Abstract: A control device for marine animals comprises an electrical device that applies an electrical voltage directly to a marine animal in order to shock the marine animal, for control thereof. The device preferably comprises a pole or rod having electrical prongs at one end which my be applied to the marine animal, thereby applying and electrical signal having a voltage, amperage and frequency that stuns and/or shocks the animal. The character of the electrical signal is such that the animal is temporarily paralyzed, so that it may be safely handled by humans for bringing it into a watercraft without otherwise damaging the animal.

Abstract: A downrigger apparatus to hold a fishing line at a selected fishing depth in game fish inhabited water, and a sound emitting device attached to the downrigger cable of the downrigger apparatus. The downrigger apparatus includes a reel and a downrigger cable spooled on the reel. The free end of the downrigger cable extends to a depth beyond the selected fishing depth. A downrigger weight is attached at the free end of the cable. A sound emitting device is attached to the downrigger cable and emits sounds attractive to the fish. Sound waves travel through the water a range extending beyond the visual range of the fish. Fish, although out of visual range of the lure, detect the sound and travel toward the source. The fish eventually comes in to visual range of the lure being trolled behind the fishing boat. The fish is attracted to and takes the lure. The sound emitting device can generate intermittent sounds.

Abstract: A voltmeter for measuring atmospheric or other voltages eliminates the dead band without application of high voltages or radioactive isotopes to increase conductivity in the region of the probe. A vacuum tube is operated at substantially reduced conduction in order to achieve high sensitivity and eliminate passive components in the input circuit. A voltage is developed to produce meter indication or control charging or charge-neutralizing circuits. In the preferred embodiment, a meter scale is calibrated to indicate the presence of atmospheric charges of particular interest to anglers. Naturally occurring electrical currents are known to stimulate the feeding of fish.

Abstract: An audio fishing lure system for attracting fish using preselected audio content includes a fishing pole, a fishing line, a lure or hook, an audio source, an aural encoder, and an underwater transducer. Sound reproduced by the audio source, such as a radio, cassette player, or digital playback device, is electrically communicated to the encoder, which correspondingly generates sound waves that modulate the fishing line. The fishing line is optimized to serve as a transmission line. The audio information propagates along the fishing line, into the water, and to the transducer, where the mechanical waves are transformed to sound waves and transmitted into the water, thereby delivering sound to the region about the bait and attracting fish responsive to such content.

Abstract: A fishing lure or decoy is provided, the lure having a casement for receiving an electronic insert. The insert is operated by a microcontroller programmed to implement at least one sequence of operation implemented by at least one of a LED light emitter, a vibration-producing device and an audio transducer. An electrical power supply in the insert provides power to the devices and microcontroller, and a pair of externally exposed contacts switches the microcontroller ON when bridged by water containing electrolytes, as would be found in a fishing area. This also produces an electrical field around the lure, this electrical field also serving to simulate living food creatures to entice fish to bite the lure.

Abstract: Vibrating fishing lures provide water dynamics to attract fish such as by increasing the amount of flashing that occurs and/or by increasing the surface ripple produced by lure vibration. A vibrating fishing lure has an elongate lure body with a cavity that houses an elongate battery and an elongate electric motor. The longitudinal axis of the lure body, battery, and motor are substantially co-linear so that activation of the electric motor causes the lure body to vibrate and to begin rotation about the longitudinal axis of the lure body. A vibrating fishing lure has an eccentrically weighted motor that lies within the surface plane of water that the lure floats upon so that then activation of the motor causes the vibration of the lure body with a maximum amplitude at the surface plane of the water to maximize surface ripple.

Abstract: A vibrating fishing lure provides a circuit board to control application of power from a battery to an electric motor within a cavity of the lure body. The circuit board includes pin receptacles that receive conductor pins of one or more of the various components to allow the components to be plugged in and frictionally fixed to the circuit board to establish electrical connection. Furthermore, the conductor pins frictionally fixed to the circuit board may be non-corrosive so that they may be exposed to the water without corroding.

Abstract: A device is provided for transmitting a sound signal to a fishing lure on a fishing line of a fishing rod. The device includes a vibrating element supported on the fishing rod to transmit vibrations to the fishing rod and means for coupling the vibrating element to a sound signal source to vibrate the vibrating element in response to the sound signal. The vibrating element is movable relative to the fishing rod at a frequency dependent upon a frequency of the sound signal and at an amplitude dependent upon an amplitude of the sound signal. The vibrating element allows sound to be transmitted to a fishing lure without the need of a complex and specially adapted lure. The sound can be transmitted to a conventional fishing lure through the fishing line in the form of vibrations within a range of frequencies audible to the fish. Furthermore, the vibrations can be completely random so as to simulate movements of live bait.

A conventional transmitter and receiver may be used, and the vibration member can be of the type traditionally used in telecommunications paging systems. The lure is adapted to float or the receiver antenna is provided with a bobber or other means to retain a portion of the antenna above the water.

Abstract: The present invention relates to a method and an electronic acoustic fish attractor for attracting fish to a desired location. The method comprises multi-step transmitting of attracting sounds from that location on the outside on various distances into a body of water. There are optimum energy datum points at distances from a source of a sound. SL1<SL2<SL3< . . . <SLn−2<SLn−1<SLn. SL1=I1, where I1 is intensity of a sound source at the first step of transmitting a sound. It includes the maximum excess of a hearing threshold of a fish at which it is not frightened off. I′1 includes the minimum excess of a hearing threshold of fish, which provides an enough active audibility at fish. The natural drop between I1 and I′1 at the first step occurs on very short distance from a source of a sound. At each subsequent step the precisely certain values I1 and I′1 are reached on the greater distances, which can reach several kilometers.

Abstract: A fishing rod comprises a hollow tubular body having first and second open end portions. The fishing rod further comprises a first member provided at the first open end portion of the tubular body and a second member provided at the second open end portion of the tubular body. A rod blank extends through the first member and the tubular body and terminates at a terminal portion which is disposed in the second member.

An air gap is formed around the rod blank in the tubular body so that a vibration is generated on the rod blank by a strike and transmitted along the rod blank to pass through the first member and reach the terminal portion of the rod blank. The vibration is then reflected from the terminal portion of the rod blank and transmitted along the rod blank reversely toward the first member to be amplified by a resonance. The first member receives the vibration amplified by the resonance.
