In this study, we identified novel family- and genus-specific DNA markers in Mugilidae fish. Genomic DNA was isolated from the blood of fish of 15 families and eighty (80) random primers were used for random amplified polymorphic DNA (RAPD) fingerprinting. When the primer OPAV04 was employed, a novel specific PCR product was observed in the Mugilidae family. In addition, another novel specific PCR product was also observed in the Liza genus while using primer OPAV10. Sequencing analysis revealed that the novel family- and genus-specific DNA fragments were 857 and 419 bp, respectively, and no similar sequences were found in GenBank. Two primers sets were designed based on the family- and genus-specific sequences to confirm the RAPD results and the 571 and 187 bp predicted bands were successfully amplified by PCR. Intriguingly, these two novel specific DNA markers were also effectively used for terrestrial and aquatic animal discrimination. Therefore, the novel family- and genus-specific DNA markers identified in this study can be used as an effective tool for rapid and accurate determination of the Mugilidae family and Liza genus, and even for cross-species identification.
