Microsatellite Polymorphism and the Population Structure of the Black Tiger Shrimp (Penaeus monodon) in Thailand.

Genetic variation and differentiation of Thai Penaeus monodon from five geographic locations (Chumphon, Trad, Phangnga, Satun, and Trang) were investigated using five microsatellite loci (CUPmo18, Di25, Di27, CSCUPmo1, and CSCUPmo2). The number of alleles across the five loci ranged from 19 to 30, and heterozygosities ranged from 0.49 to 0.
