Disclosed is a method for guiding aquatic organisms. The method includes disposing a plurality of electrode units at a distance from one another in water; and applying an electrical pulse to at least one electrode unit of the plurality of electrode units to generate an electric field and/or a magnetic field around the at least one electrode unit to guide the aquatic organisms by stimulating the aquatic organisms with the generated electric and/or magnetic fields.

An organism inducing device, installed on an installation surface, includes a tile-shaped body; a plurality of electrodes provided to a top surface of the body; and a processor configured to separately control power to be supplied to each of the electrodes, using power supplied from a predetermined power source.

A selective access system, and methods of making and using such a system, whereby the selective access system includes a container having an interior space defined by a side wall disposed between opposing top and bottom walls; an opening disposed within the side wall, the opening communicating with the interior space; and a cover slidably engaged with the container, the cover configured to slide upward and downward between a first position and a second position. In the first position, the cover overlays the opening; in the second position, the cover disposes away from at least a portion of the opening to permit access to the interior space. The selective access system can further include an electrical conductor coupled to the container, whereby the electrical conductor can deliver a nonlethal electrical shock to an animal which comes into contact therewith to deter the animal from the selective access system.

Systems and methods for effectively repelling pest animals (e.g., birds), including drones that adopt complex deterrent strategies (e.g., cooperative strategies), establishing a fuzzy boundary for a geofenced area and altering pest deterrent device flight patterns based on the characteristics of the fuzzy boundaries. Deterrence strategies can be selected based on the type of pest animals, and new deterrence strategies can be generated based on outcome feedback from previous strategies (e.g., combining aspects of preexisting deterrence strategies by utilizing an AI system). Drones can be automatically maintained by comparing current drone operational status with a predetermined threshold level. A maintenance robot (e.g., a drone) can autonomously rescues a working robot (e.g., another drone) that is in trouble.

An improved exclusion barrier including a plurality of elongate members extending in a generally upright condition between a sea floor and a sea surface. The elongate members are improved to provide a more uniform surface area for the prevention of sharks passing through upper portions of the barrier and maximizing the exclusion capabilities of the overall barrier network. The elongate members include, in addition to permanent magnets, hydro-electric power generation mechanisms for powering electro-magnets within the elongate members to produce a stronger electro-magnetic deterrent field across the barrier network, and also include telescoping mechanisms to allow for a variance in length of each member in coordination with changing wave and water levels and to provide additional pump action for hydro-electric power generation within each elongate member. The exclusion barrier is also secured to the sea floor by an anchoring base having evenly spaced anchoring locations.

Some embodiments may be of spearfishing apparatus fitted with at least one magnet configured to repel sharks away from the spearfishing apparatus. The spearfishing apparatus may be one or more of: a spearfishing shaft, a spearfishing tip, and/or a spearfishing gun. Such magnets may be electromagnets powered by batteries in some embodiments.
