A study of sturgeon in Hells Canyon determined a significant portion of the long-lived fish have hooks and other fishing tackle in their digestive tracts, but they seem to process and pass the metal without harm. Fisheries biologists with the Idaho Department of Fish and Game and the Idaho Power Company scanned more than 2,000 sturgeon with metal detectors and used a portable X-ray machine on about 450 to document the prevalence of fishing tackle in the bellies of the fish.
