Abstract: A method of inducing feeding behavior and accelerating the feeding activity of fish contained within an impoundment of known volume in order to increase the number of fish taken from such an impoundment by baited hook and line within a given period of time. The method includes the introduction of an oxidizing agent to the water of the impoundment so as to achieve an immediate increase in the concentration of oxygen available to the fish for respiration, and the maintenance of the desired oxygen concentration over an extended period of time. In the preferred embodiment of the invention the oxidizing agent employed comprises potassium permanganate.
