Eel farming in China

China has now become the world's biggest exporter of eels breeding and are mainly distributed in fujian, guangdong, jiangxi, jiangsu, zhejiang and other places, all relevant professionals to reach hundreds of thousands of, to realize agriculture, increase farmers' income has played a positive role in promoting China's eel farming mainly has two modes: eel farming in cement ponds and eel farming in mud ponds

Eel farming in cement ponds

Cement pool breeding, as the name implies, is in indoor breeding, with cement to build out the size of the same specifications, water outlet, water inlet, sewage discharge and waste channel linked breeding pool. This kind of construction pool investment is larger, but it is also the safest, the most controllable breeding process.

Key points: Fine breeding mainly focuses on European eel and American eel

Eel farming in mud ponds

Earth pond fine breeding pond is a more traditional and convenient mode of eel breeding. The biggest difference with cement refined breeding is that it can not drain water, can only introduce new water from beginning to end, and can not discharge waste water. The mud at the bottom of the pond is used to digest the residual bait and excrement from eel farming, so the quality of feed is higher and antibiotics and harmful aquatic drugs are not allowed to be used. The cost of this model is 1/3 lower than that of cement pond, but it is affected by uncontrollable outdoor weather factors, such as the possibility of eels escaping in heavy rain, and extreme drought and water shortage.

Water sources for eel farming

Both cement pond intensive cultivation tank and soil pond cultivation use river water, groundwater, mountain spring and other water sources to carry out high-density cultivation. This cultivation mode uses large irrigation and large drainage, resulting in a large consumption of water resources, and the cultivation water quality and eel disease are susceptible to many factors such as climate and season. The newly issued environmental protection policies have put forward higher environmental requirements for the discharge and heating of tail water in eel cultivation, and the traditional intensive cultivation mode of cement pond has been subjected to increasing environmental supervision pressure.

Now have aquatic equipment research and development company, developed a factory in the circulating water ecological farming mode, use innovative ecological inside and outside the binary aquaculture water purification and treatment system, low energy affiliated facilities, clean and renewable energy and new environmental protection building materials, belongs to the advanced farming technology, concrete manifestation is:

1. Ecological recycling water. In terms of internal circulation, it can immediately discharge the residual bait, excrement and other contaminants from the aquaculture pond, and reuse the aquaculture pond water to ensure the stability and quality of the aquaculture pond water, thus reducing the discharge of the pond water, maintaining the stability of the aquaculture water quality, alleviating the stress of eel and reducing the occurrence of diseases. In the aspect of external circulation, the solid-liquid separation of aquaculture tail water and the separation and reuse of resources can effectively improve productivity efficiency. The separated fecal residue bait will enter the external circulation system through a special pipe for solid-liquid separation, and large particles of fecal waste solid and small particles liquid tail water will be separated by resource utilization. Larger particles waste solid processed into biological organic fertilizer for the use of local farming and crop, liquid particles through the tail water "ZhongYangShi integration" fish food symbiotic system, realize the water in the tail water, nitrogen, phosphorus and other nutrients recycling use, back to the aquaculture workshop for circulating water aquaculture, greatly reduce water consumption, saving water resources and protection of water ecology.

2. Clean energy utilization. Abandon the coal boiler heating mode, use air energy, geothermal heat pump and other clean energy heating mode, no emissions of pollutants, realize intelligent temperature control management, improve energy utilization efficiency, maintain the stable breeding environment.

3. Intelligent construction. The use of new building and thermal insulation materials, new pond structure, equipped with intelligent monitoring and control equipment, modular design, standardized construction, aquaculture, management system intelligent monitoring, automatic control, effectively reduce labor consumption.

4, the whole process is safe and controllable. The whole industrial chain project construction of the integrated development of the primary, secondary and tertiary industries of modern agriculture is adopted to implement standardization, informatization and systematic operation throughout the whole process of product production, which can be traced to the source and effectively guarantee food safety throughout the whole process.
