A shark barrier that comprises an anchoring assembly having a pair of anchors (9) with a flexible connecting element (11) extending between the anchors. The shark barriers also includes multiple spaced apart buoyant resiliently flexible elongate members (15) that are secured at one end along a length of the connecting element of the anchoring assembly to operatively extend generally upwardly from the connecting element. The buoyant members comprise an elongate flexible spine (32) that extends through a series of tubular members (38).

A protective screen against aggressive animals, including a structure formed by frames provided with pointed elements which are installed for the purpose of creating secure zones that are protected against possible attacks from dangerous animals. A series of elemental modules having a square or rectangular tubular frame in polyethylene or hard plastic having four lances directed towards the centre but forming an angle with the plane defined by the frame. Each lance has a shaft of the same material as the frame and a steel metal lance point that is protected against corrosion.

A rod for repelling sharks is disclosed. Magnets are connected to the rod along its length. If necessary, the rod may be extended. Additionally, one or more flotation devices may be connected to the rod to manipulate or adjust the buoyancy of the system, depending on the user's objective(s). The rod is connected to a fishing line once a fish is hooked and is in close proximity to the boat or other structure from which the fisherman is fishing. The weight of the rod and magnets cause the rod to slide down to the end of the fishing line, where the rod will come in contact with the hooked mouth of the fish. As the fish struggles during the fight, the rod creates a protective magnetic field around the fish to deter sharks from engaging the fish.

The invention relates to a system for deterring aquatic animals. The system includes a plurality of deterrent modules which are spaced apart from, and interconnected with, each other, and which are, in use, positioned/located in a body of liquid at spaced apart positions/locations. The deterrent modules are configured to generate an electro-magnetic field(s) between the spaced apart deterrent modules such that, when the deterrent modules are located in the body of liquid, an electro-magnetic field(s) is generated between the deterrent modules within the body of liquid, to thereby form a non-physical barrier between the deterrent modules within the body of liquid. which deters aquatic animals. The system also includes a management module which is configured to monitor the operation or functioning of each deterrent module by receiving data from each deterrent module. The data received from each deterrent module relates to an operation or functioning of the particular deterrent module.

A shark barrier includes a plurality of resiliently flexible, elongate members that extend in a generally upright condition between a sea floor and a sea surface. The elongate members are arranged so as to have the appearance of a thicket, preferably a kelp forest, when viewed from within the water and include magnets to assist in deterring certain shark species. The elongate members may be secured to the sea floor by an anchoring base and are held in the generally upright condition by a buoy or buoyant material held within the elongate members.
