Gilliland2002American Fisheries Society SymposiumRachel McNinch3Location of Study•Oklahoma–Tournaments–Summer–Spring4Major Questions•What is the mortality rate of tournament fish vs. control fish?–1995 Spring and Summer Mortality Study•What livewell treatment results in the lowest mortality?–1996 Summer Livewell Treatment Comparisons•Does adding pure oxygen to livewell water reduce mortality?–1998 Livewell Oxygenation Trials5Major Findings•1995 Study–Total Summer mortality > Total Spring mortality–Control fish had high delayed mortality–25% boats not using recirculation systems to aerate livewells–DO in livewells with recirculation systems > livewells with out6Major Findings•1996 Study–Teams with no fish care instructions •Worst livewell environments•28.8 degrees C, 4.7 DO, 32.3% Total Mort.–Teams with flow through aeration•27.4 degrees C, 6.1 DO, 24.7 % Total Mort.–Teams with ice, salt, and recirculation•Lowest Total Mortality•25.7 degrees C, 5.9 DO, 17.2% Total Mort.7Major Findings•1998 Study–Continuous freshwater flow-through and recirculation/ aeration•32 degrees C, 5.4 DO, 14.9% Total Mort.–Oxygenation•30.3 degrees C, 17.9 DO, 6.7% Total Mort.8Recommendations•Education of anglers –Fishing publications, news releases, internet websites, TV fishing programs•At minimum run freshwater flow-through aerator pumps•Spring vs. Summer•Follow WIK program weigh-in
