The Amazon river dolphin has historically been kept in dolphinariums. Today, only one exists in captivity, at Zoologico de Quistochoca in Peru. Several hundred were captured between the 1950s and 1970s, and were distributed in dolphinariums throughout the US, Europe, and Japan. Around 100 went to US dolphinariums, and of that, only 20 survived; the last died at the [[Pittsburgh Zoo]] in 2002.<ref name=Cooke>{{cite book|last1=Klinowska|first1=Margaret|last2=Cooke|first2=Justin|year=1991|access-date=20 November 2015|title=Dolphins, Porpoises, and Whales of the World: the IUCN Red Data Book|pages=52–59|isbn=978-2-88032-936-5|url=https://portals.iucn.org/library/sites/library/files/documents/RD-1991-001.pdf}}</ref>
