Project Dolphin

• Project Dolphin will be on the lines of Project Tiger, which has helped increase the tiger population.
• The project got in-principle approval in December 2019, at the first meeting of the National Ganga Council (NGC), headed by the Prime Minister.
• It is expected to be implemented by the Ministry of Environment, Forest and Climate Change.
• A Special Conservation program needs to be taken up for Gangetic Dolphin which is a national aquatic animal and also indicator species for the river Ganga spread over several states. As the Gangetic dolphin is at the top of the food chain, protecting the species and its habitat will ensure the conservation of the aquatic lives of the river.
• So far, the National Mission for Clean Ganga (NMCG), which implements the government’s flagship scheme Namami Gange, has been taking some initiatives for saving dolphins.
• Global Experience: The Rhine Action Plan (1987) of the International Commission for the Protection of the Rhine (ICPR) — representing Switzerland, France, Germany, Luxemburg and the Netherlands — helped in the conservation of the salmon fish (also an indicator species).
