Many farmers do not know how to improve the survival rate in the process of farming, and they are afraid of raising the cost. The benefits of industrial recirculating aquaculture lie in improving survival rate, reducing cost and selecting the best equipment. For those who have experience in aquaculture, a standard industrial recirculating aquaculture system is the preferred system.

Several precautions that can greatly improve the survival rate of perch fry in California bass industry are bound to be important:

1. Keep constant temperature: For the seedling farm, keep a certain temperature, suitable for stable breeding environment, the temperature of fish can be more stable. In the equipment temperature of the four seasons cycle, the temperature of fish directly affects the concentration. In general, the factory recirculating aquaculture fish pond chooses direct pumping, and the temperature should not exceed 40 C.

2. Control of pathogens: Bass culture generally requires high culture density, effective control of basic pathogens and water quality is necessary. This is the environmental protection problem that should be paid attention to in the early stage. Effective removal of soluble suspended contaminants such as protein.

3. The new product fan of CP compound degassing sterilizer keeps PH stable: acidity and alkalinity also play an essential part in fishery culture. Usually, we use water quality meters to measure PH, salt solubility and temperature. Only when the test is correct can the seedling be released.

4. Installing a small circulating pump in the pond can make the water flow, which is beneficial to the feeding of the fry during the training. Because the food is dynamic under the action of the water flow, California bass likes to eat live bait, and uses the water flow to stimulate the feeding of small fish. At present, domestication has become a common method in some ponds.
