Acoustic Telemetry Provides In-Depth Look into Fish Behavior - Video
"Watch the video for a look into acoustic telemetry research and the GLATOS
network, one of the most innovative elements of the Commission's research program."
With six quadrillion gallons of freshwater in the Great Lakes, it's nearly impossible
to keep track of the innumerable fish that call the lakes their home. Yet, understanding
fish behaviors is critical to improving how their populations are managed in an
ever-changing system. Scientists have been left to hypothesize the answers to endless
questions, including: Where do fish spend their lives? What migration patterns do
fish follow each season? Where does fish spawning occur?
Thanks to the Great Lakes Acoustic Telemetry Observing System (GLATOS), researchers
and the public can find out the answers to these questions and more. With support
from the Great Lakes Restoration Initiative and the Great Lakes Observing System,
GLATOS was created by the Great Lakes Fishery Commission to study the behaviors,
movements, and interactions of important fish species in the Great Lakes using innovative
acoustic telemetry technology. With the detailed information provided through GLATOS,
scientists are able to track fish movements with remarkable precision and uncover
the previously unknown lives of Great Lakes fish species. Watch the video below
for a look into acoustic telemetry research and the GLATOS network, one of the most
innovative elements of the Commission’s research program.
Acoustic telemetry tracks the movement of internally-tagged fish using a network
of underwater receivers located strategically along fish migration routes, spawning
areas, and other places of scientific interest. As a fish swims near a receiver,
the internal tag transmits, or “pings,” a unique ID number, which is logged by the
receiver. The receivers – small data-logging computers also called hydrophones –
listen for pings and record the date, time, and ID number for each tagged fish that
swims by. The vast GLATOS network consists of more than 500 receivers and more than
5,400 tagged fish of 33 different fish species. To date, more than 168 million pings
have been recorded. These records supply researchers with valuable information to
improve monitoring, control, restoration, and management efforts in the Great Lakes.
