Explanation:

The census of one of the world’s most threatened cetaceans, the Indus river dolphin (Platanista gangetica minor) — a freshwater dolphin that is found in river Beas, is all set to commence in the winter as part of a project by the Centre.

• However, Punjab’s wildlife preservation wing has gone a step ahead to not only protect the dolphins but also their natural habitat.
• The Indus river dolphin is classified as endangered by the International Union for the Conservation of Nature (IUCN) and, until recently, it was believed that these dolphins were endemic to Pakistan.
• But in 2007, a remnant but viable population of Indus dolphins was discovered in Punjab’s Harike wildlife sanctuary and in the lower Beas river.
• Since its discovery, research is being done by Punjab’s Department of Forests and Wildlife Preservation in partnership with WWF-India on the current distribution, habitat use and population abundance of the mammal.
• The Indus river dolphin was declared the State aquatic animal of Punjab in 2019.
• Extension programmes will be held in Punjab to develop a group of dedicated individuals, called ‘Beas-Dolphin Mitras’ [friends and protectors] of the river Beas.

Hence only statement 2nd is correct.
