Inia geoffrensis in Captivity in the United States.

IUCN Species Survival Commission 3: 35–41.


The history of Inia geoffrensls in the United States covers a period of three decades which is characterized by the combined acquisition of as many as 70 animals over the first ten years, an abrupt decline in importation, and a loss of specimens leading to the current captive population of one. Data obtained from several institutions, availablo literature, and the personal files of the senior authors are reviewed. Such factors as the hazards oftransport, longevity, maintenance conditions, necropsy findings, and comparisons between Inia and the more familiar marine species, Tursiops truncatus, are considered. Institutional data are additionally summarized in tabular form. The authors suggest that crowding and/or the overly aggressive behavior of Inia kept in groups contributes to the species'poor longevity record in captivity and that isolated individuals or animals that can be readily separated have a greater chance for survival in a captive environment.
