Abstract
Aquatic animal finder apparatus and method include one or more passive transducers for converting sounds, including bio-soundwaves from a living aquatic animal source traveling in a body of water, to electrical signals, the transducer is caused to scan about a selected axis, the electrical signals are filtered to eliminate all man-made signals of a periodic character and pass bio-sound electrical signals. A discriminator is connected to the filter and programmed to pass a predetermined pattern of the bio-soundwave electrical signals constituting a sonic profile, signature or imprint of a selected aquatic animal. The direction of a selected aquatic animal is detected and presented to the user and range, depth and direction of movement of the selected aquatic animal are determined solely from the biosound signals received from the aquatic animal.
