Lightner and assistant staff scientist Linda Nunan created a rapid diagnostic test capable of detecting the genetic differences between the pathogenic and non-pathogenic versions of the common marine bacterium, Vibrio parahaemolyuticus, which causes the disease.
This method will enable specific detection of affected shrimp, currently only identified through the use of histology, which is time consuming and expensive.
A rapid polymerise chain reaction (PCR) test for the detection of this pathogen will be the first on the market and is critically needed by the shrimp producing industry.
To get the solution into the hands of shrimp farmers, Lightner is partnering with Tech Launch Arizona (TLA), the University of Arizona’s technology commercialization office.
Through TLA’s processes, the UA entered into a licensing agreement with GeneReach Biotechnology Corporation to commercialize the solution and make it available worldwide.
“In commercializing this technology, we’re creating the pathways to get it out to the people who need it as quickly and efficiently as possible,” said Doug Hockstad, director of Tech Transfer Arizona.
Grace Chang, CEO of GeneReach, said the products are expected to be launched in early 2014. Lightner is also ready to bring the solution to the world as soon as possible.
“Developing the diagnostic has been a complex process,” he said, “but now that we’ve got that done, I’m just delighted that we have a clearly defined way to get it out to the world to help solve the problem.”
EMS has been killing off the stocks of the world’s three largest shrimp producers; Thailand, China and Vietnam and in some places, production is down by nearly 50 percent from last year.
(seafood.vasep.com.vn) After a fairly strong upward trend in 2025, Vietnam’s clam exports entered 2026 with a mixed picture: strong growth at the beginning of the year, followed by a slowdown from March onward. According to Vietnam Customs data, Vietnam’s clam export turnover in the first four months of 2026 reached more than USD 38 million, up 2% compared to the same period in 2025.
(seafood.vasep.com.vn) Vietnam’s pangasius industry is facing new opportunities to expand its development space as many localities and businesses begin promoting marine farming models aimed at diversifying farming areas and adapting to climate change. However, for pangasius to truly “go offshore” and develop into a large-scale industry segment, significant challenges related to technology, broodstock, and markets still need to be addressed.
(seafood.vasep.com.vn) Vietnam’s tilapia exports in April 2026 reached USD 11 million, up 92% compared to the same period in 2025. This strong growth indicates that Vietnamese tilapia products are continuing to penetrate and expand rapidly in international markets. Cumulative export turnover in the first four months of 2026 reached USD 49 million, up 151% year-on-year.
(seafood.vasep.com) At VietShrimp Asia 2026, disease management trends in shrimp farming are shifting strongly from treatment-based approaches toward proactive prevention through environmental and pond ecosystem control.
(vasep.com.vn) After a period of strong growth, with export turnover reaching USD 38 million in Q1/2026 — up 174% year-on-year — the sector’s rapid expansion clearly reflects growing market opportunities.
(vasep.com.vn) In the first quarter of 2026, Vietnam’s pangasius exports to the ASEAN bloc reached USD 44 million, up 7% compared to the same period in 2025. After falling to the lowest level of the quarter at USD 9 million in February — reflecting the seasonal slowdown in orders after the festive period — exports recovered strongly to USD 18 million in March, the highest monthly value of the quarter. This development shows that import demand for pangasius in ASEAN remains relatively stable despite short-term fluctuations.
(seafood.vasep.com.vn) On May 11, 2026, the US National Oceanic and Atmospheric Administration (NOAA) announced a positive comparability finding for Vietnam’s swimming crab fisheries, along with those of Indonesia and Sri Lanka, under the Marine Mammal Protection Act (MMPA). With this decision, seafood and seafood products harvested from Vietnam’s swimming crab fisheries will continue to be eligible for import into the US market.
(seafood.vasep.com.vn) After a slowdown in 2025, Vietnam’s tuna exports to Germany showed more positive signs in the first quarter of 2026. However, the recovery remains uncertain as consumer demand in Germany is still cautious, while market competition is increasingly driven by pricing and supply stability.
(seafood.vasep.com.vn) After a sharp decline in 2025, Vietnam’s tuna exports to Israel are showing positive signs of recovery in the early months of 2026. According to Vietnam Customs data, export turnover to this market grew steadily month by month in Q1/2026, reaching nearly USD 10 million, up 33% compared to the same period in 2025. However, compared to Q1/2024, this level remains significantly lower, indicating that the recovery is still in its early stage following last year’s strong adjustment.
(seafood.vasep.com.vn) Entering 2026, the U.S. whitefish market has shown complex developments as global cod supply continues to tighten, while the U.S. trade environment becomes less stable. In this context, the U.S. market has had to become more flexible in sourcing alternative whitefish. However, relying heavily on Alaska pollock is not a long-term solution, as it is a strictly managed fishery with quotas and sustainability regulations, limiting any rapid increase in output to offset cod shortages.
