Development of white shrimp seeds resistant to infectious diseases in South Korea

Tridge summary

The National Institute of Fisheries Science in Korea has successfully developed a selective breeding program for whiteleg shrimp that are resistant to acute hepatopancreatic necrosis disease (AHPND), a major infectious threat to shrimp. This initiative follows a severe outbreak last year that slashed shrimp production by 30%. By using surviving shrimp as breeding stock, the West Sea Fisheries Research Institute produced new seeds that demonstrated a remarkable reduction in mortality rate to 4%, compared to 98% in the control group. This breakthrough represents a significant step forward in creating disease-resistant shrimp and will aid future selective breeding research efforts.

The National Institute of Fisheries Science announced on the 6th that it has established a selective breeding foundation for developing whiteleg shrimp with strong resistance to acute hepatopancreatic necrosis (AHPND), an infectious disease. AHPND is a Class 1 legal infectious disease of aquatic organisms, causing mass mortality and is known to be particularly fatal to young shrimp. Last year, the disease broke out in domestic whiteleg shrimp farms, and shrimp farming production decreased by about 30% compared to 2022. Accordingly, the West Sea Fisheries Research Institute of the National Institute of Fisheries Science secured whiteleg shrimp that survived the bacterial disease outbreak last year as mothers, produced seeds, and artificially infected them with pathogenic bacteria to verify the disease resistance of these seeds and investigated their survival rate. As a result of the investigation, it was confirmed that the seeds developed by the West Sea Fisheries Research ...
