ABSTRACT:
Underwater acoustical signals or "signatures" produced by various species of fish bait or representing water surface disturbances are recorded by means of underwater recording devices and stored in the form of digital signals in memory devices. A memory device containing data representing the signature of a particular species of fish bait may be installed in a lure or other underwater housing together with an output transducer and the acoustical signal corresponding to the signature of fish bait is broadcast underwater to attract game fish. An integrated circuit chip containing circuitry for reading the memory chip is included in the lure together with a battery which provides power for the integrated circuit chips. The memory and the circuitry which reads the memory and drives the output transducer are provided in separate integrated circuit chips and mounted on one or more printed circuit boards inside the lure or housing. The memory is in the form of a pluggable read-only memory. The lure or housing may be readily opened and the pluggable memory may be readily replaced by another memory containing the prerecorded signature of a different species of bait in order to attract a particular species of game fish. Alternatively, the memory device may be inserted in an on-board computer and interface circuitry connected to the computer drives one or more underwater output transducers broadcasting the signatures.
