The studbook is an integral tool in the management of species in captivity.
Studbooks maintain the records on an entire captive population of a species.
This data is used by species managers to ensure the best genetic pairings and demographic management of the population in captivity. The studbook keeper is responsible for maintaining a current and historical database on a particular population of animals. They are often called upon for information and advice by other zoos wishing to ensure the best pairings of their animals. The Houston Zoo supports the professional development of its staff through involvement in species management programs, including studbooks. The regional studbook maintains all data within a single geographic region, while the international studbook is global in its perspective, maintaining data on the species throughout the world.
