Fishing Oxygen Systems

Is this spam? Seems kind of "fishy" to me.

We used them in the mid 90's. Home made of course. We used to tournament fish for crappie. Summer classics was where the fish needed help. We run a standard small welding oxygen tank with acetylene regulator ( turns down further than oxygen reg.) I made a ton of phone calls to fish people. The main piece they said to use was the stone in the tank. Make sure it gives off the smallest bubbles you can find. The smaller the bubbles the more it absorbs in the water.

I use a small aluminum tank that I refill with a whip from my shop bottles. Use a pediatric regulator to get the flow low enough. Works fine.

the stone is the key....

Actually the gas is the key. The dose of oxygen you deliver is the real key and that dose must be controllable... more fish you need to give them more oxygen, less fish, you need to give them less oxygen

Oxygenation of Livewells to Improve Survival of Tournament-Caught Bass by Fishery Biologist Randy Myers and Jason Driscoll TPWP, Inland Fisheries Division, San Antonio, TX Publication 6/2011 Short Reports - Oxygenation of Livewells



— THE SCIENCE — never confuse oxygen with air or nitrogen, these 3 gases are all different

OXYGEN defined by Wikipedia: Oxygen - Wikipedia, the free encyclopedia

AIR defined by Wikipedia: Atmosphere of Earth - Wikipedia, the free encyclopedia

Nitrogen defined by Wikipedia: Nitrogen - Wikipedia, the free encyclopedia

Electrical aerators and water pumps with air entrainment venturi’s and spray bars aerate livewell water air, not oxygen. Aeration is for off-gassing dissolved CO2 and ammonia gas.

Many fishing articles, fishermen and some biologists are often unclear and may be very misleading when it comes to talking and writing about these different gases. How often have you read in fishing magazines or heard fishermen, a biologist, fishing tournament official or salesman tell you that, “more aeration or bigger water pumps will ensure more oxygen and better livewell oxygenation,” or something similar. The glaring fact that will not go away is that pumping more water and more aeration does not and will never ensure minimal safe oxygenation in any livewell or bait tank that is overstocked at any time of the year, especially in the summer.

The reason that fish hatcheries always transport live fish with pure compressed oxygen or liquid oxygen (LOX) is to ensure that their transport water quality will never fall below 100% dissolved oxygen saturation, whether they are transporting one fish (like Texas Parks & Wildlife Department [bass] Lunker Program) or hauling 10,000 fish for a one hour overland trip or a three day trip hauling live fish from Florida to Texas.

It’s easy to confuse air with oxygen and nitrogen because these gases are all colorless, odorless and tasteless and they all make clear bubbles in livewell water.

Science and oxygen gas works better than air, HOPE, water pumps and aerators when it comes to keeping fish alive in summer livewells. The gas you chose to use is the limiting factor, the deliver system must be absolutely dependable else you will tither all day wishing and hoping.

Hay chucktx,

t’s been 3 months now since your announcement last January, the water is warming and the death and dying is coming soon when the water temp hits 75 F (that hot water is predictable every summer, so is the death and dying in livewells).

Pure oxygen gas is the magic that fixes this illusive summer livewell aggravation.

How’s your O2 system coming now? Has TP&WD tested it yet? What are the test results? Is selling it a viable option? Are you selling pediatric medical oxygen regulators with it? You know it’s got to be cheap or no one will buy it, cost no more than a good Rule water pump ($50 or so).

The cost of life in the livewell has limits, > $50 for an oxygen rig is over the limits for most fishermen, even a tournament bass fisherman that touts conservation of resources all the time won’t spring for that much money. After all, most boats come with livewells, bait pumps, pipes, valves, switches, timers, batteries to run this stuff and maybe a battery charger includes ($600).

Shout it out Chuck, cause summer’s coming and low oxygen livewell problems are predictable and always come with summer.

Thanks

I have read this thread but not associated links. There is one piece of the puzzle that I dont see has been accounted for. Temperature. Warm water doesn't hold as much DO and it is much more difficult to dissolve O2 into warm water Vs cold water. If the water is warm which livewells/baitboxes normally are, you can bubble as much O2 as you want to pay for and still not get an appreciative increase in the DO. I would be more tempted to buy from a manufacturer that has documented before and after DO levels at different listed water temps.

I use Mino-Mizers. I believe they work better than oxygenators. In fact I have 4 dozen Crappie minnows in a 5 gallon bucket in the garage right now. Been there since Friday night. I change the water once per day, lost my first minnow today, 3 days later. The minnows are still lively and hard. Some oxygen systems will make the minnows soft and mushy. They don't last long on a hook.

It's summer now, the latter part of June 2015, 6 months down the line chuck and I'm seeing reports on the net about summer tournament fish kills... RE hot summer water, low livewell oxygen and dead tournament fish. Same deal and same dance time as last summer. Do you have your O2 rig yet or has that passed away in the last 6 months since you introduced it here chuck? Fishermen need it now and for the next 3 summer months.
