Yellowstone project. Researchers from the U.S. Fish and Wildlife Service - Fish Health Center help Sylvia process her fish

Yellowstone project. Sylvia Murcia is the graduate student working on the Yellowstone project. After the 90 day holding period she removes fish from her tanks.

Fish are euthanized after 10 days exposure in spring creeks and 80 days holding in the lab.

The fish will be held in this holding container for a specified amount time and water quality will be rigorously monitored.

Graduate student Ryen Anderson is currently studying spring creeks to determine if they contribute to whirling disese.

Ryen also studies the worm communities in the spring creeks she is examining.

After the 10 plus 80 days, the fish heads are sent to a lab for whirling disease analysis.

The system is continually monitored to make sure water quality stays within preset parameters. If water quality varies, a pager system is enabled and lab personnel are automatically notified.
