Ohio DNR Researcher Matt Faust discusses acoustic telemetry on Lake Erie and GLATOS during a recent episode of the AquaKids TV show.

The robofish are coming! A new underwater gliding robot fish with acoustic telemetry receiver completed first round of field tests on in August. Development is a collaboration of MSU (X. Tan, C. Krueger) and USGS (D. Hondorp, C. Holbrook).

Acoustic telemetry is used to evaluate habitat restoration for warmwater and coldwater fish in Toronto Harbor!

Eastern Basin Lake Erie acoustic telemetry work highlighted when researchers Don Einhouse and Jason Robinson were interviewed for the Outdoor Beat TV show! See GLATOS Project ELEWE!

Innovative acoustic telemetry technology is used by scientists to study the behaviors, movements, and interactions of important fish species in the Great Lakes.
