The study was conducted to interview 60 whiteleg shrimp farms in Duyen Hai and Cau Ngang districts, Tra Vinh province. The aims of this study were to investigate the drugs, chemical use and common diseases in cultured whiteleg shrimp (Litopenaeus vannamei). Results showed that white feces syndrome occurred in both of shrimp farming systems (earthen ponds and plastic-lined ponds) with the same ratio of 56.6%. Red body syndrome was recorded at the percentage rate of 40% in earthen ponds and 3.3% in plastic-lined ponds. Acute hepatopancreatic necrosis disease appeared differently in earth pond and plastic-lined ponds with ratios of 26.6% and 36.6%, respectively. The common antibiotics were cotrim (23.3%), amoxcillin (20%) and ciprofloxacin (13.3%). Most of the interviewd shrimp farmers applied probiotics in their shrimp ponds with such common microorganism species as Bacillus subtilis, B. licheniformis and B. megaterium. The obtained results showed the need to provide training to shrimp farmers to guarantee for the safety of aquatic products.
