On average, the water is changed every four days, and aeration machines are regularly used to improve aeration and change the water quality. Photo: TP

In the first farming season, the survival rate of crabs reached over 55%, yielding 850 kg of crabs, generating revenue of 350 million VND, and a profit of over 100 million VND after deducting expenses. Photo: TP

Based on the highly effective and stable commercial crab farming model, which is less costly than whiteleg shrimp farming, Mr. Nhân plans to expand the area to 1,000 square meters in the near future.²Photo: TP
