Book Description
In the Missouri River main stem reservoirs in Montana, North Dakota, and South Dakota, hydrodynamic processes have decreased the lengths of shorelines and changed their configurations during the first 20 to 25 years of impoundment. Physical changes to the shore probably influenced fish abundance and species composition by changing the quality and quantityt of spawning and nursery habitat.

Book Description
This book examines the application of fish community characteristics to evaluate the sustainability and biological integrity of freshwaters. Topics include perspectives on use of fish communities as environmental indicators in program development, collaboration, and partnership forming; influence of specific taxa on assessment of the IBI; regional applications for areas where the IBI had not previously been developed; and specific applications of the IBI developed for coldwater streams, inland lakes, Great Lakes, reservoirs, and tailwaters.

Book Description
North American stocks of Atlantic salmon (Salmo salar) have been declining. One measure being employed to reverse that trend is increased hatchery production. As with husbandry of other animals, intensive rearing is usually associated with higher than normal health risks. Research on diseases of Atlantic salmon can help prevent, reduce, or otherwise control mortality due to problem parasites, infections, and other diseases. For planning of research as well as for diagnostic work, health management, and husbandry, published information on diseases of the Atlantic salmon must be readily available. Inasmuch as the literature is widely scattered, the purpose of this work is to compile a bibliography from international sources on the diseases (detection, diagnosis, identification, and control) of Atlantic salmon. Most of the references are arranged alphabetically by author, either have been annotated by the staff of the Eastern Fish Disease Laboratory, or are abstracts by the author.

Book Description
Toxicity tables for the herbicides acrolein, dalapon, dichlobenil, diquat, and endothal list the test organisms, types of tests, experimental conditions, and test results. Each table is followed by a list of references. The materials provide a useful source of toxicity data on these herbicides to researchers, regulatory agencies, and manufacturers.
