Transcript of "Livewell oxygen injection"

  1. 1. Livewell Oxygen Injection Texas Parks and Wildlife Department Inland Fisheries Division San Antonio District Office (08/04/11)
  2. 2. <ul><li>Dissolved oxygen is the single-most critical factor for maintaining health of black bass retained in livewells. </li></ul><ul><li>Various oxygen equipment was tested to determine a simple, effective, and safe system for maintaining desirable dissolved oxygen (>7.0 mg/l) in livewells. </li></ul><ul><li>This presentation recommends system components and describes installation, operation, and safety. </li></ul>Complete oxygen injection system
  3. 4. <ul><li>Custom engineered for livewell oxygen injection by Premier Industries. </li></ul><ul><li>Industrial grade and not considered a medical device by FDA or Texas Department </li></ul><ul><li>of State Health Services. </li></ul><ul><li>CGA540 inlet and ¼” barb outlet. </li></ul>Oxygen Regulator <ul><li>Fixed-flow, LPM is factory pre-set to 0.1. </li></ul><ul><li>Dual-stage design which maintains LPM at 0.1 in response to changing PSI. </li></ul><ul><li>High quality PSI gauge which indicates fullness of oxygen bottle. </li></ul>
  4. 5. <ul><li>Use of a CGA540 valve permits use and refill with welding grade oxygen. Use of medical grade oxygen is by prescription only. </li></ul><ul><li>Bottle top will often be painted red by oxygen supplier to indicate its filled with welding grade oxygen. </li></ul>Appropriate size oxygen bottles and associated specificatio ns Size classification Capacity Diameter (inches) Length including valve (inches) Number of 8 hour fishing days for full bottle MD or D 15 ft 3 4.4 20 20 M9 or C 9 ft 3 4.4 14.2 12
  5. 6. <ul><ul><li>Securely mount bottle protecting it and the regulator from impact and excessive vibration. </li></ul></ul><ul><ul><li>Consider different bottles sizes when choosing mounting location. </li></ul></ul><ul><ul><li>Its preferable to route oxygen hose on port side of boat away from wiring and cables located on starboard side. </li></ul></ul><ul><ul><li>Do not locate bottle in boat bilge or in compartments containing oil, gas, or batteries. </li></ul></ul><ul><ul><li>Remove oxygen bottle from boat when not planning to use. </li></ul></ul>9 ft 3 bottle mounted with fire extinguisher bracket in compartment under seat 15 ft 3 bottle mounted with fire extinguisher bracket under console 5 lb. fire extinguisher bracket and large hose clamps 9 ft 3 bottle mounted in wood box in compartment under seat
  6. 7. <ul><li>There are no federal or Texas regulations specific to use and storage of oxygen equipment on recreational fishing boats. </li></ul><ul><ul><li>Aluminum bottles require re-testing every 5 years </li></ul></ul><ul><li>Oxygen by itself is not flammable, however the pure form is a dangerous accelerant and highly reactive to oil-based products. </li></ul><ul><ul><li>Do not smoke around oxygen equipment </li></ul></ul><ul><ul><li>Do not use products containing oil on or around oxygen equipment (e.g. WD-40, silicone, etc) or combustion of these may occur. </li></ul></ul><ul><li>Test all connections with soapy water to ensure there are no oxygen leaks before use. </li></ul><ul><ul><li>Cable/zip ties were inadequate </li></ul></ul><ul><ul><li>Use hose clamps or more secure connectors </li></ul></ul><ul><ul><li>Frequently re-check hoses and connections for leaks and damage </li></ul></ul><ul><li>Do not fill oxygen bottle from another bottle (i.e. transfill). Bottle or valve failure could result. </li></ul>
  7. 8. regulator livewell 1 livewell 2 1/4“ barbed tee <ul><li>Most modern bass boats have two independent livewells. The single </li></ul><ul><li>oxygen line from the regulator is split to form two lines to facilitate oxygen </li></ul><ul><li>injection into both livewells. </li></ul><ul><li>This “T” connection should be made as </li></ul><ul><li>as near as possible to where oxygen </li></ul><ul><li>will be routed thru the rear wall of </li></ul><ul><li>the livewell. </li></ul><ul><li>Durable ¼ “ ID reinforced hose should </li></ul><ul><li>be used between the regulator and </li></ul><ul><li>livewell. </li></ul><ul><li>The hoses running from the tee to the </li></ul><ul><li>livewell wall fittings should be equal </li></ul><ul><li>length. </li></ul>
  8. 9. ¼” barbed tee oxygen diffuser rear wall of livewell <ul><li>Use the soft, flexible hose inside livewells to allow diffusers to remain stable and upright. </li></ul><ul><li>Use equal length hoses inside livewells. </li></ul><ul><li>Use teflon tape on threaded </li></ul><ul><li>livewell wall fittings </li></ul>
  9. 10. <ul><li>Turn the knob counterclockwise on the CGA540 valve to inject oxygen. Turning the valve clockwise will shut-off oxygen flow. </li></ul><ul><li>Diffusers will take 3-4 minutes to pressurize before producing oxygen bubbles. </li></ul><ul><li>Both diffusers have to be submerged in water to work properly. </li></ul><ul><li>Recirculation (air-water mixing) can be used simultaneously with oxygen injection, however oxygen in excess of saturation level with be volatized off. </li></ul><ul><li>Diffusers can be cleaned using fine grit sandpaper. </li></ul>Operation
  10. 11. <ul><li>Safety should be the primary concern if modifying system or </li></ul><ul><li>substituting components. </li></ul><ul><li>Lower quality diffusers are much less efficient and may not achieve desired oxygen level at the recommended oxygen injection rate of 0.1 LPM. </li></ul>
  11. 12. <ul><li>Use oxygen injection together with other proven livewell management and fish care techniques. </li></ul><ul><ul><li>Cooling the water </li></ul></ul><ul><ul><li>Addition of stock salt </li></ul></ul><ul><ul><li>Periodic water exchanges </li></ul></ul><ul><ul><ul><li>http://assets.espn.go.com/winnercomm/outdoors/bassmaster/pdf/b_con_KeepingBassAlive.pdf </li></ul></ul></ul><ul><ul><li>Fizzing </li></ul></ul><ul><ul><ul><li>http://www.tpwd.state.tx.us/newsmedia/releases/?req=20110202d </li></ul></ul></ul>Overall Livewell Management
