The base adopts a large-scale, industrialized, and modern flowing water farming mode. The water source is taken from the natural Yangtze River water, and the eel fry come from artificial seasonal natural fishing. During the breeding process, the water quality, temperature, and the growth status of the eels are monitored at any time. The generated wastewater also needs to be purified many times and tested to meet the standards before discharged. All the eels must also pass the tests of heavy metals, drug residues, microorganisms, etc. before they can be marketed.
