This disclosure provides a method of detecting and deterring a target animal from a target area. A target area is positioned within the field of vision of a video camera connected to a computer processing system. An animal identification computer program using convolution neural networks and deep learning computer programs and camera images rapidly detects a target animal. The animal identification computer program is trained to identify target animals accurately using a learning algorithm and related machine learning technology. The time to deploy a deterrent against a target animal from the instant of detection is 2 seconds or less so that little or no time is available to the target animal to damage the target area.

A method of controlling an anti-fouling system, the method comprising: activating at least one transducer and at least one sensor; analyzing the at least one transducer and the at least one sensor to determine a set of features of the at least one transducer and the at least one sensor which are controllable; generating a user interface, wherein the user interface is based on the set of features of the at least one transducer and the at least one sensor; generating a sound wave from the at least one transducer based on input data; monitoring the performance of the transducer by collecting data from the at least one sensor; and providing the collected data through the user interface, wherein values outside of a predetermined range, further comprise, transmitting an indicator of the values.

Certain types of fish respond differently to certain stimuli than other types of fish. Particularly, predetermined sound or vibration can cause certain types of fish to move away or jump. These reactions by particular types of fish can be used to capture the fish or prevent then from accessing parts of water systems. An exemplary capture mechanism employs multiple receptacles adapted to catch jumping fish from the air. An exemplary barrier of directed sound can prevent fish migration.
