Meet Our Team
John “Bo” Baxter
-
Bo (he/him) had worked with Conservation Fisheries on and off from 1989 to 1999 and, after a “brief” diversion with the Tennessee Valley Authority, returned for good in 2020.
He started his career in the endangered fish propagation business while working in the back room at Aquatic Specialists, the aquarium store where J.R. and Pat maintained a few tanks of madtoms, which would later become CFI. Bo earned a B.S. in Zoology in 1993 and an M.S. in Zoology in 1996, both from the University of Tennessee in Knoxville while studying under renowned ichthyologist Dr. David Etnier. For his Master’s thesis, he cataloged fish species in the Upper Cumberland River system in Tennessee.
Bo can usually be found coordinating work with our partners, creating plans to improve our efficiency, or discovering systems that allow us to more easily collect and record significant data. Bo has been a catalyst for change in our organization, pushing us to modernize and reach for new heights.

Missy Petty
-
Missy (she/her) began working with CFI as an undergrad from 1998-2001, and as a full-time biologist in 2008.
After being inspired by her work with CFI on imperiled native fishes, she decided to switch her major from Environmental Law to a B.S in Wildlife and Fisheries Science. She graduated Magna Cum Laude from the University of Tennessee in 2001. Missy then went on to Virginia Tech to earn her M.S. in Fisheries and Wildlife Science in 2005 with her thesis work about the life history of the James Spinymussel. She worked for four years as a Research Assistant at the Freshwater Mollusk Conservation Center in Blacksburg, VA prior to rejoining CFI in 2008.
Missy can usually be found expertly managing all of our contracts and grants, as well as communicating with our partners about the ways in which CFI is achieving the goals laid out in our contracts. Her organization skills and love for environmental policy make her the perfect person to keep us connected with those who trust us to perform the hands-on aspects of species recovery and extinction prevention.

Crystal Ruble
-
Crystal (she/her) has been working with CFI since 2004.
She has a diverse interest in all animals and nature, but started culturing her “wet thumb” in high school while owning and working with fish. Crystal earned a B.S. in Ecology and Evolutionary Biology, in addition to a B.S. in Psychology, from the University of Tennessee in 2003, and an M.S. in Wildlife and Fisheries Management from the University of West Virginia in 2013 while still working at CFI. Her graduate work consisted of a comparative study of the early life histories of three darters in the Etheostoma maculatum species complex and a description of the life history of the Diamond Darter.
You can usually find Crystal working around the hatchery and carefully testing new methods for rearing our most difficult larvae. Her long career at CFI makes her extremely knowledgeable about our temperature regimes in the hatchery and the specific spawning periods of many different species.
Rebecca Xiques
-
Rebecca (she/her) has been working with CFI since 2009.
She has unparalleled enthusiasm for learning about southeastern imperiled fishes. Rebecca received her B.S. in Marine Science from Eckerd College in St. Petersburg, FL in 2007. She soon went on to Coastal Carolina University in Conway, SC to receive her M.S. in Coastal Marine and Wetland Biology in 2009 studying nest thermal stratification and survivorship of Leatherback Sea Turtles for her thesis.
Rebecca can usually be found completing various projects around the hatchery. These include everything from constructing our recirculating systems to meticulous care for our larval rearing enclosures. Her can-do attitude makes her a go-to co-worker anytime one may have a question or need a hand around the hatchery.
Derek Wheaton
-
Derek (he/him) has been working with CFI since 2017.
He has been a lover of fish and aquatic animals since he was tall enough to see into the family aquarium, eventually keeping his own aquariums and becoming an active member (and eventual Board Member and Tennessee Regional Representative) in the North American Native Fishes Association. In 2010 Derek received his B.S. in Biology at the University of Mary Washington in Fredericksburg, VA. Prior to joining the team at CFI, he worked for the Virginia Department of Game and Inland Fishes, focusing primarily with rare and non-game species.
Derek can usually be found in the Live Cultures Room, caring for our worms and microorganisms that we feed to fishes throughout the hatchery. His lifelong interest in entomology makes him the perfect fit as our resident culturist, a role he fulfills by constantly experimenting with new food sources and finding ways to fill in potential nutritional gaps to best nourish our species.

Shannon Murphy
-
Shannon (she/her) has been working with CFI since 2020.
She received her B.S. in both Wildlife & Fisheries Sciences and Environmental Biology from Tennessee Technological University. While in college, Shannon served as President and Undergraduate Representative in the Student Fisheries Association (TNAFS sub-unit) and conducted undergraduate research looking at the diel migration of small stream fishes between riffle and pool habitats. During the summer before graduation, she worked as an Aquaculture Assistant at the Tennessee Aquarium Conservation Institute, sparking a passion for reintroduction aquaculture and working with rare and endangered species.
Shannon can usually be found caring for some of CFI’s longest-term resident species and working with our volunteers. Her passion for outreach and science communication make her a great fit for creating and implementing our CFI Volunteer Program.
Curt Brewer
-
Curt (he/him) has been working with Conservation Fisheries since 2022, and was a longtime hatchery volunteer prior.
He received his B.S. in Wildlife and Fisheries Sciences from the University of Tennessee at Knoxville in 2022. While in college he conducted undergraduate research on the passage of small stream fishes across different types of culverts.
Curt can usually be found around the hatchery harvesting live food cultures or feeding our fish. He plans and performs the bulk of our feeding program and has a keen interest in fish nutrition after maintaining his own home aquaria for several years.
Aster Treat
-
Aster (they/them) has been with CFI since 2023.
Their interest in biology and conservation goes back as far as they can remember. From crappie fishing with their grandfather to learning obscure facts about rare crocodilians, understanding under-appreciated critters has always been a driving force. After assisting with several releases, it became clear that they wanted to find their role within this organization.
As CFI has grown and expanded, it’s become apparent that social media marketing and outreach are necessary parts of achieving our mission. Aster is a clear fit to take on this task. In addition to cultivating our online presence, they have taken on the task of using art and data visualization to better communicate the realities of our work, while also planning events to expand and engage our community. By combining their experience running social media accounts for other organizations, working on television productions, and a passion for the natural world, they are helping to shape a new vision of how CFI can speak to partners, the public, and donors.
Andrew Zimmerman
-
Andrew (he/him) has been working for CFI since 2023.
He received his B.S. in Biology with Specialization in Marine and Aquatic Biology from Bowling Green State University in 2012. His focus was initially on marine ecosystems but quickly changed after working on graduate student research projects which focused on freshwater ecosystems where he developed a love for native freshwater fish. After graduating, he worked for EnviroScience, Inc. for 10 years where he specialized in stream assessments, fisheries-based projects, and other assorted environmental surveys.
Andrew is rarely found at CFI’s facility since he is most often leading field efforts to collect broodstock individuals for the hatchery and monitor reintroduction efforts. He spends much of his free time snorkeling as an underwater photographer, capturing stunning imagery of many of the species we’ve worked with.
