Can be used for any fish in any season  The Crippled Herring is the most versatile lure you'll ever use. It is natural, both in appearance and in action, and can be used worldwide, everyday of the year, for all game fish, in fresh or saltwater. It is programmed to take advantage of the strong, natural predator instinct common to all game fish. All distressed bait fish actions (stunned, struggling, or dying) have been engineered into this lure.
