ABSTRACT: Acoustic telemetry is often used to document fish behavior including survival, movement and habitat use. We used information from a combination of a passive acoustic receiver arrays, active tracking, and fisheries assessments to evaluate the potential to reestablish historic Paddlefish (Polyodon spathula) and Shovelnose Sturgeon (Scaphirhynchus platorynchus) fisheries in Lake Sharpe, a Missouri River impoundment in central South Dakota.  In 2015, South Dakota Game, Fish and Parks and U.S. Fish and Wildlife Service began stocking paddlefish into Lake Sharpe to reestablish a sport fishery last open in 1964. We used acoustic telemetry to document movement patterns and habitat use of translocated adult paddlefish (n =40) and determine post-stocking dispersal and survival of age-0 paddlefish (n = 50). We used information from seasonal movement patterns of translocated adult paddlefish to assess the feasibility of creating a shore based recreational fishery.  Post-stocking dispersal rates of age-0 paddlefish was used to prioritize future stocking locations. We also used acoustic telemetry to document movement and population dynamics (recruitment, growth, mortality) of a remnant Shovelnose Sturgeon (n = 50) population in Lake Sharpe. A combination of acoustic telemetry and a mark-recapture study will provide information on basic population demographics of Shovelnose Sturgeon in Lake Sharpe.  We will incorporate Shovelnose Sturgeon population dynamics into modeling software (e.g. FAMS) to set appropriate harvest regulations for Shovelnose Sturgeon.  Here, we provide a case study of using acoustic telemetry paired with traditional fisheries assessment tools as important components of fisheries management decision making in South Dakota.
