1. Water temperature: Prawns are tropical shrimp species. The suitable water temperature for growth is 16°C to 40°C, and the optimal temperature is 22°C to 32°C. In addition, the shrimp breeding cycle is 3-4 months, so the temperature of the place you choose to culture the shrimp must be suitable;
2. Salinity: Shrimp can be cultured in both seawater and freshwater. Needless to say, marine culture is simple. The key is freshwater aquaculture. If you are aquaculture in freshwater, you should pay attention to the desalination of shrimp seedlings. If you don’t have a desalination formula, try not to desalinize it yourself. The survival rate is very low. The most direct way is to go directly to the freshwater desalination nursery to buy desalinated shrimp seedlings;
3. pH value: The water quality of the selected breeding site can adjust the pH value (pH value), and the shrimp is most suitable for the range. 7.8-8.8 is better;
4. Dissolved oxygen: The dissolved oxygen in the bottom water is above 3 mg per liter, and the surface water is above 5 mg per liter.
5. Transparency: Transparency reflects the number of plankton and other microorganisms in the water. It is best to adjust the transparency of the shrimp breeding water to 30 to 40 centimeters. If it cannot be adjusted, try not to start breeding;
6. Ammonia nitrogen and nitrite Salt: should be controlled below 0.2 mg per liter;
7. Water circuit tee: Water quality testing can be determined based on points 1 to 6 above. The power supply must be a three-compartment 380-volt power supply, because most aerators and other electrical equipment use three-compartment power. The road should generally be 4 meters wide so that large trucks can fit in, making it easier to sell shrimp;
8. The selected shrimp pond should not have water accumulation or leakage: water accumulation and water leakage will cause long-term stress reactions in shrimps. , the shrimps don’t grow long at first, but then they die one after another;
9. The most important thing is: the public security environment must be good, otherwise there will be no need to discuss it! ! !
