Edward F Roseman, PhD
Edward Roseman is a Research Fisheries Biologist based in Ann Arbor, MI.
The emphasis of my research program as Research Fish Biologist centers on aquatic habitat restoration and aquatic science to evaluate and inform management decisions. A substantial portion of my research takes place in Great Lakes Areas of Concern and addresses ecological issues of exceptional interest to the scientific and professional community. I am frequently sought for my expertise in fish early life history (eggs and larvae) sampling and identification and routinely approach my work from an early life history perspective. Results of my research are used to inform management decisions regarding restoration of aquatic habitat and populations that will improve resiliency, ecosystem services, and add value to our natural resources.
Great Lakes aquatic ecosystems are complex, and my research frequently involves development of innovative research tools or unique adaptations of existing methods to accomplish research and management objectives. The scope of my research spans from river and lake-specific research within the Great Lakes basin including connecting waters to global fish population and habitat issues related to restoring Coregonines (e.g., whitefishes and ciscos) in the Baltic Sea and large rivers of the world. The complexity of my research is exacerbated by a multi-jurisdictional international management environment and the frequent need to replace team members lost to attrition. I routinely provide technical assistance related to habitat restoration, serve on Lake Huron and Lake Erie technical committees, supervise the Early Life History and Connecting Waters research laboratory, serve on the Center’s safety and small boats committees, and I supervise several contracted employees.

Data are from biological and physical environmental assessments conducted during 2018 in the lower Rouge River, MI.

This dataset contains data collected on various vessel operations on the Great Lakes and their connecting channels, primarily the St. Clair River, Lake St. Clair, Detroit River, and western Lake Erie, although other locations have been sampled and included in this dataset.

Diet analyses were performed on juvenile lake trout (Salvelinus namaycush) captured by bottom trawl during annual USGS Great Lakes Science Center demersal fish community surveys in mid-October to mid-November 2008?2017 in Lake Huron. This dataset contains lake trout capture information (e.g., location, depth) and diet item data (taxa consumed and their associated lengths).Measured and Modeled Water Velocities in the Detroit River Near Belle Isle from 2014-2017
This data set contains water depths and velocities measured with an acoustic Doppler current profiler (ADCP) used to develop a three-dimensional computational fluid dynamics (CFD) model.

A long-term, multiseason, fish egg sampling program is conducted annually on the Detroit, Saint Clair, and Saint Marys rivers to identify where productive fish spawning habitat currently exists. Egg mats were placed on the river bottom during the spring and fall at historic spawning areas, candidate fish spawning habitat restoration sites, and completed spawning habitat restoration sites throughouHistorical Spawning Sites for Lake Whitefish (Coregonus clupeaformis) and Cisco (Coregonus artedi) in Lake Erie and Connecting Channels, 1850-1960 (ver. 2.0, July 2022)
This data contains coordinate locations for suspected historical spawning locations of lake whitefish (Coregonus clupeaformis) and cisco (Coregonus artedi) across the Lake Erie basin, including the Detroit River, Lake St. Clair, and the St. Clair River.

To investigate the contemporary distribution of lake whitefish spawning and over-winter egg survival within western Lake Erie, potential spawning locations were sampled for eggs from 2016 to 2018.

The St. Clair-Detroit River System is located in the heart of the North American Laurentian Great Lakes, connecting lakes Huron and Erie, contributing over 90% of the inflow to Lake Erie, and providing spawning habitat for many fishes including walleye (Sander vitreus), yellow perch (Perca flavescens), and lake whitefish (Coregonus clupeaformis).

Fischer, Robin DeBruyne, David BennionSpatial extent of contemporary lake whitefish spawning in western Lake Erie
Degradation of lake whitefish (Coregonus clupeaformis) spawning areas in the Detroit River, Maumee Bay, and western Lake Erie reefs and shoals has been identified as a contributing factor to Lake Erie’s population collapse in the 1950s. This decline prompted the United States and Canada to take steps to improve the aquatic ecosystem of Lake Erie.

Research presented in the preceding chapters emphasizes recent advancements in the research, management, and aquaculture of Walleye, Sauger, and Yellow Perch in North America.

RosemanLimited co-existence of native unionids and invasive dreissenid mussels more than 30 Y post dreissenid invasion in a large river system
There are serious concerns for native freshwater mussel survival (Bivalvia: Unionidae) in the Laurentian Great Lakes region after populations were seemingly pushed to the brink of extirpation following the introduction of dreissenid mussels (Dreissena polymorpha and D. rostriformis bugensis) in the mid-1980s.

Walleye (Sander vitreus) is an economically and culturally important species in Lake Erie that has experienced large interannual variability in recruitment. We examined the importance of prey biomass during the larval period to walleye recruitment while also considering the importance of temperature.

MarschallPedigree accumulation analysis: Combining methods from community ecology and population genetics for breeding adult estimation
Estimates of the number of successfully breeding adults (NS) in a population can predict levels of recruitment. However, assessments of NS are often difficult to obtain because encounters with adults are limited due to life-history characteristics, low abundance or other constraints associated with access to critical habitats.

To determine if a survival bottleneck occurs in Lake Erie's lake whitefish (Coregonus clupeaformis) population and explore possible mechanisms responsible, we examined contemporary and historical dynamics of lake whitefish eggs, larvae and juveniles.

Rapids habitats are critical spawning and nursery grounds for multiple Laurentian Great Lakes fishes of ecological importance such as lake sturgeon, walleye, and salmonids. However, river modifications have destroyed important rapids habitat in connecting channels by modifying flow profiles and removing large quantities of cobble and gravel that are preferred spawning substrates of several fish spAuthorsA.

Shallow water riparian zones of large rivers provide important habitat for fishes, but anthropogenic influences have reduced the availability and quality of these habitats.

The St. Clair and Detroit rivers historically supported abundant fish populations. However, like many river systems, these rivers have been greatly altered through the creation of navigation channels and other anthropogenic disturbances, resulting in the loss of fish and wildlife habitat and declines in native fish populations.

Ideally, restoration re‐establishes natural processes in degraded habitats (e.g., flow and sediment regimes).
