Embodiment Construction

[0027] like figure 1 and figure 2 As shown, the present invention has an ecological circulation freshwater culture method. First, the water tank for supplying fresh water and the geothermal well for supplying geothermal water are connected to the water distribution pool through pipelines, and the fresh water and geothermal water are adjusted to be suitable for breeding in the water distribution pool. The temperature of the water distribution pool is connected with the cultivation greenhouse through pipelines, and supplies water to the cultivation greenhouse; the cultivation greenhouse includes several cultivation ponds, and the several cultivation ponds are arranged in sequence from left to right to form a cultivation pond group, and the water outlet of the distribution pond The main water supply pipeline is installed, and the water supply is completed by connecting the branch water pipes drawn from the main water supply pipeline with each culture pond; the center of the bott...

Abstract

The invention provides an ecological cycling freshwater aquaculture method. The method comprises: preparing a culture water source, supplying water to culture ponds, filtering water, and treating sewage. The plurality of culture ponds are arranged from left to right in sequence to form a culture pond group. The culture ponds in the culture pond group are connected in parallel, and form a recirculating aquaculture system with a filter tank, a treating pond, a settling pond, a biological package, an aeration tank, and a sterilization pond. Using the ecological cycling freshwater aquaculture method, water of the whole system forms virtuous cycle, and is suitable for growth of freshwater fishes and shrimps, and zero discharge of aquaculture wastewater is realized, and water resource is saved. The ecological cycling freshwater aquaculture method has obvious ecological environment benefits, and meets the sustainable development strategy of the country.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an ecological cycle freshwater aquaculture method. Background technique [0002] At present, my country is in the situation of saving resources and protecting the environment, and vigorously promotes ecological farming methods. Compared with the complex ecosystems of natural rivers and lakes, the traditional pond farming ecological environment is relatively fragile and lacks sustainable self-purification ability. Can not meet the needs of social development, there are still many technical problems to be solved. Due to the constraints of many conditions, the traditional breeding method has an unreasonable structure. The feeding, metabolism and survival activities of fish and shrimp are all in the same pond water body. The continuous fertilization, feeding and metabolism of fish and shrimp make the limited water body gradually lose its vitality. To restore and resto...
