Abstract

The Ash Meadows Fish Conservation Facility houses the only captive population of the Devils Hole pupfish (Cyprinodon diabolis). Recent population surveys estimate the population at approximately 450 individuals. This captive assurance population was established through the development of novel aquaculture methods and adaptive management of a refugia designed as an ecosystem mimic of the natural habitat. Herein, we summarize 10 years of operations at the Ash Meadows Fish Conservation Facility with emphasis on patterns in egg collections from the wild, egg viability, hatch rates, and survivorship in captivity. This retrospective highlights successes, challenges, and new opportunities that may ensure continued success in the conservation and recovery of the iconic Devils Hole pupfish.
