The war on sharks has been waged with shock and awe at times. Eric Clua, a professor of marine biology at the École Pratique des Hautes Études in Paris, said the rationale behind shark culls in the past was simple: fewer sharks, fewer attacks. “They are killing sharks that are guilty of nothing,” said Dr. Clua, who studies the ocean predators up close in the South Pacific. Dr. Clua said he has found a way to make precision strikes on sharks that have attacked people through a form of DNA profiling he calls “biteprinting.” He believes it’s usually just solo “problem sharks” that attack humans repeatedly, analogizing them to terrestrial predators that have been documented behaving the same way. Dr. Clua said that problem sharks could be dispatched the same way.
