  • Patent number: 5088229
    Abstract: An improved bait tank or bag which can maintain bait over a prolong period by injecting water in a circular motion in the upper portion of the tank and withdrawing it near the bottom. The flow of water in this manner flushes scales, feces and other debris out of the tank or bag. It also eliminates bubbles, which are harmful to bait. The water level in the tank or bag is adjusted by an extension of the outlet pipe which rises to the desired level of the water in the tank or bag. Interior fill pipes are eliminated, leaving an unobstructed smooth surface on the interior of the tank or bag.
