ABSTRACT:
Signals generated electronically at a variety of frequencies are broadcast under water in the presence of various species of aquatic animals and any reaction of the aquatic animals in response to the broadcast signals is noted. A frequency synthesizer is used with an underwater transducer to generate and broadcast signals at a variety of frequencies and frequency synthesizer control words associated with observed behavior are recorded. Subsequently, the recorded control words are applied to a frequency synthesizer connected to an underwater transducer to influence behavior of identified species of underwater animals in a desired manner. Indices representative of various recorded signals may be embodied in a submersible device, such as a lure or the like, from which a reproduced signal may be broadcast to attract, repel, or otherwise influence the behavior of identified species of aquatic animals.
