Transcript

  • 1. The Oxygenator How well does it work?
  • 2.
    • The Oxygenator is battery-powered device purported to increase oxygen in livewells.
    • According to the manufacturer, it splits water (H 2 0) into its two basic elements,
    • hydrogen (H) and oxygen (O), resulting in formation of dissolved oxygen.
    • More information about the device can be found at the manufacturer’s website: www.keepfishalive.com
  • 3.
    • Both the Portable and the Pro Livewell Flush Mount models of the Oxygenator were evaluated.
    • The Portable model was used in a 2006 Skeeter and the Pro Livewell Flush Mount was installed into a 2008 Skeeter. Both boats had two independent 15- gallon capacity livewells.
    • For each boat and Oxygenator combination, six one-hour trials were conducted with oxygen level measured every 10 minutes.
    • Two trials were conducted for each of the following:
      • Recirculation system only
      • Oxygenator only
      • Oxygenator and recirculation together.
    • Livewells did not contain fish.
  • 4.
    • Portable Oxygenator Test Results
    • Recirculation produced substantially more oxygen than the oxygenator and raised oxygen level to near saturation in 10 minutes.
    • Using the Oxygenator together with recirculation increased oxygen by only 3.8% over recirculation only.
    Water temperature = 75 F Oxygen saturation = 8.4 PPM
  • 5.
    • Pro Livewell Flush Mount Oxygenator Test Results
    • Oxygen increased minimally using recirculation and recirculation together with the Oxygenator. Oxygen did not increase when using the Oxygenator only.
    • Using the Oxygenator together with recirculation increased oxygen by only 3.8% over recirculation only.
    Water temperature = 68 F Oxygen saturation = 9.1 PPM
  • 6. Conclusions and Recommendations
    • The Oxygenator produced less oxygen than standard recirculation on two Skeeter Boats.
    • The Oxygenator increased oxygen by only 3.8% when used together with recirculation.
    • If using the Oxygenator, run recirculation system continuously to maintain sufficient oxygen in livewells.
