UNIVERSITY OF OKLAHOMA GRADUATE COLLEGE A REVIEW OF THE APPLICATION OF DATABASES IN FRESHWATER FISHERIES MANAGEMENT AND THE EFFECT OF WATER QUALITY ON THE MEAN RELATIVE WEIGHT OF LARGEMOUTH BASS, CRAPPIE, AND CHANNEL CATFISH IN OKLAHOMA LAKES A THESIS SUBMITTED TO THE GRADUATE FACULTY in partial fulfillment of the requirements for the Degree of MASTER OF SCIENCE IN GEOGRAPHY By AUSTIN GRIFFIN Norman, Oklahoma 2018 A REVIEW OF THE APPLICATION OF DATABASES IN FRESHWATER FISHERIES MANAGEMENT AND THE EFFECT OF WATER QUALITY ON THE MEAN RELATIVE WEIGHT OF LARGEMOUTH BASS, CRAPPIE, AND CHANNEL CATFISH IN OKLAHOMA LAKES A THESIS APPROVED FOR THE DEPARTMENT OF GEOGRAPHY AND ENVIRONMENTAL SUSTAINABILITY BY ______________________________ Dr. Bruce Hoagland, Chair ______________________________ Dr. Rebecca Loraamm ______________________________ Dr. Thomas Neeson © Copyright by AUSTIN GRIFFIN 2018 All Rights Reserved. Acknowledgements I would like to thank my advisor Dr. Bruce Hoagland for his advice and guidance throughout my time at OU. His willingness to educate and work with someone who had little to no experience in database development is much appreciated. I would also like to thank Kurt Kuklinski of the Oklahoma Department of Wildlife Conservation (ODWC) as well as everyone else who works at the Oklahoma Fisheries Research Lab. Not only for their help and guidance in the development of this project, but also for their willingness to get me out in the field. I would also like to say thank you to everyone at the Oklahoma Biological Survey as well as my other committee members, Dr. Rebecca Loraamm and Dr. Thomas Neeson, for their advice and input in the development of this project. I would like to let my wife Courtney know how much her patience and support has been appreciated throughout this entire process, as well as for giving me a wonderful baby girl right in the middle of it! Lastly, I’d like to thank my parents for their unfailing love and support, and my father in particular for exposing me to the outdoors and putting me on the career path that I have chosen. iv Table of Contents Acknowledgements ......................................................................................................... iv List of Tables .................................................................................................................. vii List of Figures ................................................................................................................ viii Abstract ............................................................................................................................ ix Chapter 1: Introduction ..................................................................................................... 1 Legacy Data Sources .................................................................................................. 2 The Value of Databases in Fisheries .......................................................................... 3 International Databases ........................................................................................ 3 National and Interstate Databases ........................................................................ 5 State Databases ..................................................................................................... 7 Local Knowledge .................................................................................................. 8 Database Creation, Manipulation, and Maintenance .................................................. 9 Geospatial Databases ............................................................................................ 9 Issues to Address ................................................................................................ 11 Quality Assurance and Quality Control ............................................................. 12 SSP Database Creation ....................................................................................... 14 Conclusion ................................................................................................................ 17 References ................................................................................................................ 19 Chapter 2: Introduction .................................................................................................. 33 Methods .................................................................................................................... 37 Study Area .......................................................................................................... 37 Data Sources and Analysis ................................................................................. 38 v Results and Discussion ............................................................................................. 42 Conclusion ................................................................................................................ 46 References ................................................................................................................ 48 Appendices .................................................................................................................... 69 Appendix A .............................................................................................................. 69 Appendix B ............................................................................................................... 72 vi List of Tables Chapter 1 Table 1.

The thesis consists of two chapters. The first is a literature review of fisheries databases and an overview of my work as a graduate research assistant with the Oklahoma Biological Survey and Oklahoma Fisheries Research Laboratory (OFRL) of the Oklahoma Department of Wildlife Conservation. The Standard Sampling Protocol (SSP) is at the core of both chapters. In chapter 1, I reviewed the fisheries database literature to aid in the development of the SSP Database and emphasize some of the issues that commonly occur with database development and application. This information guided me in the development of a relational database for the SSP data. The resulting database includes approximately 1.6 million records for 150 fish species in Oklahoma. The database schema consists of five tables: Abiotic, Biotic, SSP Species List, OBIS Taxonomy, and OWRB Lake Data. Chapter 2 employed the SSP database to determine
