Worldwide, there are twenty seven species of sturgeon that have evolved from an ancient lineage that dates back more the 150 million years. Threats such as the construction of dams, major habitat alterations, and overfishing, however, have resulted in sturgeon having the dubious distinction of being the most endangered group of vertebrates on the planet. The Nechako white sturgeon, with an estimated population of only 600 adults is no exception. Following a series of population studies in the 80’s and 90’s, we embarked on a recovery process in the year 2000 that aims to restore the Nechako population. The establishment of a conservation centre in Vanderhoof in 2014 has further brightened the outlook and has enabled research that is investigating Nechako sturgeon biology including habitat requirement for sturgeon larvae, adult spawning habitat choice and the fluvial geomorphology of critical spawning and incubation areas. I will provide a brief history of the recovery process and review ongoing research projects that our team hopes will bring these fish back from the brink.
