Abstract
Genetic variability of wild and cultured black tiger shrimp populations in Thailand was studied by the microsatellite DNA technique. In wild populations from the Gulf of Thailand, South Thailand, and South Myanmar, high genetic variability was detected. Mendelian inheritances were evaluated in juveniles from 4 farms. In three of the farms, more than 4 genotypes were identified, indicating that the farms did not use single parental line. Genetic approaches are required to achieve stable production rates in black tiger shrimp cultures.
