PROJECT DOLPHIN

• Recently, the MInistry of Jal Shakti expressed his displeasure over the slow pace of the approval process for Project Dolphin
• The initiative got in-principle approval in 2019 at the first meeting of the National Ganga Council (NGC), headed by the Prime Minister.
• Project Dolphin is one of the activities planned under Arth Ganga, an ambitious inter-ministerial initiative of the government approved in 2019.
• Project Dolphin will be on the lines of Project Tiger, which has helped increase the tiger population.
• 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.
• Indicator species, organisms—often a microorganism or a plant—that serves as a measure of the environmental conditions that exist in a given locale.
• As the Gangetic dolphin is at the top of the food chain, protecting the species and its habitat will ensure conservation of 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 conservation of the salmon fish (also an indicator species).

Significance:

• It is a reliable indicator of the health of the entire river ecosystem.
• These dolphins and people both favour areas of the river where fish are plentiful and the water current is slower.
• This has led to fewer fish for people and more dolphins dying as a result of accidentally being caught in fishing nets, also known as bycatch.
• Industrial, agricultural, and human pollution is another serious cause of habitat degradation.
• Construction of dams and other irrigation-related projects make them susceptible to inbreeding and more vulnerable to other threats because they cannot move to new areas.
• Dolphins below a dam are threatened by heavy pollution, increased fishing activities and vessel traffic. They also have less food because dams disturb the migration, breeding cycles and habitat of fish and other prey.
