This direct conservation role contemplates the possibility to maintain long-term ex situ populations to preserve options for the future. The ex situ populations are a potential future source to build up (long-term) populations for reintroductions. This role would be more an Ark role to those species within this family that are already facing extinction. After reintroduction of those populations have taken place, they will still be needed as insurance population to evaluate whether reintroduction has been successful.
This role would focus on different types of research such as disease management, population management, reproductive biology.
In January 2024, the Poeciliids EEP manages seven species:
