Chambal Palighat River: Why Is There Fall in Dolphins Number

Dolphins are the most amazing marine mammals and are found in every ocean, from the frigid Arctic to tropical seas and even in rivers that flow into the ocean. They have long been popular with people and it is believed that dolphins have been helping humans for thousands of years.

To see these beautiful mammals you should visit Ranthambore National Park. Human activities are one of the most important factors that have resulted in the decrease in dolphin numbers. Overfishing is one activity that has led to the decline in dolphin numbers in the Chambal River. The decrease has also been due to habitat loss, which is caused by damming and sand mining. Pollution from industries such as thermal power plants, aluminum smelters and thermal effluent from paper mills has affected their food supply adversely.

Key Points You Should Know

1. In Chambal, the highest carrying capacity of dolphins is 125.

2. The greatest population number of a biological species that can be sustained in a given environment, given the food, habitat, water, and other resources available, is referred to as the environment’s carrying capacity.

3. The dolphins were first discovered in 1985 at Etowah, Uttar Pradesh, in the Chambal River (a tributary of the Yamuna). More than 110 people were present at the moment.

Major Reasons behind the Decline in Dolphin Number

1. Unfavorable Habitat: Because of fragmented habitats, it is vulnerable to poaching and entanglement in fishing gear.

2. Poaching: Poaching is an issue for both dolphins and gharials because of fragmented habitats.

3.llegal sand mining: Illegal sand mining is rife in MP’s Bhind and Morena, as well as Rajasthan’s Dholpur, endangering the river’s entire ecosystem.

1. Furthermore, the forest team never receives local assistance.
2. To protect the river’s ecology and fauna, the Supreme Court’s Central Empowered Committee (CEC) enforced a mining prohibition in the sanctuary area in 2006.

 4. Water consumption: Chambal is a lifeline for three states: MP, UP, and Rajasthan, and inhabitants withdraw water on a regular basis.

1. It has resulted in a progressive drop in water levels, which must be addressed in order to save the dolphins and gharials.
2. Dolphins are a fragile species with a scarcity of research. Research of their favorable environment and communication system is required.

 The MP Forest Department has cooperated with scientists from the Wildlife Institute of India (WII) to conduct research in Chambal to protect and increase the number of dolphins.
