Fish Telemetry

Active

By Central Midwest Water Science Center August 27, 2018

To monitor fish movement in selected rivers, the USGS has installed near real-time receivers for fish tags. These receivers detect the presence of acoustic tags that have been surgically implanted into a variety of fish species. The tag detection data can provide information about how far fish are moving in a river system, changes in fish population distribution, and, when viewed with flow and water temperature data, how river conditions influence fish movement.
