Wilde•2003•Fisheries•Presented by: Brian Kiely2Location of Study•Review of previous research•12 studies of dispersal of tournament caught fish–Conducted from 1975-1998–Throughout CONUS3Major Questions•What proportion of fish return to capture sights?•What is the rate and distance dispersed?•Does dispersal differ among LM and SM bass?4Major Questions•Does dispersal differ between lake and river-caught fish?•What proportion of dispersing fish are recaptured?5Major Findings•Black bass rarely return to the site of capture–Possible effects of tournament handling?•Distance dispersed is greater in SM than LM bass6Major Findings•No evidence for different dispersal rates in lakes vs. rivers•Recapture rates were high for both species–No significant interspecies difference7Major Findings•Some individuals feed immediately after release•Anglers often exploit concentrations of tournament caught black bass8Recommendations•A predictive model of the dispersal process is needed•Studies to predict fishery benefits from better holding and handling of tournament caught fish•Studies of dispersal should be on the same scale as those over which fish are dispersed9Recommendations•Studies should population effects of recapture of tournament caught fish•Tournament organizers and participants should heed the recommendations of
