Study Maps Gangetic Dolphin Death Hotspots in Ganga and Hooghly
Scientists studied where Gangetic dolphins are dying in the Ganga river system.
They found many dolphins die from getting caught in fishing nets or hit by boats.
Most deaths happen in the Hooghly River and the Ganga.
The scientists want to create "dolphin ambulances" and fishing rules to help save the dolphins.
They hope to focus on these dangerous areas to protect the dolphins from harm.
This study helps them understand the best places to focus their efforts and resources to keep the dolphins safe.
A new study mapped hotspots of Gangetic dolphin deaths in the Ganga basin.
The Hooghly River accounted for the highest number of deaths.
Accidents, fishing nets, and unknown causes were major factors in dolphin deaths.
The study identified 770km of high-risk river stretches.
Authorities plan targeted interventions, like dolphin ambulances, to aid conservation.
