SPECIES OVERVIEW
The Indus river dolphin is a rare freshwater cetacean found only in the Indus River system of Pakistan, making it one of the world’s most geographically restricted dolphin species. Once widespread throughout the river basin, the species suffered dramatic population declines in the 19th and early 20th centuries due to direct hunting and human pressure. Legal protection enacted in the 1970s halted deliberate hunting and allowed the population to slowly recover, representing one of the few conservation success stories among river dolphins.
Despite this progress, the Indus river dolphin remains endangered and highly vulnerable. Its survival is threatened by extensive habitat loss caused by large scale water diversion for irrigation, which reduces river flow and degrades critical habitat. A network of gated barrages and dams has fragmented the population into isolated subpopulations, limiting genetic exchange and increasing the risk of local extinctions. Additional threats include accidental entanglement in fishing gear, pollution, and increasing human activity along the river. Continued conservation action, sustainable water management, and community engagement are essential to ensure the long-term survival of this iconic species.
SPECIES RANGE
The Indus river dolphin is endemic to the Indus River system in Pakistan, where it inhabits turbid, slow-moving freshwater channels. The species is most commonly found in deep river bends, confluences, and areas with counter currents, relying on echolocation to navigate and forage in low visibility conditions.
THE THREATS
The Indus river dolphin faces ongoing threats from extensive water diversion for irrigation, which reduces river flow and degrades essential habitat. A network of barrages and gated dams has fragmented the population into isolated subpopulations, limiting movement and genetic exchange. Additional pressures include accidental entanglement in fishing nets, pollution, vessel traffic, and increasing human disturbance along the river.
WHAT WE ARE DOING AND WHY
Operation GRACE is advancing Indus River dolphin conservation through capacity building and veterinary training. In collaboration with WWF Pakistan, Oceanogràfic Valencia, and the University of Las Palmas de Gran Canaria, the team hosted a specialized River Dolphin Veterinary Workshop that delivered both hands-on and virtual instruction tailored to the challenges of rescuing and assessing river dolphin species. The workshop also brought together global experts working to conserve other endangered river dolphins, including the Irrawaddy dolphin in Cambodia and the Amazon River dolphin in Colombia and Brazil.
Building on this foundation, NMMF and its partners are developing a veterinary short course at the University of Veterinary and Animal Sciences (UVAV) in Lahore to expand local expertise. With Operation GRACE support, a UVAV faculty member represented Pakistan at the 4th Annual Asian Marine Mammal Stranding Network Workshop in Okinawa, Japan, gaining practical training in beach rescue and pathology while collaborating with aquatic mammal experts from across the region.
HOW YOU CAN HELP
Your support helps protect the Indus river dolphin and other vulnerable species through Operation GRACE and the National Marine Mammal Foundation’s science-driven research, veterinary expertise, and conservation action. Donations directly support health assessments, rescue and response efforts, and collaborative fieldwork with local experts to better understand threats, improve survivability, and protect the river ecosystems these dolphins depend on.
