Why is aquaculture cage widely used

Cage culture originated in Cambodia and other Southeast Asian countries in the late 19th century, and then spread to all over the world. In the 1970s, cage culture began in China. Due to the characteristics of low investment, high yield, maneuverability and quick effect, cage culture has developed vigorously in lakes and reservoirs all over the country in a short period of several decades.

Why is aquaculture cage widely used

1. It has the advantages of short feeding period, convenient management, flexible and easy operation. The net cage can be moved at any time according to the change of water environment conditions. The net height will not be affected in case of waterlogging and flood. The net position will not be damaged in case of drought. It can achieve the purpose of high and stable yield in drought and waterlogging.

2. It has strong adaptability and is easy to be popularized. The area of water area occupied by cage culture is small. As long as there is a certain water level and flow rate, it can be raised in rural areas, factories and mines.

3. Cage culture can make full use of water body and erbium material organisms, carry out polyculture, close cultivation, high survival rate and achieve the goal of high yield.

4. It can save the land and labor needed for fish pond excavation, and the effect is quick after investment. Generally, the whole cost can be recovered in the current year, while the net cage can be used continuously for 2-3 years under normal circumstances.

5. It's easy to catch. When harvesting, special fishing tools are not required. They can be put on the market at one time. They can also be caught in batches according to the market demand. It is convenient for transportation and storage of live fish. It is conducive to market regulation. People call it "live fish body" on water.
