Scientific water quality management and disease prevention are indispensable for whiteleg shrimp (Litopenaeus vannamei) farming

The whiteleg shrimp (Litopenaeus vannamei) is native to the Pacific coast of the Americas and is one of the world's major farmed shrimp species. It is characterized by fast growth, strong adaptability and a relatively high meat yield; after desalination treatment, the fry can even be farmed in low-salinity water or even freshwater, so it is widely distributed in both coastal and inland areas of China.

In terms of farming methods, common models include traditional earthen pond farming, high-level pond farming and industrialized recirculating aquaculture. In recent years, the concept of ecological farming with low drug residues and water conservation has also attracted growing attention, and some regions have begun experimenting with farming methods that reduce water exchange and use little or no medication. Farmers can choose a suitable model according to local water sources, climate and financial conditions.

Water quality management is a key part of farming success. On a daily basis, attention needs to be paid to indicators such as dissolved oxygen, ammonia nitrogen, nitrite and pH; aeration equipment should be operated reasonably, water should be exchanged or beneficial bacteria supplemented at appropriate times, and the water body should be kept stable to reduce stress reactions in the shrimp.

For feeding, artificial compound feed is generally the mainstay, following the principle of small amounts given frequently, with the feeding amount adjusted flexibly according to weather, water quality and the shrimp's feeding situation, so as to avoid leftover feed spoiling the water quality.

Disease prevention and control should not be neglected either. In the middle and late stages of farming, priority should be given to preventing problems such as Vibrio infection and white spot syndrome, and prevention should be done well in areas including fry selection, water disinfection and daily pond patrol monitoring. Overall, whiteleg shrimp farming has a relatively short cycle and high market acceptance, making it an important choice for many aquaculture farmers, but to farm it well still requires meticulous daily management and scientific farming concepts.
