The present invention relates to an improved predator deterrent system, particularly for deterring predators of aquatic creatures such as fish in fish farms. In particular the invention provides a predator deterrent system for a submerged fish enclosure comprising: at least one trigger device configured to detect a predator in the vicinity of a fish enclosure; and configured to generate an alarm signal responsive to the detection of the predator; and at least one alarm device responsive to the alarm signal generated by the trigger device, the alarm device comprising at least one electrified enclosure section wherein upon receipt of an alarm signal generated by the trigger device at least one electrified enclosure section is powered. A further predator deterrent system for a submerged first enclosure comprising: a control means for controlling delivery of power to the at least one electrified enclosure section, a method of deterring predators, a method of manufacturing a predator deterrent system and a modular kit for a predator deterrent system are also described. |
