Tim Fregel, a researcher and adviser at the National Centre for Genetic Engineering and Biotechnology (Biotec), said the breakthrough was due to cooperation between Thai and Taiwanese researchers.
The test can detect the fatal AHPND bacteria in shrimps within three hours, a huge improvement on the current method which takes around three weeks.
Prof Fregel said the new test for AHPND bacteria decodes DNA collected from samples of sediment, shrimp food or shrimp tissue.
A comparison is then made to see if the DNA sequence matches that of the AHPND bacteria.
The current method not only takes longer, but is more complicated. It starts with collecting shrimp bacteria, cultivating them and releasing them to the shrimps, then waiting to see if they die.
If the shrimps die, an outbreak of AHPND bacteria can be confirmed.
"The longer we take to confirm an outbreak, the bigger the loss for the farmer, as they can't take preventive measures. The rapid test is both a precaution and a prevention against outbreaks," he said.
Since the EMS outbreak in 2012, Thai shrimp farming has halved in productivity, not due to shrimps dying, but because farmers cut investments to prevent losses.
EMS spread from China in 2009 to Vietnam by 2010, to Malaysia by 2011 and to Thailand by 2012. Efforts to control the spread of AHPND were hampered by the lack of specific and rapid detection methods.
The rapid test is 99% accurate so far. More research and development is needed before it is 100% accurate, Prof Fregel said.
The research team has been working on the test since 2011 with support from the Department of Public Health at Mahidol University, the Aquaculture Business Research Centre, the faculty of fisheries at Kasetsart University and Burapha University, and shrimp farmer clubs in the South.
(seafood.vasep.com.vn) With a focus on sustainable development, high-tech application, and climate change adaptation, An Giang Province aims to maintain its brackish water shrimp production in 2026 at a level equivalent to the previous year. Specifically, output is projected to reach over 155,510 tons, serving both domestic consumption and export processing, thereby sustaining the fisheries sector’s key role in the local economic structure.
(seafood.vasep.com.vn) In the Mekong Delta, key pangasius farming provinces such as An Giang, Dong Thap, and Can Tho are accelerating the transition toward a circular economy model, contributing to higher product value and reduced environmental impact. Instead of focusing solely on farming and processing, the pangasius value chain is increasingly utilizing by-products and waste streams to generate added value.
(vasep.com.vn) Vietnam’s scallop exports are entering a phase of impressive growth, as the global market undergoes significant restructuring. In 2025, scallop export value reached nearly USD 66 million, up 49% from USD 44 million in 2024. This upward momentum has continued and accelerated into early 2026, with exports totaling USD 18.1 million in the first two months alone—an increase of 166% year-on-year. This represents an exceptionally high growth rate, reflecting the rapid expansion of a relatively new product segment within Vietnam’s mollusk export portfolio.
(seafood.vasep.com.vn) – On March 19, at the Government Headquarters, Prime Minister Pham Minh Chinh held a meeting with the European Commission (EC) inspection delegation on combating illegal, unreported and unregulated (IUU) fishing, led by Mr. Fernando Andresen Guimaraes, Head of Unit at the Directorate-General for Maritime Affairs and Fisheries (DG MARE).
(vasep.com.vn) Australia is emerging as one of the most stable and promising growth markets for Vietnamese shrimp. Amid global trade disruptions driven by geopolitical tensions—particularly conflicts in the Middle East—strengthening and expanding into stable markets like Australia has become increasingly important for Vietnam’s shrimp industry.
(seafood.vasep.com.vn) In the first two months of 2026, Vietnam’s squid and octopus exports reached over USD 111 million, up 23% compared to the same period in 2025. This result indicates a positive start for the sector, reflecting early signs of demand recovery in multiple markets from the beginning of the year.
(seafood.vasep.com.vn) In the first two months of 2026, Vietnam’s fisheries sector maintained positive growth momentum, with shrimp output exceeding 132 thousand tons. This result contributed to a strong increase in seafood export turnover, despite ongoing volatility in the global economy.
(seafood.vasep.com.vn) Vietnam’s tilapia exports maintained strong growth momentum in February 2026, with many markets recording sharp increases compared to the same period last year. In February alone, export value reached USD 8.4 million, up 148% year-on-year. Cumulatively, in the first two months of 2026, total tilapia export turnover hit USD 23 million, soaring 242% compared to the same period in 2025.
(seafood.vasep.com.vn) In global seafood trade, sensory evaluation is increasingly becoming one of the key “technical barriers” in many importing markets-especially the United States. Issues such as filth, and signs of decomposition/spoilage are often detected through sensory evaluation methods and remain common reasons for seafood import alerts, detentions, or shipment rejections.
Shrimp has been the most important export product of Vietnam’s seafood industry for many years, typically accounting for 35–45% of the country’s total seafood export value. With a well-developed farming, processing, and export system, Vietnam has become one of the world’s leading shrimp exporters.
