The frozen water bottles work great along with an aerator while I am fishing. I am trying to find a way to keep them alive so I can buy a bunch of shiners at the beginning of my days off every other week and keep them alive all week, rather than having to run to buy new ones each day.

I love it during the cooler months because I can keep a ton of minnows in buckets for several weeks at a time and only lose a few each week.
