Pesut Mahakam (Orchaella brevirostris) is an Indonesian freshwater dolphin that can only be found in the Mahakam River Basin in East Kalimantan. The Mahakam River is the main habitat for these animals, distributed from the Mahakam Delta (Samarinda) to West Kutai (Melak), while the lake and swamp are cruises for playing and foraging. The distribution of the Mahakam Pesut (Orchaella brevirostris) in the Mahakam River has always shifted from time to time. The study was conducted in 2017 - 2018 in Samarinda, Kutai Kartanegara and West Kutai, East Kalimantan, with survey methods and direct interviews with fishermen, community members, the Marine and Fisheries Service, and the Natural Resources Conservation Agency (BKSDA) of East Kalimantan Province.
