Inserting an Acoustic Telemetry Tag into a Lake Trout, Lake Superior
Detailed Description
Biologist Mike Lowe, USGS, is surgically inserting an acoustic telemetry tag into a lake trout in Lake Superior. These tags emit a 'ping' which can be heard with a sensistive hydrophone that tells the scientist the location of the fish so their movements can be tracked, in this case, to help us understand spawning behavior.
