ON-SITE SPERM CRYOPRESERVATION FOR AQUATIC REPOSITORY DEVELOPMENT AND USER GROUP LINKAGE A Thesis Submitted to the Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Master of Science in The School of Renewable Natural Resources by William M. Childress B.S., University of Southern Mississippi, 2011 August 2017 Acknowledgements There are many people that have guided me and provided support along the way during this thesis. I would like to thank my major professor, Dr. Terrence Tiersch, for his guidance, mentorship, and the many opportunities to travel, conduct research, and grow both professionally and personally. I thank Dr. Edward Chesney for serving on my graduate committee and providing me with my foundation in aquaculture and research. I would not be where I am today without his guidance and teaching during my time working for him at Louisiana Universities Marine Consortium. I would also like to thank Dr. Rex Caffey for serving on my graduate committee, teaching me about economics, and strengthening the cost analysis portion of my project. I would like to thank all the members of the Aquatic Germplasm and Genetic Resources Center. I thank Amy Guitreau, Yue Liu, Mike Christensen, Leticia Torres, and Noel Novelo for their support and involvement during this project. I thank all student workers, including Thomas Lee, Austin Daspit, and Megan Chesnut for their hard work. Thanks to Jane Niu for helping to create the GIS map. I would like to thank my entire family for their support and encouragement. Thanks to my mom and dad who instilled my love for the water and shaped me into who I am today. Thanks to my girlfriend, Kandis, for support from my first day of this project to the last and always encouraging me. Lastly, thanks to all my friends and the friends I have made along with way through this journey. ii Table of Contents Acknowledgements ......................................................................................................................... ii List of Tables ...................................................................................................................................v List of Figures ............................................................................................................................... vii Abstract ............................................................................................................................................x Chapter 1.
