Location: The desert | Once you start recirculating the water it isnt going to take a ton of time to resaturate with oxygen, as long as its moving and mixing with the air it is oxigenating the water. Also, most of the water you are dealing with wont be 100 percent saturated anyways. We worked on a trout stream this summer and I did a bunch of water quality/chemistry tests. Even that trout stream, in areas where the water was moving at about a 1ft/sec rate was only around 85 percent saturated. With keeping suckers in a 50" livewell they can probably use a fair amount of oxygen up. Suckers however are a fairly tolerant species when it comes to Dissolved oxygen, where as trout are very intolerant, especially brookies. Meaning that suckers dont necessarily need high DO contents. A lot depends on temperature as well.
One thing that might be cool to try is to take fresh water up over a thick green weedbed....in these areas it is possible to have DO's above 100 percent because of the respiration from the aquatic plants. See if maybe this helps the suckers liven up a bit if they are looking a little sluggish.
I hope this is semi informative, I'm still "very young" in the waters field, but I am continually gaining a better understanding of how it all works.
