Habitats and movements of shovelnose sturgeons Scaphirhynchus platorynchus in Pool 13 of the Upper Mississippi River were ascertained during April-September 1982 by radiotelemetry, drifted trammel net, and mark-recapture methods. The fish were mostly sedentary, but sometimes they moved up to 11.7 km/d. Most movements occurred in May and July and the fewest in April and June. Long-range movements up to 17 km were noted between activity centers (areas occupied for 3- 93 d). Among 22 radio-tagged shovelnose sturgeons, eight showed homing behavior.
