Chinese and Bangladeshi scientists used acoustic tech to detect 146 endangered Ganges dolphins, advancing conservation efforts.
Chinese and Bangladeshi scientists used advanced acoustic technology to detect 146 Ganges River dolphins in the Jamuna River, a breakthrough in conserving the endangered, near-blind species.
The system, developed by China’s Institute of Hydrobiology for the Yangtze finless porpoise, uses real-time audio analysis to identify dolphin echolocation signals amid river noise, overcoming the limitations of visual surveys.
Deployed as part of a China-Bangladesh Belt and Road Initiative project, the technology was fine-tuned on-site, improving detection accuracy and revealing key habitats near sandbars.
Drones provided complementary aerial data.
Researchers highlight the evolutionary similarities between the Ganges dolphin and the extinct Baiji, underscoring the ecological importance of both.
The collaboration marks a shift toward data-driven, cross-border conservation.
