Pallid sturgeon caught in the Lower Missouri River.

SRX receivers (left) and a ruggedized laptop computer (right) are essential tools for telemetry tracking on the Lower Missouri River.

An ultrasound is used to determine the reproductive condition of female pallid sturgeon.

Alicia Torregrosa download data from a phenocam located in Idaho. The phenocam takes a picture daily and that data is used to help track phenological changes (the timing and vigor of seasonal biological events). The data from the phenocam is used (with other data) to gain a better understanding of vegetation changes over the entire ecoregion.

This Chinook was tagged and then released back into the Klickitat River where we tracked its movements up and down the river.

Mikhail Malin, visiting IBIW scientist, prepares to deploy a high-resolution sidescan sonar towfish below Bagnell Dam on the Osage River.  The CERC and IBIW collaborated with the Missouri Cooperative Fish and Wildlife Research Unit at the University of Missouri to assess the distribution of paddlefish below the dam using telemetry, sidescan sonar, and DIDSON.

Nine-year-old pallid sturgeon wait in holding tanks for their turn to be evaluated by biologists at CERC.  More than 100 pallid sturgeon made the trip from Gavins Point National Fish Hatchery to Columbia on a snowy December day.

Beau Griffith, a biological technician at CERC, stands at the bottom of one of the newly reconstructed ponds designed to conduct long-term studies with sturgeon and other riverine species.  A divider and circulators can be installed in the sandy-bottomed ponds to create the continuous water current that sturgeon prefer.

Here is a study deer after capture and being radio-collared. The tracking information from this collar will enable researchers and managers to track the migrations of mule deer and evaluate their habitat and population performance and will aid in management of mule deer populations in Wyoming.
