Well, if the water looks like a boiling pot of water, probably.
I'm gonna say I think that's your issue. Too much aeration dissolved nitrogen (air) in your livewell water can kill bait and fish.Air is not oxygen, these gasses are very different. Air is a mixture of gasses that contains oxygen (21%), but it primarily contains nitrogen gas (79%). Too much infused nitrogen will kill fish. They need dissolved OXYGEN in a proper percentage to live.

I use the baby bubbles in my 8 quart bucket and in my opinion its not the bubbler unless its so powerful that its making the minnows struggle in turbulent water.its ammonia and skanky water that kills them.and if the bubbler was killing them theres a on/off switch.dont have to blow air up the minnows a$$ all day long.lol
Is there an air stone on the end of that hose of just a hose stuck in the bucket. The pic shows only a few big bubbles and smaller, more numerous bubbles carry more oxygen. Also, oxygen transfer takes place on the surface of the water so if foam accumulates or bubbles are not breaking the surface very little O2 will be in the water.Do be aware of cloudy/stinky water. That means waste products have built up and water needs to be changed. Any store that sells aquarium products will have a decent aerator for 15 -20 bucks. Pick one...
