Buy small coolers for small bait:

or a more expensive wheeled cooler for bigger bait.

If on a budget, you can find used coolers for little or cheap $$ all the time at garage sales. Remember that if putting herring or bunker into a cooler you need lots of water for each one, or they'll die quickly.
You can only put herring into a round cooler or they will crash into the corners and damage themselves.




Buy this aerator or one like it, Wally World has them a little cheaper:

Now drill a hole towards the top of the cooler and run the wires through for the bubble maker. I installed a cigarette light plug to the wires to plug into my three way plug for easy in and out of the boat. I also plugged the drain hole so there are no accidents and dead shiners. Mount the bubble maker in the bottom and viola you have a bait tank for well under a $100.00.
