- Abstract
Freshwater fish populations are facing numerous threats including habitat loss and degradation. As such, much effort is devoted to restoring degraded habitats and restoring access to spawning habitats. In this thesis, I conducted a narrative review on sturgeon spawning habitat characteristics and biological productivity outcomes in support of functional monitoring for mandated offsetting measures. While sturgeon life history characteristics limit the feasibility of functional monitoring, this approach can be applied to other fishes. Biotelemetry was used to guide efforts for restoration of fish populations in a river system fragmented by a dam. The dam was a barrier to migration for Lake Sturgeon (Acipenser fulvescens), but Walleye (Sander vitreus) did not fully migrate to the dam during the spawning season. These findings provide evidence for benefits of restoring river connectivity by removal of the dam but also consider impacts that dam removal would have with further invasion of non-native species.
