To provide background on the genetics of cultured Nile tilapia (Oreochromis niloticus) strains and basic information for breeding, we surveyed five Nile tilapia strains (Sudan, Taiwan, GIFT, SupermaleⅠand Supermale Ⅱ) using 19 microsatellite loci to estimate the genetic variation. A total of 113 alleles were detected. Mean expected heterozygosity (He) ranged between 0.578 and 0.692, and mean polymorphism information content (PIC) ranged between 0.473 and 0.628, indicating that these five Nile tilapia strains were genetically diverse. Of the five strains, the supermaleⅠhad less genetic variation compared with other strains.
