Red Drum and Spotted Seatrout Live‐Release Tournament Mortality and Dispersal
Abstract Although catch‐and‐release fishing tournaments undoubtedly reduce mortality of target species, postrelease mortality and fish stockpiling at release sites remain common concerns related to these tournaments. The impacts of live‐release tournaments on freshwater species have been widely stud...

To concurrently estimate overall post‐weigh‐in mortality and dispersal, we used a Bayesian multistate model. Overall Red Drum post‐weigh‐in mortality (median = 6.12%; posterior credible interval [CrI] = 5.67–9.24%) was lower than overall Spotted Seatrout mortality (median = 30.63%; CrI = 26.74–40.00%).

Within 1 week postrelease, Spotted Seatrout dispersal estimates (median = 87.03%; CrI = 72.96–95.72%) were higher than Red Drum (median = 55.62%; CrI = 42.75–68.10%) or Micropterus spp. in coastal and inland ecosystems. Long‐term stockpiling at the release site was also not present; at the end of our 8‐week observation period, median dispersal estimates were 94.41% (CrI = 87.15–98.19%) and 98.54% (CrI = 93.68–99.82%) for Red Drum and Spotted Seatrout, respectively. Red Drum fisheries may benefit most from live‐release tournaments given that maximum mortality was <10%, but Spotted Seatrout fisheries may also benefit, especially if considerations are made to further reduce tournament mortality.
