Abstract: This invention relates to a fishing lure/hook receptacle operable to receive a lure member therein attached to a fishing line or a leader member. The fishing lure/hook receptacle can be directly attached to the fishing line on the end of a fishing rod and reel assembly to provide a compact enclosure to prevent the same from becoming entangled with trees, underbrush, etc. The fishing lure/hook receptacle includes a main receptacle member or tubular shape having a receptacle cover member releasably connected thereto. The receptacle cover member is provided with a conical body member of dome shape having a slot section extended from a central portion down one complete side thereof. The slot section is adapted to receive a fishing line or leader member therewithin and to clamp against the same when in the enclosed sealed condition mounted on the main receptacle member.

Abstract: Magnetism is used to reduce the tendency of a fish hook to snag. A magnet may be attached to a fishing rig, or part of the rig or a hook may be magnetized, so as to attract a movable hook to a relatively shielded position in contact with the rig where the hook is less likely to snag than when it hangs loosely or is free swinging, or magnetism may be used to hold a weed guard in a position where it shields a hook. The strike of a fish can pull the hook free from the magnet or weed guard and enable its point to penetrate the mouth of the fish.

Abstract: A fishing net includes a cord having a multiplicity of strands including an identification strand marked at spaced intervals with sequential numerical codes. The preselected strand is substantially inextricably incorporated in the cord so that the preselected strand extends along the length thereof. The cord is in turn incorporated in the net so that the cord extends substantially from one end of the net to an opposite thereof. The cord has ends located at readily accessible preselected points relative to the net so that a smallest numerical code and a largest numerical code on the cord are easily determinable upon visual inspection of the net.

The device is preferably fabricated from nylon.

Abstract: A lure is provided that allows for a great variety of weights, action and appearance of the lure by interchangeable parts, saving the fisherman time, money, space and weight over buying and carrying a number of separate lure comparable to the permutations available with this lure. The lure has a transparent tube into which different weighted and attractive beads can be inserted after being threaded onto the fishing line. The lure tube has a protruding lip in which there are a number of holes. Threading the fishing line through particular holes governs the kind of action the lure will have when pulled by the line through the water.

Abstract: The invention relates to a lure made in part of resilient flexible material which forms a connection between a front portion which attaches to a fishing line and at least one paddle designed to create a drag against the water in which the lure moves. The resilient, flexible material is of sufficient resiliency or elasticity and thickness so that when the lure is pulled through the water the paddles are deflected back against the pressure of the water and the paddles return to their original shape and position relative to the body when the tension on the line is released. The paddles are sufficiently wide so that when the tension is released, and the paddles return to their resting position, the lure is moved backward by the force of the paddles moving back to the resting position.

Abstract: A hanger is disclosed for use with a fishing line to a lure and provides rigid arms, suspended from a float, through whose distal ends the line is threaded the combination. In this way, movement of one part of the device will serve to effect movement of the other parts of the combination depending on the geometry of the arms.

Abstract: A method is disclosed to provide a substantial reduction of marine corrosion in sea water by micro and macro biofouling. An alternating current is generated of a strength and frequency sufficient to shock marine biofouling organisms and sufficient to upset the normal behavior patterns of the marine biofouling organisms entrained in the sea water passing around or through the structure. A second combination of alternating and direct currents are generated between two strategically located electrodes whereby to release into the water around or within the structure controlled amounts of chlorine ions and copper ions to produce an environment actively hostile to potential marine biofouling organisms. The effect of releasing copper ions and chlorine ions simultaneously is that they co-operate in a synergistic manner that greatly enhances the biocidal effect on marine organisms over and above the effect of the separate use of copper ions and chlorine ions.

Abstract: A rectangular box shaped casting device comprising a bouyant housing containing within a U shaped retaining area in one end of the housing a folded piece of soft absorbent plastic foam material capable of storing a fish attractant scent substance and imparting that scent substance to a lure held captive in the fold of the foam material prior to the release of the lure in flight. The housing is attached to a fishing line with a part of that line embedded within a slit located in the solid end of the housing and the line secured therein by retainer pins inserted in the housing above the embedded line. A predetermined length of line is wound around the housing midway between the ends of the housing. The lure and the predetermined length of line to which the lure is attached are released in flight from the casting device by applying the brake on the spincast reel.
