Livewell oxygen generators are electrical devices using D/C battery power to oxygenate water in livewells and bait tanks and to keep live bait and tournament fish alive in boat livewells. Oxygenators produce oxygen by electrolysis of water. T-H Marine sells Oxygenators™® (electrolysis type). FishO2 ™ oxygen generators filter out, separate oxygen and nitrogen ambient air via pressure swing absorption (PSA); O2 generators dump the nitrogen and deliver oxygen-enriched (80-90% oxygen, 10-20% Nitrogen) when new. Both are battery powered. 

Both are capable of producing oxygen-rich or oxygen-enriched environments (24% oxygen concentrations or greater) inside a boat livewell or bait tank. Oxygen safety (fire safety) rules that are extremely important apply and must be practiced. Oxygen generators are not aerators and not risk free. Oxygen is not air.

Federal, State and private fish hatcheries and professional live fish transporters do not use oxygen generators to insure safe, continuous oxygenation during live haul transport water for many reasons.

Electrolysis type livewell oxygen generators are primarily used by tournament bass fishermen and sold as OEM by many bass boat.
