In December 2013, a group of Thai and Taiwanese scientists released information on the primers and PCR protocols to bacteria causing this disease responsible of extensive damage to both domestic and international shrimp industries.
Despite the success attained with these protocols, named AP1 and AP2, the Thai research team continued to study this disease and make improvement on the detection technique.
The National Center for Genetic Engineering and Biotechnology (BIOTEC) informed that on 18 June, at the 6th International Shrimp Industry Development Forum at Zhanjiang Guangdong, China, the research team released information on a new and improved PCR method, called AP3 method.
This method is based on the gene sequence of a protein discovered in a sub-fraction of cell-free culture broth from isolates of Vibrio parahaemolyticus that cause AHPND, but not from V. parahaemolyticus or other bacteria that do not cause AHPND.
This cell-free preparation caused the typical signs of acute AHPND (massive sloughing of hepatopancreatic tubule epithelial cells) when administered to shrimp by reverse gavage. Primer (AP3) was designed to amplify the gene sequence of one small protein from this toxic sub-fraction.
According to BIOTEC, the AP3 method gave 100 per cent sensitivity, specificity, positive predictive value and negative predictive value for the detection of AHPND bacteria using 98 bacterial isolates characterized by bioassay as AHPND and non-AHPND bacteria.
The AP3 method was developed by a consortium of scientists from Mahidol University, Aquatic Animal Health Research Center of Charoen Pokphand Company and BIOTEC.

Patrols, monitoring of marine fishing activities, and handling of violations have been prioritized by competent forces, significantly reducing nearshore fishing infringements.
(seafood.vasep.com.vn) According to statistics from Vietnam Customs, Vietnam’s tuna exports to Israel in the first nine months of 2025 reached just over USD 27 million, down as much as 49% compared to the same period in 2024. This is a steep and prolonged decline for many consecutive months, reflecting changes in import demand as well as shifts in the supply structure of this market.
(seafood.vasep.com.vn) The first 700 tons of Vietnamese tilapia ordered and imported by JBS Group will initially be distributed through supermarket chains, the Horeca network and JBS’s product showrooms in Brazil.
(seafood.vasep.com.vn) In October 2025, Vietnam’s pangasius exports hit $217 million, representing an 8% increase compared to the same month in 2024. For the first 10 months of the year, total export value has surpassed $1.8 billion, up 9% year-on-year. This growth demonstrates clear positive momentum for the pangasius industry, despite continued declines in certain markets.
In recent days, the Central provinces of Vietnam have been suffering from historic flooding, with prolonged heavy rains, landslides, flash floods, and deep inundation causing extremely serious impacts on tens of thousands of households, as well as many VASEP member exporters located in the region. With the spirit of mutual support and solidarity, and in order to promptly assist residents and member exporters in the affected areas to stabilize their lives and restore production activities, VASEP calls on all seafood exporters, organizations, and individuals to extend supports to the people and member exporters in the flood-hit areas. We urge timely and practical material and spiritual contributions to help member exporters and local communities in the severely affected provinces overcome this difficult period.
(seafood.vasep.com.vn) In the final days of October 2025, Vietnam’s domestic raw shrimp market remained generally stable, though slight adjustments were recorded in several sizes across key farming regions.
(seafood.vasep.com.vn) Vietnam’s shrimp exports reached USD 498 million in October 2025, up 26% from the same period last year. This is one of the highest monthly revenues since the beginning of the year, reflecting solid demand in major markets and faster shipment schedules by exporters. From January to October, shrimp export value reached USD 3.9 billion, up 22% compared to the same period in 2024.
(seafood.vasep.com.vn) On October 31, 2025, the US Court of International Trade (CIT) officially issued an order to suspend the case filed by the National Fisheries Institute (NFI), the National Restaurant Association (NRA), and several US seafood companies against the US Government concerning the implementation of the Marine Mammal Protection Act (MMPA).
(seafood.vasep.com.vn) An Giang’s fisheries sector has maintained stable growth momentum during the first nine months of 2025, making an important contribution to the province’s socio-economic development. Despite facing numerous challenges, the province is implementing various measures to enhance production efficiency, expand markets, and promote sustainable fisheries development toward deeper integration into the global economy.
(seafood.vasep.com.vn) Vietnam’s pangasius export value in September 2025 reached USD 181 million, up 5% compared to the same period in 2024. The overall trend for the pangasius industry remains positive, with total exports in the first nine months of 2025 reaching nearly USD 1.6 billion, an increase of 9% year-on-year.
