The genetic structure data of Nile tilapia from SSR assay were compared with that from AFLP. The ratio of polymorphic sites percentage from SSR to AFLP averaged 1.683 17, the average ratio of population specific Fst indices was 1.249 87, and the ratio of gene diversity in group averaged 1.676 60, respectively in 5 populations. The ratio of genetic distance among 5 populations of Nile tilapia from SSR to AFLP averaged 3.972 02, whereas the ratio of genetic identity averaged 0.937 92. The results about SSR and AFLP could provide reference for other similar studies in this field.
