Shrimp farming technology is the key to water transfer during the breeding cycle. The quality of water determines the success or failure of a shrimp farm. Now introduce four specific physical and chemical indicators:
1. PH value of the water body: The ph value of the aquaculture water in the previous period is generally between 8.0 and 8.5. At this stage, PH is not adjusted. In the middle and later stages of cultivation, ponds with too low PH are conditioned with quicklime, and dolomite is used as the bottom for the acidic soil (mangrove area). For ph ponds that are too high, they are gradually regulated with live bacteria such as organic acids and lactic acid bacteria (EM bacteria).
2. Total Alkalinity: The total alkalinity of the pond is between 80 and 120 (German degrees) during the whole breeding cycle. The use of dolomite powder to adjust the total alkalinity is best.
3. Total hardness: For shrimp aquaculture, it is relatively moderate at 80-120 (German degree). In general, the total hardness is too low plus calcium dichloride regulation, and the total hardness is too high to be adjusted with baking soda.
4. Salinity: The ability of disease resistance of shrimp is enhanced under proper salinity. The adjustment of salinity can be easily solved by changing the water, but the principle of changing the total amount of water is that the amount of water per day accounts for less than one-third of the total amount of pond water.
