WALLEYE FISHERY ECOLOGY IN LAKE OAHE OF THE DAKOTAS BY ELI FELTS A dissertation submitted in partial fulfillment of the requirements for the Doctor of Philosophy Major in Wildlife and Fisheries Sciences South Dakota State University 2018 iii ACKNOWLEDGEMENTS This project was funded by the Federal Aid in Sport Fish Restoration Act Study number 1529 administered by South Dakota Department of Game, Fish, and Parks. Additional financial support was provided by the North Dakota Game and Fish Department. Staff of the South Dakota Department of Game, Fish and Parks and North Dakota Game and Fish Department completed the majority of the field work associated with this project. I want to especially thank Paul Bailey, Jason Barstad, Dave Fryda, Mike Greiner, Bob Hanten, Dan Jost, Jason Jungwirth, Russ Kinzer, Hilary Meyer, Kyle Potter, and Mike Smith for their efforts. I also wish to acknowledge the data used in chapters 2 and 5 of this dissertation were collected over a span of greater than 25 years by a small army of South Dakota Department of Game, Fish, and Parks employees. Ryan Johnston, Carlee Fletcher, and Dylan Gravenhof worked as technicians for this project. Many South Dakota State University students contributed to the tagging efforts involved in this study; I want to specifically acknowledge assistance provided by Nick Kludt and Matt Wagner. My dad, Craig Felts, also assisted with tagging efforts during 2014-2016. Literally thousands of anglers voluntarily reported tagged walleyes as part of this study, and I am grateful for their cooperation. Friendly reviews of select chapters in this dissertation were provided by Dan Dembkowski and Josh McCormick and greatly improved the writing and content presented therein. A great deal of support was also provided by staff within the Department of Natural Resource Management at South Dakota State University. Kate Tvedt, Terri Symens, and Dawn Van Ballegooyen provided administrative support and were a joy to iv work with. Many graduate students have passed through SDSU during my time here, and the relationships and conversations with them helped to challenge and shape my thinking about this project and science in general. Jason Breeggemann, Dan Dembkowski, David Deslauriers, Adam Janke, and David Schumann were particularly influential during my time as a doctoral student. One of my dominant feelings as I near the completion of this degree is a profound sense of gratitude to the people who played a significant role in my development without realizing the depth of their impact. While it is impossible to recognize all those folks here, there are a few who I feel compelled to acknowledge. I had two exceptional ecology and evolution professors at the University of Wisconsin-Oshkosh who sparked my interest in population biology: Dr. Gregory Adler and Dr. Bob Stelzer. I didn’t realize it at the time, but I learned everything I needed to know about fisheries biology in Dr. Adler’s Population and Community Ecology class. I’m also happy to report that to this day I instinctively recoil at the use of “data” as a singular noun; data were, are, and shall always be, plural. Dr. Katie Graeb baptized me into academia, taught me how to be a scientist, and has continued to be a valued friend and mentor. Anyone who studies fisheries science at South Dakota State University owes an enormous debt of gratitude to the late Dr. David Willis, and I am personally humbled to be counted as part of the Willis Nation. While writing this dissertation I have often envisioned Dave as the editor, and I hope the content reflects this strategy. I’d like to thank my graduate committee which consisted of Dr. Steve Chipps, and my co-advisors: Dr. Mark Fincel and Dr. Brian Graeb. Steve’s research is everywhere in this dissertation, and so are lessons I learned in his outstanding Aquatic Trophic Ecology v course. Mark has been a great bridge between academia and the state agency environment and is an invaluable resource for all things Missouri River. He’s pretty funny, too. Brian has influenced my development as a fisheries scientist more than any single person. He is a phenomenal teacher and I’m extremely thankful to have spent 8 years learning from him. I thank my family who has supported and believed in me throughout this very long and sometimes frustrating process. My wife, Brandi, has not only supported me, but did so while she herself was a doctoral student. I’m not sure that I could have made it through without her by my side, but I’m forever grateful that I didn’t have to find out. vi CONTENTS ABSTRACT ...................................................................................................................................... viii CHAPTER 1: INTRODUCTION ............................................................................................................ 1 Dissertation Content and Format .............................................................................................. 10 CHAPTER 2: INFLUENCE OF SPATIAL COMPLEXITY AND ENVIRONMENTAL FACTORS ON WALLEYE RECRUITMENT IN A LARGE MISSOURI RIVER RESERVOIR .............................................................. 15 Abstract ...................................................................................................................................... 15 Introduction ............................................................................................................................... 16 Methods ..................................................................................................................................... 18 Results ........................................................................................................................................ 23 Discussion .................................................................................................................................. 25 References ................................................................................................................................. 31 CHAPTER 3: USE OF HIGH-REWARD TAGS AND DOUBLE-TAGGING TO ESTIMATE ANGLER REPORTING AND JAW-TAG LOSS RATE FOR LAKE OAHE WALLEYE ............................................... 45 Abstract ...................................................................................................................................... 45 Introduction ............................................................................................................................... 46 Methods ..................................................................................................................................... 47 Results ........................................................................................................................................ 50 Discussion .................................................................................................................................. 51 References ................................................................................................................................. 55 CHAPTER 4: WALLEYE MOVEMENT PATTERNS INFERRED FROM TAGGING IN LAKE OAHE .......... 64 Abstract ...................................................................................................................................... 64 Introduction ............................................................................................................................... 65 Methods ..................................................................................................................................... 68 Discussion .................................................................................................................................. 78 References ................................................................................................................................. 85 CHAPTER 5: ANGLER RESPONSE TO WALLEYE POPULATION VARIABILITY IN LAKE OAHE, SOUTH DAKOTA ........................................................................................................................................ 103 Abstract .................................................................................................................................... 103 Introduction ............................................................................................................................. 103 Methods ..................................................................................................................................

