Abstract: A fishing tackle bait keeper for a fishing hook includes an anchor and an extension member. The anchor has a sleeve with first and second ends, and plural ribs coupled to the first end. The ribs project in a diverging arrangement from the first end of the sleeve in a direction opposite of the sleeve first end. The ribs each have a free end. The ribs move from a deployed position to a retracted position, wherein when the ribs are in the retracted position, the ribs are oriented with the sleeve to allow insertion of the bait keeper into a bait, and wherein when the ribs are in the deployed position, the ribs extend out from the sleeve to resist being removed from the bait, the ribs are normally in the deployed position. The extension member is coupled to the sleeve and having an attachment portion for coupling with the hook.

Abstract: A fishing lure has a body with an eye on a rear end portion. A blade is coupled to the eye by way of rings. The blade has two lateral portions, which are non-planar to one another and join together along a ridge. The ring component allows the blade to rotate between limits, with the blade rotating in one direction to a first limit and then rotating in the opposite direction to a second limit. This causes the blade to rotate then stop and then reverse rotation until the next stop. The rotation-stop movement of blade causes the lure to move erratically, mimicking a fish.

Abstract: A fishing lure has a jig, a skirt and a bait. The jig has a jig head, with a hook extending from the jig head. A skirt anchor extends from the jig head toward the point of the hook point along an imaginary line, so as to be offset from the shank of the hook. A skirt is coupled to the skirt anchor. A bait keeper is pivotally coupled to the skirt anchor. The flexible bait is rigged in a weedless configuration, with one end of the bait coupled to the bait keeper and the other end receiving the hook point. The skirt is coupled to the skirt anchor so that the skirt streamers extend adjacent to the bait when the lure is retrieved in water. When a fish bites the lure, the first end portion of the bait body flexes away from the imaginary line for engaging the hook point into the fish to allow the hook to more easily penetrate into the fish.
