Decline in Dolphin Population

Dolphins are animals of aquatic ecosystems. They are found in the sea, brackish water and fresh water. A total of 15 species of marine and harbour dolphins have been reported from Indian waters and coasts.  Besides, the Irrawady Dolphins are found in brackish waters of Odisha. Amongst the fresh water dolphins, the Gangetic Dolphin is found in the Ganges river and its tributaries. Apart from this, Indus River Dolphins have also been reported in Indus River in Punjab.  State/UT-wise population details of dolphins in the country are not collated in the Ministry. However, the latest population assessment of the Gangetic dolphins carried out in Uttar Pradesh, in Ganges and its tributaries during October 2015 indicated around 1263 Dolphins, compared to the earlier estimate of 671 assessed in 2012. Population status of other dolphins is not known.  Diverse pressure on rivers due to human activities, including pollution, is generally considered to impact biodiversity of river ecosystem. Dolphins are part of  river ecosystem also.
