Acoustic Tag

Acoustic telemetry for fisheries research employs acoustic tags where are small sound-emitting devices allowing the detection and/or remote tracking of fish in three dimensions. Acoustic telemetry (including acoustic tags) are commonly used to monitor the behavior of fish. Studies can be conducted in lakes, rivers, tributaries, estuaries or at sea. Acoustic tag tracking technology allows researchers to view 3D fish tracks in real-time with sub-meter resolution. Acoustic tags have been employed to help public utility agencies, private firms, and state and federal agencies meet fisheries regulations as defined by the Federal Regulations and Oversight of Energy known as FERC.

Acoustic tags come in an assortment of sizes and weights. To-date, the smallest acoustic tag successfully employed to provide fish behavior data in three dimensions was approximately 0.65 grams (tracking a juvenile salmonid at a length of 125 mm). Tag size increases significantly when tracking larger fish for longer periods of time (i.e. sturgeon).

Famous quotes containing the word tag:

    I believe in the flesh and the appetites,
    Seeing, hearing, feeling, are miracles, and each part and tag of me
    is a miracle.

    Divine am I inside and out, and I make holy whatever I touch or am touch’d from,
    The scent of these arm-pits aroma finer than prayer,
    This head more than churches, bibles, and all the creeds.
    Walt Whitman (1819–1892)
