Increase in number of river dolphins

The last population assessment survey (2008) of the Gangetic river dolphin in the entire Brahmaputra river system has shown a marginal increase in its number. In 2005, the population of the endangered aquatic mammal was estimated at 250, which, according to the latest survey, has increased to 265.

This was disclosed by the members of Aaranyak, a non-government environmental organisation, which has been working in the field of dolphin conservation, among others, for several years.
