LANSING — Biologists and scientists have teamed up to track fish across the Great Lakes using sound—a literal Great Lakes echo. It’s like the world’s biggest game of Marco Polo, but with fish. The Great Lakes Acoustic Telemetry Observation Systems, or GLATOS, is a network of researchers sharing fish-tracking data from across the Great Lakes basin. Acoustic telemetry tracks fish by surgically inserting a tracker into them before releasing them back into the water. As the fish travels, it emits an audible ping that can be picked up by markers placed in bodies of water across the region.
