Genetic heterogeneity of the giant tiger shrimp (Penaeus monodon) in Thailand revealed by RAPD and mitochondrial DNA RFLP analyses.

Genetic diversity of the giant tiger shrimp (Penaeus monodon) collected from 5 areas, Chumphon and Trat (Gulf of Thailand), and Phangnga, Satun, and Trang (Andaman Sea), was examined by randomly amplified polymorphic DNA (RAPD) and mitochondrial DNA (16S ribosomal DNA and an intergenic COI-COII) polymorphism. A total of 53 polymorphic fragments from UBC299, UBC273, and UBC268 was consistently scored across all samples. From the respective primers 26, 32, and 30 genotypes were generated.
