Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted.  For more information, please see www.doi.gov/shutdown

Fish Tagging and Tracking

Science Center Objects

USGS Fisheries scientists apply advanced technologies to monitor and assess fish populations and aquatic communities.

Learn more about our research by visiting the web pages below.


GLATOSGreat Lakes Acoustic Telemetry Observation System

GLATOS is a network of researchers who work collaboratively using acoustic telemetry to understand fish behavior in relation to Great Lakes ecology, and provide information useful to fish managers in their decision making.


Migration and Habitat Use of Lake Erie Walleye

Science Center: Great Lakes Science Center

Walleye represent the most important fishery in the Great Lakes in combined terms of harvest and economic value. A cornerstone of management for this fishery is a spatially explicit understanding of movements, habitat use, and habitat availability as these relate to seasonal and age-dependent changes in fishing vulnerability. 


Rock Creek Fish Assessment via Installation of PIT-tag Interrogation Systems

Science Center: Western Fisheries Research Center

Little is known about the life history of steelhead in Rock Creek. The Yakama Nation has asked the USGS to help them deploy Passive Integrated Transponder (PIT) tag technology to elucidate important life history aspects of this fish population.


Snake River Fall Chinook Salmon Life History Investigations

Science Center: Western Fisheries Research Center

The goal of this project is to provide empirical data and analyses on the dam passage timing, travel rate, survival, and life history variation of fall Chinook salmon juveniles passing downstream in the four lower Snake River reservoirs from spring to winter. Serial releases of radio and PIT-tagged fish are being made in the Clearwater River to study changes in migration behavior over time.


Paddlefish Tracking Map - Visualizing U.S. Fish and Wildlife Service Tower and Boat Observational Data

Science Center: Wetland and Aquatic Research Center

Partnering with the Caddo Lake Institute, the USGS WARC Advanced Applications Team developed a web-based mapping application that visualizes the paddlefish tracking observations being collected by FWS.


Yellowstone Lake Acoustic Biotelemetry Project Home Page

Science Center: Northern Rocky Mountain Science Center (NOROCK)

Our collaborative research utilizes acoustic transmitters implanted in adult lake trout to document movement patterns in Yellowstone Lake. This will assist with active netting activity and identification of spawning area that can subsequently be targeted for embryo destruction. These data are critical for expanding management options for suppressive invasive lake trout.
