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.
(seafood.vasep.com.vn) The US remains Vietnam’s largest single market for shrimp imports, accounting for 20% of Vietnam's total shrimp exports globally. As of October 15th, 2024, Vietnamese shrimp exports to the US reached nearly 600 million dollas, marking a 10% increase compared to the same period in 2023.
(seafood.vasep.com.vn) According to Vietnam Customs, pangasius exports to Canada reached over 1 million USD in the first half of October 2024, a 33% decrease compared to the same period last year. However, by October 15, 2024, total pangasius exports to Canada had reached 32 million USD, reflecting a 10% increase compared to the same period in 2023.

(seafood.vasep.com.vn) The Dong Thap Pangasius Festival 2024, themed 'Dong Thap Pangasius: Green Journey - Green Value', will take place on November 16-17 in Hong Ngu City.
The positive business momentum in the domestic seafood sector could last into the first half of 2025, according to experts.
(seafood.vasep.com.vn) In the first three quarters of 2024, brackish water shrimp production exceeded 1.1 million tons, with export revenue reaching $2.8 billion. The seafood industry has set a target of $4 billion for shrimp exports for the entire year.
While the price of 1 kg of shrimp hovers around 20 USD, the value of 1 kg of chitosan—extracted from shrimp—can soar to 500 USD. This highlights a significant challenge within the seafood processing industry.
(seafood.vasep.com.vn) By October, Vietnam's shrimp exports had generated nearly $3 billion, reflecting an increase of over 10% compared to the same period last year. Shrimp remains the leading commodity contributing to the export turnover of the entire seafood industry.
(seafood.vasep.com.vn) Sao Ta Foods Joint Stock Company (FIMEX VN - HoSE: FMC) concluded Q3/2024 with significant growth in revenue. Specifically, Sao Ta Food recorded revenue of VND 2,845 billion, a 58.6% increase year-on-year. The company's profit after tax reached VND 95 billion, up 6.2%.
VASEP's Seafood Export Report for the third quarter of 2024 provides a comprehensive overview of Vietnam's seafood export performance in the first nine months, with impressive results reaching $7.2 billion—an increase of 9% over the same period last year. In the third quarter alone, seafood exports grew by 15%, totaling $2.8 billion. This growth is attributed to a recovery in demand and prices in key markets such as the U.S. and China, as well as the competitive advantage of value-added products in markets like Japan and Australia.
