Livewell aerators and bait tank water pumps are always limited by the low oxygen concentration in ambient air (less than 21% oxygen), not by the volume or velocity of air, number and size of air bubbles and total volume of water volume pumped through the well. These mechanical aeration devices pump water/air, not oxygen. Extra unnecessary swimming work increased oxygen demand and oxygen consumption for all bait fish and tournament fish being transported. The amount of oxygen in ambient air and ambient environmental water is always seriously limited to less that 21% oxygen during live transports in livewells and bait tanks.
This serious oxygen limitation combined with minimal overstocking during summer transports is the cause of increased summer livewell mortality and morbidity in livewells and bait tanks. This predictable low oxygen problem in summer livewells and bait tanks is corrected by administering additional supplemental oxygen.
Imagine being injured, acute chest pains, severe physical and emotional stress and scared for your life. EMT’s are transporting you to a hospital that is 8 hours away. You need oxygen, but the EMT transport vehicle has a small electric fan (equivalent to an aerator/bait pump). No oxygen is available for you on this trip. You get to the hospital 8 hours later, you still need oxygen, but the hospital has bigger A/C fans blowing more air on you. No oxygen available for you.
We see this exact scenario happening every summer in livewells transporting live bait fish and tournament bass, crappie and walleye. Air simply does not contain enough oxygen in overcrowded livewells full of live bait and heavy limits of tournament fish. Non-functional aerated summer livewells are often death-wells.
Professional fish transporters bubble compressed welding oxygen in their transport live wells when transporting live fish. Air simply does not contain enough oxygen to meet minimum safe dissolved oxygen water quality standards when bait tanks are overstocked or contain small volumes of water in the summer. As you already know, morbid live bait transporting results are predictable when bait tank pumps and aeration systems fail to deliver enough oxygen.
Anglers using The Oxygen Edge manipulate the dissolved oxygen concentration in bait tank water by simply bubbling 100% oxygen into the water. The result is “supercharging.”
Never entrain pure 100% oxygen into a water pump on the inlet side of the pump via venturi device – FIRE HAZARD even when the water pump is under water inside a livewell. Divers use pure oxygen underwater to cut and melt steel with the torch flame.