  • Rainbow Smelt Spawning Monitoring
    PROGRESS REPORT State: NEW HAMPSHIRE Grant: F-61-R-22/F19AF00061 Grant Title: NEW HAMPSHIRE’S MARINE FISHERIES INVESTIGATIONS Project I: DIADROMOUS FISH INVESTIGATIONS Job 2: MONITORING OF RAINBOW SMELT SPAWNING ACTIVITY Objective: To annually monitor the Rainbow Smelt Osmerus mordax resource using fishery independent techniques during their spawning run in the Great Bay Estuary. Period Covered: January 1, 2019 - December 31, 2019 ABSTRACT In 2019, a total of 844 Rainbow Smelt Osmerus mordax (349 in Oyster River, 405 in Winnicut River, and 90 in Squamscott River) were caught in fyke nets. The CPUE in 2019 was highest in the Oyster River with 23.79 smelt per day, whereas the Winnicut River (8.46 smelt per day) and Squamscott River (5.54 smelt per day) were lower. A male-skewed sex ratio was observed at all rivers, a likely result of differences in spawning behavior between sexes. The age distribution of captured Rainbow Smelt, weighted by total catch was highest for age-2 fish, followed by age-1, age-3, and age-4 fish. Most water quality measurements (temperature, dissolved oxygen, specific conductivity, and pH) were within or near acceptable ranges for smelt spawning and egg incubation and development in 2019; however, turbidity was above the threshold in the Oyster River for most days monitored. INTRODUCTION Rainbow Smelt Osmerus mordax are small anadromous fish that live in nearshore coastal waters and spawn in the spring in tidal rivers immediately above the head of tide in freshwater (Kendall 1926; Murawski et al. 1980; Buckley 1989). Anadromous smelt serve as important prey for commercial and recreational culturally valuable species, such as Atlantic Cod Gadus morhua, Atlantic Salmon Salmo salar, and Striped Bass Morone saxatilis (Clayton et al.

