Abstract: A bait tank adapted to supply a continuous flow of water through a storage tank having live fish stored therein, said fish being used as fishing bait, wherein the tank is formed having a cylindrical wall defining a storage compartment for unobstructed water circulation therein, an angular channel being vertically formed in the annular wall with inlet openings spaced vertically therein to introduce water in a direction generally parallel to the circular inner side of the tank. Oppositely disposed to the inlet channel is an outlet system including an adjustable gate valve to control the height of the water within the tank, and including a drain gate to allow the tank to be emptied.
