Besides the fact that spot prawns are the same as ordinary shrimp, their astaxanthin content is about 20% higher than that of ordinary shrimp, which makes them more expensive during the Chinese New Year, and astaxanthin is one of the strongest antioxidants.

By itself, it significantly enhances shrimp survival and spawning rates, as well as resistance to harsh external environments. Similarly, human and animal consumption of shrimp meat high in astaxanthin can significantly improve atherosclerosis and other disorders.

Salinity and temperature of spot prawns:

Water temperature control at 27-29 ° C, seawater salinity of 10-20, ph value of 7.8-8.5.

Spot prawns optimal salinity of 12 ‰, and shrimp fry in the early cultivation of salinity in the 30 ‰ or so, so just stocking of the pool salinity should be similar to the pond with shrimp fry pools, stocking can be gradually add water to make the Salinity down to the appropriate range. Therefore, a good water source and perfect drainage system is essential. Shrimp farming places have freshwater sources (including groundwater) and no large river outlet is best.

Spotted shrimp can tolerate water temperatures in the 10 ~ 35 ℃ around the optimal temperature of 25 ~ 30 ℃. Raising period if the water temperature changes too much, short-term groundwater can be extracted to fill, such as long-term water temperature at about 20 ℃ and not too windy, you can lower the water level, the use of daylight energy to increase the temperature; water temperature is too high can raise the water level or inject groundwater.
