India Begins Second Dolphin Census
India is counting its dolphins again as part of Project Dolphin.
This is the second time they are doing this.
The first count, which happened between 2021 and 2023, found 6,327 river dolphins.
This time, they are using special tools like hydrophones to listen for dolphin sounds underwater.
They are starting in the Ganga River and will later check other places like the Brahmaputra and Sundarbans.
The goal is to protect these dolphins and their homes by understanding how many there are and what threats they face.
India has started the second census of riverine and estuarine dolphins under Project Dolphin.
The survey began in Bijnor, Uttar Pradesh, and will expand to cover the Ganga, Indus, Brahmaputra, and other regions.
The first census (2021-2023) recorded 6,327 riverine dolphins, with the highest numbers in Uttar Pradesh and Bihar.
The survey uses visual and acoustic methods, including hydrophones, to detect and count dolphins.
The data collected will support conservation planning and policy actions for India's river ecosystems.
