The project produces specific-pathogen-free broodstock with good reproductive performance, fast growth and high survival. More than 60 hatcheries in India have received broodstock from the program.

Basic components of biosecurity include knowledge of diseases, adequate detection methods and the use of “clean” shrimp stocks.
In response to Taura Syndrome Virus outbreaks, the U.S. Marine Shrimp Farming Program initiated a selective-breeding program to improve resistance in Pacific white shrimp.
In research involving white shrimp siblings raised in ponds in Thailand and in raceways in Hawaii, shrimp growth can be improved after one generation of selection, even with a modest investment.
As economic benefits of selective penaeid shrimp breeding become more compelling, the shrimp industry will invest in breeding programs to produce genetically superior stocks.
A super-intensive RAS grow-out trial produced 5.7 kg of shrimp per square meter in 14 weeks using minimal water volume and only 0.34 percent daily water exchange.
Kona line reference shrimp contribute to research by providing test stocks that are consistently and predictably susceptible to Taura Syndrome Virus.
Inbreeding depression, the loss of vigor among offspring when related individuals mate, can occur when intense selection is coupled with a narrow genetic base.
Specific pathogen-free status depends on the presence or absence of specific pathogens. This status depends on the level of biosecurity for the shrimp.
