Distribution, Movement, and Ecology of Etheostoma spilotum (Gilbert), the Kentucky Arrow Darter, in Gilberts Big Creek and Elisha Creek, Red Bird River Basin, Clay and Leslie Counties, Kentucky By: Jonathan Baxter Masters of Science Eastern Kentucky University Richmond, Kentucky 2015 Submitted to the Faculty of the Graduate School of Eastern Kentucky University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE December 2015 Copyright © Jonathan Baxter, 2015 All rights reserved ii Dedication This thesis and love for fish is dedicated to my grandparents Willard (“Granddaddy”) and Sadie Igleheart. Without them and more specifically Granddaddy, I am not sure I would have been introduced to, or developed my passion for, the outdoors. Additionally, I would like to dedicate this thesis to my loving wife, Priscilla, and two beautiful kids, Logan and Isabella, who not only sacrificed their time and patience with this process but also offered endless love and support. iii ACKNOWLEDGMENTS First and foremost, I would like to thank my major professor, Dr. Sherry Harrel, for her expert guidance, friendship, and extreme patience through this process. I would also like to thank my committee members, Dr. Charles Elliott and Dr. Michael Floyd, for their comments and assistance over the span of this project. I would also like to thank everyone that helped me in the field and with logistics; U.S. Fish and Wildlife Service (USFWS) staff (Dr. Michael Floyd, Carrie Allison, Jennifer Garland, Jessica Blackwood- Miller, and Jim Gruhala), U.S. Forest Service (USFS) staff (Sandie Kilkpatrick, Pam Martin, and Kim Tarter), Kentucky State Nature Preserves Commission (KSNPC) staff (Mike Compton and Cory Stringfield), and fellow graduate students, Eric Smith, Colin Arnold, Brajaan Hayes, and Garret Clevenger. In addition, a special thanks goes out to the USFWS and the Kentucky Department of Fish and Wildlife Resources (KDFWR) for funding and financial support. Also, I would like to thank the Red Bird Ranger District of the Daniel Boone National Forest (DBNF) for providing housing and logistical support. Also, special thanks to Eastern Kentucky University for their cooperation and the use of equipment to complete fieldwork and data analyses. iv TABLE OF CONTENTS Chapter Page Introduction ................................................................................................................ 1 Study Area ........................................................................................................................... 6 Study Design ........................................................................................................................ 7 Reach level measurements .................................................................................................. 8 Microhabitat Plots ............................................................................................................... 8 Fish sampling ....................................................................................................................... 8 Microhabitat measurements ................................................................................................ 9 Movement Survey ................................................................................................................ 9 Data analysis ............................................................................................................. 12 Population Estimates ......................................................................................................... 12 Movement Analysis ........................................................................................................... 12 Habitat association ............................................................................................................ 13 Results ...................................................................................................................... 14 Discussion ................................................................................................................. 17 LITERATURE CITED ..................................................................................................... 26 APPENDIX A: .............................................................................................................. 31 Tables ................................................................................................................................ 31 APPENDIX B: .............................................................................................................. 41 Figures ............................................................................................................................... 41 v LIST OF TABLES TABLE PAGE 1.
