In recent years, the production of eel in the world has shown a downward trend. The reason is mainly because the eel fry cannot be artificially propagated. Moreover, the number of eel fry caught in nature has fallen sharply. In the past many years. From Japan to China, the coastal freshwater rivers can catch a large number of eel fry. Today, due to changes in the natural environment and people's over-fishing. The eel fry becomes a very scarce variety. As a result, salmon are listed as endangered animals in the Pacific Rim countries. The scarcity is thus evident. In the future, you can see that the price of squid will soar. It will take a few years, and perhaps the squid will completely disappear from people's table.
Therefore. It is important to improve the success rate of salmon farming. The best way to improve the success rate of aquaculture is to use a factory-style method to stock the eel fry. Or from the beginning of seedlings to sales, the factory-based recirculating aquaculture model is adopted. Because of the farming process, the factory-circulated water mode can ensure that the water quality changes are minimal, which in turn greatly improves the living environment of the eel.
Farmed fish ponds at the start of construction:
The protein skimmer can separate solid suspensions of small particles in water:
In addition to separating the solid suspension, the protein separator has a significant oxygen-enhancing effect and is oxygenated against the biochemical pool.
Ultraviolet sterilizer effectively controls the concentration of bacterial virus in water:
drum filter are the primary equipment for filtering large particulate solids suspensions:
