The Florida Fish and Wildlife Conservation Commission reports the fish knocked her unconscious and out of the boat on Saturday.
Brianne Megargel and her husband were near Manatee Springs State Park when the fish jumped out of the water and struck her as she sat in the boat.
Witnesses said the impact knocked her out of the vessel.
According to an FWC news release, Megargel's husband pulled her from the water and took her to the park, where a helicopter flew her to Shands at the University of Florida.
The agency said it was the second sturgeon encounter of the year.