  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

  • COSSARO Candidate V, T, E Species Evaluation Form
    Ontario Species at Risk Evaluation Report for Shortnose Cisco (Coregonus reighardi) Committee on the Status of Species at Risk in Ontario (COSSARO) Assessed by COSSARO as Endangered November 2017 Final Cisco à museau court (Coregonus reighardi) Le cisco à museau court (Coregonus reighardi) est un Corégonidé nord-américain, et l’une des 10 espèces de ciscos du Canada. Historiquement, on trouvait cette espèce vivant en eaux profondes (de 22 à 110 mètres; Eshenroder et coll., 2016) dans le lac Huron, le lac Michigan et le lac Ontario. Cependant, on en sait très peu sur son historique et ses besoins en matière d’habitat. On croit que le déclin historique du cisco à museau court est attribuable à la surpêche, ainsi qu’à la compétition et à la prédation d’espèces de poissons non indigènes, qui sont des causes plus récentes (COSEPAC, 2017). La désignation de son statut se complique encore davantage en raison de la possibilité d’hybridation avec différentes espèces de ciscos des Grands Lacs, où certains poissons qui ne peuvent être associés à aucune espèce de ciscos pourraient toujours présenter des traits du cisco à museau court (Eshenroder et coll., 2016). Malgré l’échantillonnage intensif et ciblé, la dernière capture recensée d’un cisco à museau court clairement identifié a eu lieu en 1985 (baie Georgienne, lac Huron; COSEPAC, 2017). L’espèce est probablement disparue, mais comme seulement 32 ans se sont écoulés depuis la dernière capture, elle ne peut être classée dans cette catégorie. Le cisco à museau court est considéré comme étant en voie de disparition en Ontario en raison de sa faible population (< 250 individus).

Under Section 6 of the Flood Control Act of 1944 (Public Law 78-534), the Secretary of the Army is authorized to make agreements with states, municipalities, private concerns, or individuals for surplus water that may be available at any reservoir under the control of the Department. Terms of the agreements are normally for five (5) years, with an option for a five (5) year extension, subject to recalculation of reimbursement after the initial five (5) year period. This proposed action will allow the Omaha District to enter into surplus water agreements with interested water purveyors and to issue easements for up to the total amount of surplus water to meet regional water needs.

    Appendix D Selected Introduced and Native Fish Species of the Missouri River in South Dakota and their Potential as Predators of Pallid Sturgeon Prepared for In Re: Missouri River System Litigation (03-MD- 01555)(and associated litigation) Prepared by Wayne Nelson-Stastny 20641 SD HWY 1806 SDGF&P Missouri River Fisheries Center Fort Pierre, South Dakota March 2004 Introduction This report discusses several native and introduced species to the Missouri River that have increased in abundance or have become important components of the fish community in the mainstem of the Missouri River in South Dakota. Because of the changes in the fish community, whether through increased abundance of a native species or stocking of a nonnative species, concern has been expressed regarding the potential impacts to native species, in particular predation on pallid sturgeon. Therefore, this report examines the reasons behind the changes to the fish community, the changes to the fish community itself, and individual species ecological characteristics. Lastly, the potential for predation of selected species is reviewed. General Change in Missouri River Four mainstem dams, Oahe, Big Bend, Fort Randall and Gavins Point, have dramatically changed the Missouri River that either passes through or borders South Dakota. The Missouri River was often referred to as the “Big Muddy” because of the turbid waters and sediment load. This characteristic was due in part to the two spring floods characteristic of the Missouri River that annually reorganized the river complex of chutes, side channels, back waters and sinuous main channel. A floodplain consisting of highly erodable soils and a relatively low gradient also added to the diversity of habitats and turbidity of the Missouri River (National Research Council 2002).

They are commonly used as bait and have become established in many lakes across the United States following intentional introductions and accidental bait-bucket releases. Once established in a new waterbody, alewives can cause tremendous changes to a lake ecosystem. Alewives first ap- peared in Lake Champlain’s Missisquoi Bay in 2003; they appeared in the Northeast Arm and the Main Lake segments in 2004 and 2005. Alewives are well established in Lake St. Catherine, which drains to Lake Champlain 80+ miles south of the 2004 discovery point. Based on experiences in other states, it is believed that an alewife infestation in Lake Champlain could have substantial eco- nomic and ecological impacts. Because the specific impacts of a widespread alewife infestation on Lake Champlain are uncertain, Lake Champlain Sea Grant and the Lake Champlain Basin Program organized a workshop on February 14, 2006 to learn from resource managers and scientists with experience in the Great Lakes and Finger Lakes of New York.
