Description
Technical Field
The invention relates to the technical field of ecological breeding, in particular to a closed ecological fish farming system and a fish farming method thereof.
Background
Modern industrial aquaculture often adopts facility aquaculture, and is characterized by high-density aquaculture, circulating water aquaculture and ecological technology aquaculture. The industrial cultivation mode is to put single-variety fishes with similar specifications in the same cultivation container, and adopts feed for standardized high-density cultivation. The fish continuously consumes oxygen and exhales carbon dioxide during growth, the feed is digested and the feces are discharged, and the residual feed can be continuously rotted and deteriorated in the water body, which can affect the water quality, so that the oxygen in the container is continuously increased, and the culture water is continuously circulated and purified to keep the water quality fresh.
In the past, the industrial cultivation mode generally has the effect of timely treating the fish-farming wastewater, so as to avoid the environment pollution caused by excessive discharge into the environment. The waste water (containing fish manure and ammonia nitrogen) for fish culture contains fertilizer required by plant growth, combines the fish culture process with the water planting process, collects and utilizes the waste water, and can form a closed circulation system for water resources. Through the interaction of cultivation and planting, the production efficiency of cultivation and planting is improved, resources are reasonably utilized, and the realization of a modern agriculture mode of ecological organic is an important development direction at present. The production system is generally an open system, air oxygenation (Roots blower oxygenation) is generally adopted, and the dissolved oxygen amount can reach 5-8mg/L. This is not optimal for high density farming. In recent years, research shows that if pure oxygen oxygenation is adopted, the growth condition of fish under the condition of high-density cultivation can be greatly improved, and the growth speed and quality are obviously improved.
However, the cost of oxygen enrichment by pure oxygen is high, and if an open container is continuously used, high-purity oxygen can easily escape from the water surface to the air, so that great oxygen waste is caused.
On the other hand, the carbon dioxide exhaled by the fishes has further utilization value, and the carbon dioxide concentration in the cultivation workshop is too high due to the loss of the carbon dioxide in the cultivation workshop, so that the physical health of workers is endangered. In the production system of industrial fish and vegetable circulation, carbon dioxide is a gas fertilizer necessary for photosynthesis of hydroponic vegetables, and in order to maintain a good growth rate of plants, a sufficient concentration of carbon dioxide gas in the air must be maintained in hydroponic plant units.
The invention adopts a sealable device, waste gas (mainly oxygen and carbon dioxide) in the cultivation container is collected and separated by the gas separation device, the oxygen flows back to the cultivation unit for continuous use, and the carbon dioxide is conveyed to the hydroponic plant unit for plant growth.
