Fish Ladders Designed For Drop Culverts And Central Stoneroller Ecology Across A Latitudinal Gradient, John Arthur Lorenzen

Electronic Theses and Dissertations

Stream connectivity is essential for the persistence of fish populations and maintenance of fish assemblage structure. Stream-road crossings can become barriers resulting in a loss of connectivity. Creating innovative tools for fisheries managers to allow fish passage through barrier stream-road crossings is important worldwide as climate change may force range shifts to stay within thermal requirements. Understanding how populations and metapopulations respond to climate is important as fisheries managers can use this information to make informed management decisions in regards to climate change and possible range shifts. Thus, we developed and tested a fish ladder to retrofit barrier stream-road crossings …
