stcroixer, for longer term you need a lot more water per fish. For short term you don’t need that much. I have a 5 gal round beverage cooler that I carry bait in. It has a battery powered bubbler screwed on and that is all you need for an evening trip.
Maybe you guys go through more bait than me, but I can put 20 4-5″ baits in there and fish and they come home with me and then they go into the big tank for long term storage. They won’t live in that small space forever but for a 10-12 hour trip they are fine without a water change. I don’t fill the cooler full of water, either.
Once water hits about 80 it holds a lot less oxygen and I put in a 20oz soda bottle that’s been filled with water & frozen. It lasts a lot longer than ice cubes, they don’t last very long. Ice cubes dump their energy much too quickly and shock your fish and then it starts to warm up.
I got a frabill rotary bubbler last year and it is excellent! I went through a few cheaper ones much too quickly. They were very loud, to the point you wondered if they scared fish away. It was about $30 but still a bargain.
Fyi, aerated and aggitated are one and the same in effect. As long as you have water movement on the surface, O2 is being replenished into the water. If air bubbles do the moving, or a pump does, it doesn’t matter.
When you set up a long term storage tank, you need to cycle it and get the bacteria growing. There aren’t any bacteria you need in a new filter and without them the fish waste will poison fish. So start off with just a few fish like four in a 50 gallon tank for two weeks before adding more. it is tempting to add a truckload of bait when it is easy to catch but if it all dies you just have a mess and it doesn’t help you out. Goldfish are great for cycling tanks.
I am too windy and I know it but it is very frustrating dealing with nasty dead bait when you just want to go fish.
A year or two ago I killed off a coffee can full of suckers/shiners by not cycling the tank first. There was an ugly situation where the circulation pump didn’t have a proper screen and it sucked shiners in and mulched them. it belched out gook and scales and of course in that nasty stew all the fish died again.
