For the critically endangered Irrawaddy dolphin, fishing gear is a deadly threat. In Indonesia’s Mahakam River, two-thirds of dolphin deaths in the past 25 years were drownings caused by entanglement in fishing nets. Now a relatively inexpensive electronic device known as a “pinger” shows promise for preventing dolphins from becoming entrapped. These underwater noisemakers have been used to protect various marine life, but this is the first time they’ve been proven effective at safeguarding freshwater dolphins.
