I use a black plastic 55 gallon drum for a live well. I cut a square area out of the top, put a 500 gph thru-hull pump in the bottom of it an made an aerator out of some pvc that sprays the water over the top. It has a wooden latched lid to minimize splashing. I also have fillings that when it is in the boat I can hook it up to a pump to take water in and discharge it back out. It has worked out great for transporting fish, keeping shad alive for striper fishing from one lake to another and used to use it to keep my anchovy's alive when I lived in Sand Diego and went ocean fishing.
