An expandable fish hook assembly includes a central shaft having one end attached to a fishing line and a plurality of arms or hook members pivotably coupled at or near the other end of the central shaft. The plurality of arms or hooks pivot between a collapsed position, with each arm or hook generally adjacent the central shaft, and a deployed position, with each arm or hook generally angled away from the central shaft. A sliding member engages the central shaft and moves along the central shaft, whereby the sliding member also operatively engages and moves along each of the plurality of arms to support and move the arms between the collapsed and deployed positions.

The movable tail on a fishing lure having a flexible caudal stalk basically comprises a pair of laterally opposing sides, a plurality of fin rays, upper and lower lobes, laterally projecting central drafts and upper and lower lips, and a rear surface. The fin rays extend rearwardly from the caudal stalk on each of the opposing sides of the tail. The upper and lower lobes are disposed rearwardly of the fin rays. The central drafts are disposed rearwardly of the fin rays on the opposing sides of the tail. The upper lips extend between the central draft and the upper lobe on the opposing sides, and the lower lips extend between the central drafts and the lower lobe on the opposing sides. The rear surface extends over an area defined by the upper and lower lobes, the central drafts, and the upper and lower lips.

The various embodiments provide for a fishing lure configured to allow a fisherman to quickly change the body of the fishing lure without having to cut the line. In the various embodiments, the fishing lure may include two sides configured to fit around a center piece tied to a fishing line, whereby a fisherman may quickly changes the sides of the fishing lure by separating the sides from the center piece and assembling two other sides to the center piece. In further embodiments, the center piece may be positioned on the interior of the sides such that a portion of the fishing line is hidden within the fishing lure, thereby improving the fishing lure's presentation by attaching the fishing line to the fishing lure internally instead of to an external protrusion (e.g., a snap swivel) on conventional fishing lures.

A fishing lure including a wire capable of bending and retaining a body at an angle relative to a head. The angle may be between about 0° up to about 90°. The angled head and body causes the head to move back and forth through the water as the lure is being reeled, which in turn causes the body to wag.

A biodegradable hydrogel has been made based on high concentrations of whey protein isolate (WPI). WPI gels of different compositions were fabricated by thermally inducing gelation of high-concentration suspensions of protein, and characterized for compressive strength and modulus, hydration swelling and drying properties, mechanical behavior change due to polysaccharide additives, and intrinsic pore network structure. The gels were shown to be compatible with bone cells and could be used as bone tissue scaffolds. In addition, WPI fibers were produced by electrospinning. Several additives could be incorporated into the WPI gels, including structural additives, growth factors, amino acids, etc. The WPI hydrogels can be made with glycerol to increase flexibility and stability. The hydrogels could be used for tissue regeneration, food protection, controlled-release applications (including drug encapsulation, dietary supplement release, attractant release in lures, nutrient release to plants (fertilizers), column packing for compound separation, and membrane development.

A fishing lure device for use with a fishing line having a blocking portion includes a lure component with an inner passage through which the blocking portion can pass. A lure connector which is connectable to the lure component has a central passage sized for preventing the blocking portion from passing through it. When the connector is connected to the lure component at one end thereof, with a fishing line extending through the passages with the blocking portion being disposed on a part of the fishing line passing out of opposite end of the lure component, the connector is detachable from the lure component and the lure component is removable from the line by passing the blocking portion through the lure component. The invention also extends to a fishing lure assembly, a method of disassembling a fishing lure device from a fishing line, and a fishing lure device kit.

An artificial bait with a split ring has a high tensile strength and an easily detachable hook and prevents the hook from freely rotating in water. In the artificial bait provided with the split ring with the replaceable hook, the split ring is characterized in that at least one end of the wire formed in a ring shape is curved in a direction away from the intermediate portion.
