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.
