When it is hot or raining for a long time, it is necessary to open the fan 24/7 to avoid white feces, shrimps are easily shocked and bent.

– Maintain stable water color, NH3, H2S parameters at allowable levels and absolutely do not use products derived from plant protection drugs to treat water.

– Unpolluted water source, pH from 8.0-8.3, salinity from 10-25%.

Summary :

This process is highly effective for farming areas with separate supply and drainage channels to ensure sufficient supply of clean water for stocking needs, and to limit disease outbreaks. Hopefully through this article, all farmers and households will have more white leg shrimp farming experience effective.
