A garment to repel underwater aquatic creatures. A first component for generating a control signal and a second component for receiving the control signal and transmitting an electromagnetic signal responsive thereto, an electromagnetic field created by the electromagnetic signal radiating from the second component into an aquatic area surrounding the garment. A water sensor disposed on the garment for activating the first and second components to transmit the electromagnet signal when the water sensor senses presence of water.

A wildlife exclusion system for railway tracks is provided which includes an exclusion arrangement positioned to span across the railway tracks at a location along a length of the railway tracks. The exclusion arrangement extends generally perpendicular to the railway tracks and has a series of conductive elements spaced apart from each other to form an exclusion are configured to provide an electric shock to wild animals when particular conductive elements within the exclusion area are bridged thereby. Methods of installing a wildlife exclusion system and methods of discouraging wild animals from traveling along railway tracks are also provided.

An animal deterrent device includes an elongated carrier having an internal cavity. A conductive trace can be coupled to the carrier by a first fastener that extends from the conductive trace to the cavity, which prevents water from contacting the fastener and shorting the conductive trace.

Described is a chondrichthyan repelling system comprising at least one fin comprising at least one electrically conductive electrode for connection to an electrical signal generator. In use, the electrical signal generator generates electrical signals to the at least one electrode to thereby radiate an electrical field which repels chondrichthyans. Also disclosed are various fin designs incorporating one or more electrodes, and a watercraft having one or more fins as described. Various means of connecting the electrodes to the electrical signal generator are also described.
