What should novices pay attention to when cultivating stone fish? What are the culture techniques of rock carp?

1. The pond shall meet the requirements of sufficient water source, flat bottom and convenient water injection and drainage. The main culture pond should be close to the spawning pond and hatchery, with an area of 1-5 mu and a water depth of 1.2- 1.5 m, and the bottom of the pond should have silt. In addition, while meeting the pond conditions, pond equipment, such as aerators, should also be prepared.

2. The whole pond can be pulped with quicklime100-150kg/mu and then disinfected thoroughly. After the disinfection work is completed, the next step is fertilization, which can artificially sprinkle 40-50 kg/mu of fermented chicken manure to cultivate zooplankton and benthos in the water.

3. Pay attention to the selection of high-quality fry when stocking. Before stocking, the fry should be quarantined and soaked in 3% salt solution 15 minutes. Generally, the seedlings are released in early May, and the stocking density is: 1.5-2.5kg rock carp 1200- 1800 fish/hectare.
