Abstract: River dolphins i.e., Amazon river dolphin (Inia geoffrensis); Bolivian river dolphin (Inia boliviensis); Ganges river dolphin (Platanista gangetica); Indus river dolphin (Platanista gangetica minor); La Plata dolphin (Pontoporia blainvillei), are the most endangered species live in geographically isolated rivers and estuaries of South Asia and South America. In addition to these river dolphins, Baiji (Yangtze or Chinese river dolphin; Lipotes vexillifer) was also a freshwater dolphin, recently considered extinct. Habitats of river dolphins, including Indus river dolphins, are experiencing combinations of persistent natural and anthropogenic threats. Habitat destruction and fragmentation, changing climatic conditions, overfishing, bycatch and entanglement in fishing tools, sedimentation of riverbeds, chemical and noise pollution, human interference, and accidental vessel strikes are significant threats to the survival of Indus river dolphins. Conservation efforts like habitat restoration and protection, legislation and fishing regulation, awareness-raising campaigns, dolphin monitoring and research, National and International cooperations, and National Heritage Animal status helped to increase the survival of critically endangered Indus river dolphins.

Keywords: Anthropogenic effects, freshwater ecosystem, habitat restoration, water pollution, species conservation.
