Shrimp breeding for resistance to Taura Syndrome Virus
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.

Broodstock center in India supports domestic shrimp-farming industry
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.

Thailand study: Performance trials generate important result
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.

Obstacles and opportunities in penaeid shrimp breeding
As economic benefits of selective penaeid shrimp breeding become more compelling, the shrimp industry will invest in breeding programs to produce genetically superior stocks.

Super-intensive RAS trial yields encouraging shrimp harvest at Oceanic Institute
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.

Shrimp copyright: Inbreeding strategies effective against copying of genetically improved shrimp
Shrimp breeders often protect their genetic investment by selling broodstock that will accumulate increasing levels of inbreeding in successive generations.

Research reveals inbreeding depression in Pacific white shrimp
Inbreeding depression, the loss of vigor among offspring when related individuals mate, can occur when intense selection is coupled with a narrow genetic base.

SPF-defined pathogen-free status of shrimp limited
Specific pathogen-free status depends on the presence or absence of specific pathogens. This status depends on the level of biosecurity for the shrimp.

Selectively bred shrimp survive varied TSV exposure
A 14-day study evaluated mortalities related to TSV exposure, as broodstock resistant to an “old” strain succumbed to a “new” Belize strain of the virus.

Sexual growth dimorphism in penaeid shrimp
Sexual growth dimorphism occurs in cultured aquatic species like tilapia, catfish and salmon, and has also been reported for cultured crustaceans.
