"Better Bait Bucket" Polyethylene Bait Tank
Deluxe Round Tanks with Cover
These premium "water in, water out" live bait carriers do an excellent job of holding live bait and will last a lifetime. They're built of durable, white polyethylene in sizes to fit most boats, large and small.
Note that the taller tanks can have the discharge positioned to sometimes run over the gunwale. Consider utilizing two smaller tanks instead of one large one. This allows your use of different size and kinds of bait plus the advantage of having the total tank weight in two separate areas of the boat to help balance the load.
