High profit
Deputy Director of the Provincial Agricultural Extension Center Phan Van Phuong said that the model was implemented in An Binh village, Hieu Giang commune on an area of 0.2 hectares, raising 40,000 giant freshwater prawns, equivalent to a density of 20 prawns/m2. The model uses specialized industrial feed for shrimp with a protein content of over 39%. Of which, the Provincial Agricultural Extension Center supports 50% of shrimp, industrial feed and probiotics with a total value of more than 76 million VND, the remaining amount is contributed by the farming households. During the implementation of the model, the Provincial Agricultural Extension Center sent technical staff to regularly monitor and check the growth of the shrimp to take timely measures.
Mr. Ho Van Tho, the household implementing the model, said that in this area, his family used to raise grass carp, silver carp, common carp, tilapia, etc., but the economic efficiency was not high, and there were many risks due to diseases and weather. In 2025, he was selected by the Provincial Agricultural Extension Center to implement the model of raising giant freshwater prawns in ponds, so he repaired, reinforced, cleaned the pond, and installed a water fan system according to the instructions of technical staff.

After 6 months of farming, the shrimp reached an average size of 20 shrimp/kg, the survival rate was over 66%, and the harvest yield was about 1.32 tons. With an average selling price of about 250,000 VND/kg, after deducting expenses, the model is estimated to bring in an income of over 80 million VND. “The giant freshwater prawn itself is a healthy species, highly adaptable, so it rarely gets sick and has a low risk rate. The farming time is only 6 months before harvest, shorter than traditional fish which have a farming time of up to 10-12 months, but the economic efficiency is much better,” Mr. Tho affirmed.
Easy to replicate
Sharing his experience in the farming process, Mr. Tho said that the first requirement for successful farming of giant freshwater prawns is clean water, so farmers need to pay attention to hygiene and water treatment before taking it into the pond. In addition, choosing the right breed is equally important. Currently, giant freshwater prawns must be imported from other provinces, so shrimp farmers need to research and choose a reputable breed supplier to ensure quality.
During the farming process, environmental factors such as pH and alkalinity in the pond must be measured daily to ensure they are within the appropriate range for shrimp growth. From the second month onwards, periodically change 30% - 40% of the water in the pond combined with probiotics to help clean the pond water environment and stimulate shrimp molting. At the same time, add digestive enzymes, vitamins, and minerals mixed into the feed and apply directly to the pond to increase the shrimp's resistance. Mr. Tho also noted that because giant freshwater prawns have the characteristic of eating each other, especially when they molt, to increase the survival rate of shrimp, farmers need to create a substrate with tree branches and coconut leaves, planted in clusters in the pond for shrimp to hide when molting.
According to Deputy Director of the Provincial Agricultural Extension Center Phan Van Phuong, through the model, it can be affirmed that giant freshwater prawns adapt very well to local climate, weather and soil conditions. Especially during the time of implementing the model, the weather fluctuated, changing seasons continuously, greatly affecting agricultural production, but giant freshwater prawns still grew well, with a high survival rate.
However, to achieve high productivity and yield, farmers need to understand the biological characteristics of giant freshwater prawns; choose juveniles with clear origins, uniform size, bright colors; should not stock at too high density, preferably 20 shrimp/m2 or less; use feed and manage feed properly. In particular, it is necessary to pay attention to pond renovation, water treatment... according to technical procedures.
According to Mr. Phuong, compared to traditional freshwater farming, the cost of raising giant freshwater prawns is quite high. For example, with the model implemented by the unit, the investment level for a crop with an area of 0.2 ha is nearly 250 million VND. Although the investment cost is large, after nearly 6 months of farming, the expected profit from the model is over 80 million VND, equivalent to 400 million VND/ha. This is a quite high income level compared to other traditional freshwater farming subjects.
“On this basis, the Provincial Agricultural Extension Center continues to deploy training courses and information and propaganda to replicate this giant freshwater prawn farming model in Quang Tri ,” Mr. Phuong emphasized.
