and filter feeding fishes are bred in the accessory fish breeding area. The breeding water is driven by an underwater plug-flow aeration device to enter the water treatment area for purification treatment from the main fish breeding area, is deep purified by the accessory fish breeding area and returns to the main fish breeding area, and the closed circulation process of the breeding water is finished. Effective microbial agents are fed, biochemical treatment of the breeding water is enhanced by a 'bacteria-algae-fish' symbiotic comprehensive regulation method, toxic and harmful substances in the water are removed, water eutrophication is prevented, and healthy breeding of the ultra-high-density pond is achieved. Breeding wastewater discharge is avoided, yield and quality are high, energy consumption is low, water and soil resources are protected and saved, and the method is a sustainable modern agricultural breeding and multiplication mode.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and relates to a high-density pond circulating water aquaculture technology method. Background technique [0002] China's aquaculture occupies an important position in the world. Since entering the 21st century, my country's aquaculture has continued to maintain a strong development trend and has become an important growth point of the large agricultural economy. In the past, most of the fishery production was extensive and small-scale pond farming. The farming facilities were simple, and the farmers lacked advanced farming concepts. They were highly dependent on the environment and resources, which not only affected the farming output and economic benefits, but also caused the loss of various resources. Waste and pollution of the environment. Water-saving, land-saving, and controllable industrialized fish farming is one of the development directions of the aquaculture industry, but the inve...

In the past, most of the fishery production was extensive and small-scale pond farming. The farming facilities were simple, and the farmers lacked advanced farming concepts. They were highly dependent on the environment and resources, which not only affected the farming output and economic benefits, but also caused the loss of various resources. waste and pollution of the environment

Water-saving, land-saving, and controllable production of industrialized fish farming is one of the development directions of the aquaculture industry, but the investment and operation costs are high, and the development is restricted
