ATU Theses and Dissertations 2021 - Present
Decreased habitat connectivity as a result of damming can lead to genetic isolation in fish communities, especially in highly migratory species. Sauger Sander canadensis is a migratory freshwater species native to the Arkansas River. Sauger are highly sought after by anglers during their annual spawning migration in late winter. In order to investigate the impacts Arkansas River dams on Sauger populations, fin clips were collected in the winters of 2019, 2020, and 2021 below eight dams in the McClellan-Kerr Arkansas River Navigational System (MKARNS). Fin clips were also collected from two reservoirs in Kansas to serve as distinct reference populations. …
