| Popis: |
DNA evidence is routinely used to identify individual predators responsible for attacks on people and livestock in terrestrial settings. However, the transfer of DNA techniques to aquatic environments for similar purposes is a recent development. To date, DNA barcoding has been used successfully to identify shark species depredating fish catches and biting surfboards and neoprene surfaces. In this study we demonstrate the successful DNA barcoding and fingerprinting of an individual tiger shark from transfer DNA collected directly from the wounds of two shark bite victims within two incidents that occurred 30 days and 85 km apart. This finding supports the existence of problem individuals among large shark species that target humans as potential prey. The successful use of DNA techniques to identify both species and specific individuals responsible for shark bites opens the door to selective removal of these individuals as an innovative shark bite risk management strategy. This selective approach would be a more effective, eco-responsible, cost-effective and ethical solution for vulnerable taxa than ongoing non-selective culling campaigns. |
