Using Acoustic Telemetry To Analyze The Impacts Of Common Carp On Wild Rice Restoration, Franklin Zomer Mar 2021

Using Acoustic Telemetry To Analyze The Impacts Of Common Carp On Wild Rice Restoration, Franklin Zomer

All NMU Master's Theses

Wild rice (Zizania palustris) is an important cultural, spiritual, and dietary resource to Lake Superior Ojibwe. Common Carp (Cyprinus carpio) are an introduced species that negatively impact aquatic vegetation through changes in water quality, uprooting of plants, and consumption of seed. Acoustic telemetry was used to document Common Carp movements in Waishkey Bay in the upper St. Marys River, MI where wild rice habitat is present. Exclosures were established to measure the influence of carp presence on wild rice seeding success. Common Carp were observed to spend much of their time in Waishkey Bay but also …


Habitat Heterogeneity Concentrates Predators In The Seascape: Linking Intermediate-Scale Estuarine Habitat To Striped Bass Distribution, Cristina Kennedy Jan 2013

Habitat Heterogeneity Concentrates Predators In The Seascape: Linking Intermediate-Scale Estuarine Habitat To Striped Bass Distribution, Cristina Kennedy

Masters Theses 1911 - February 2014

Predators are key components of aquatic ecosystems and innovative approaches to understanding their spatial distribution are imperative for research, effective management, and conservation. Discontinuities, created by abrupt changes between two unlike entities, are irregularly-distributed, intermediate-scale features that can have a disproportionate effect on organismal distribution within the seascape. Here I use the discontinuity concept to relate the distribution of a predator, striped bass (Morone saxatilis), to physical features within Plum Island Estuary (PIE), MA. I mapped the distribution of 50 acoustically-tagged striped bass during four monthly surveys at 40 sites to evaluate if heterogeneity in physical features concentrated …
