| Description | Several shallow water studies of fish behavior have used a methodology called the tracking transducer. The principle of tracking radar, aligning the antenna beam with a target, was applied with an acoustic split-beam transducer and dual-axis rotators for tracking individual fish over long periods of time. Initial studies with active acoustics have evolved an acoustic tag tracking method that is proposed for tracking both juvenile salmon and pelagic sharks. This paper documents the present state of the tracking methodology and proposes methods to track salmon, sharks or other species both with echoes and by using acoustic tags that will allow behavior, abundance and associated pelagic assemblages to be determined. |
