E-DNA Confirms Feared-Extinct Sturgeon Alive in Alabama River (4:32)
Partners: University of West Florida, Alabama Division of Wildlife and Freshwater Fisheries


The Alabama sturgeon is critically endangered, so much so that some believed the species had become extinct.

The last documented capture of the freshwater fish was on April 3, 2007, on the Alabama River by biologists with the Alabama Department of Conservation and Natural Resources. An Alabama sturgeon was last spotted near Robert F. Henry Lock and Dam on April 23, 2009, but it was not netted.

However, recent research led by Dr. Alexis Janosik, an assistant professor in the Department of Biology at the University of West Florida, has discovered that though the Alabama sturgeon may have dwindled greatly in numbers, it's not extinct.
