TOPGEN launches new black tiger shrimp, signs strategic partnership

On April 24 in Khánh Hòa and April 26 in Bạc Liêu, Topgen Vietnam organized a series of seminars to introduce a new generation of domesticated black tiger shrimp, while assessing its suitability for aquaculture models in Vietnam. The events also focused on discussing technical issues in seed production under changing weather conditions, particularly broodstock conditioning and hatchery processes.The program was attended by international experts from Topgen Thailand, more than 20 hatcheries in Khánh Hòa, along with representatives from fisheries and veterinary authorities, agricultural extension centers, and local shrimp farmers. According to Mr. Dang Quang Hao, the shrimp industry is currently facing multiple pressures, including climate variability, rising production costs, and unstable markets, which impact both hatchery and farming operations. “The seminar aims to bring stakeholders together to improve efficiency and stability in shrimp farming, with a focus on applying Topgen’s new domesticated shrimp line to enhance productivity and reduce risks,” he said.

 
 
At the event, Mr. Sukit presented Topgen’s genetic breeding program, which focuses on performance optimization across the entire production chain. Unlike wild-sourced shrimp, Topgen shrimp are selectively bred over generations to improve broodstock fertility, larval quality, and adaptability.
The shrimp demonstrate stable reproduction, high larval quality, strong disease resistance, and high survival rates. The BlackGEN genetic platform emphasizes heat tolerance, using heat shock protein (HSP) indicators and “Heat Shock Challenge” testing to select resilient shrimp lines.
  
 
Topgen also applies strict biosecurity measures, including ozone-treated water, ultrafiltration systems, PCR screening, and controlled nutrition, aiming to produce SPF-quality broodstock.
Field results show improved growth, survival, and productivity. For example, the TOPGEN MAX whiteleg shrimp line achieves strong reproductive output, growth rates of 0.30–0.35 g/day, survival rates up to 90%, and high yields under intensive farming conditions. A key highlight of the event was the strategic partnership signing between Topgen Vietnam and major Vietnamese hatcheries, aiming to supply next-generation domesticated broodstock for 2026–2027, with commitments on genetic quality and technical support. 
  
 
According to Mr. Tran Cong Binh, Topgen shrimp show comparable growth to traditional lines but offer higher survival and stress tolerance, especially under extreme heat and salinity conditions Participants emphasized that genetic standardization and stronger collaboration across the value chain—from breeding to farming—will help reduce risks, optimize costs, and improve overall efficiency and sustainability in Vietnam’s shrimp industry.
