A simple and rapid method was developed to identify the source species of pufferfish products. Randomly amplified polymorphic DNA (RAPD) analysis was applied to identify 8 species of pufferfish. Commercial kits were used for DNA extraction and amplification. Simultaneous identification was possible by polyacrylamide gel electrophoresis of PCR products. Two primers were chosen based on the result of pre-examination with 40 primers, and the PCR conditions were optimized. Characteristic RAPD patterns were obtained for each pufferfish species. The developed method was applied to identify the source species of 26 pufferfish products. The results suggest that the developed method would be useful for verification of the labeled species of pufferfish products.
