Book Description
Tributaries support diverse spawning habitats for three of the four major sub-stocks of Lake Erie walleye (Sander vitreus). Despite a long history of anthropogenic degradation and the extirpation of other potamodromous species, the Maumee River continues to support one of the largest fish migrations in the Laurentian Great Lakes. To determine if spawning habitat availability and quality could limit production of Maumee River walleye, the longitudinal distribution and relative abundance of walleye eggs deposited in a 34 km stretch of river were assessed. Eggs were collected using a diaphragm pump at ten sites in 2014 and eight sites in 2015 from mid-March to early May. In both years, a sharp decline in mean relative abundances from downstream spawning sites than upstream sites at river kilometer 30 suggest that spawning habitat connectivity in the Maumee River is lower than was previously known, and may be limiting production from the system.

Book Description
Environmental conditions were used to determine relationships with the nearshore fish assemblage of the eastern basin and to model habitat for different life stages of walleye in the eastern Lake Erie basin adjacent to the outflow of the Grand River. Optimal walleye habitat tended to be found along the shoreline of the lake and dependent on the Grand River plume. Generally, there was very little optimal walleye habitat found in the lower reaches of the Grand River. The nearshore fish assemblage tended to be size-structured and related to specific environmental conditions, such as conductivity, temperature, dissolved organic carbon, chloride concentrations, alkalinity, sampling date and abundances of emergent and submergent plants. Improvements in both biotic and abiotic features of habitat in the nearshore and tributaries will enhance the amount of habitat optimal for specific fish species, and thereby the potential abundance of these fish species.

Book Description
Learn about the wonders of Lake Erie and Lake St. Clair in this fascinating and readable book. The most comprehensive reference source available about the lakes, Lake Erie and Lake St. Clair Handbook is an ideal guide for anglers, boaters, swimmers, beach walkers—anyone who uses and enjoys the lakes. The handbook explains, in simple terms, the reasons for the scenic beauty and the natural events that occur in the coastal and offshore waters of Lake Erie and Lake St. Clair, including the St. Clair, Detroit, and Niagara rivers extending from Sarnia, Ontario, to Niagara-on-the-Lake, New York. Individual chapters focus on the land, air, water, and life forms that comprise the natural history and environment of the region—the shoreline topography, wind and weather patterns, water temperature cycles and water level changes, the ecology, and indigenous animal life. Lake Erie and Lake St. Clair Handbook enhances our understanding and appreciation of the lakes and their surroundings by addressing fundamental questions about the Lake Erie region: • how Lake Erie was formed through glacial processes • why daily and seasonal weather patterns occur • causes of the water currents and waves • causes of temperature patterns in the lakes • the location of productive reef features • the species of fish and birds found in the area • the importance of the wetlands • the effect of current and past pollution on the aquatic life in the lakes

Book Description
The darters are a fascinating group of colorful and diminutive freshwater fish whose beauty rivals that of the tropical reef fishes. Native only to North America, the darters occur widely, especially in the United States, but are little known to the general public, largely because of their small size—few exceed six inches and some measure a mere one inch at maturity. This book is the first comprehensive guide to the darters, covering all named and several undescribed forms—140 species in all. Each species account includes a synoptic description to aid in separation of similar species and subspecies, a range map, and discussion of the species' distribution, natural heritage, abundance, and scientific name. An illustrated key and glossary will further assist scientists, students, fishermen, and aquarium specialists in identifying darter species. Central to this volume is the series of 144 handsome color photographs illustrating nearly all known darter species and several subspecies. Most of the specimens shown were caught by the authors at sites throughout the United States, Canada, and Mexico, and photographed by them on site using a recently developed technique that captures the full brilliance of the living fish. Because of their importance as indicators of environmental quality, the darters are receiving increasing attention today from scientists and naturalists. Public interest was focused recently on the plight of the snail darter, but many other darter species are either threatened or endangered, and others face an uncertain future as human activities continue to degrade our waterways. All those with an interest in preserving the natural heritage of our rivers and streams will find this comprehensive guide to the darters an invaluable tool.
