3. Location of Study
Oklahoma
Tournaments
Summer
Spring

4. Major 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 Trials

5. Major 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 out

6. Major 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.

7. Major 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.

Recommendations
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 procedures
