    An Evaluation of Louvers and Bypass Facilities for Guiding Seaward Migrant Salmonids Past Mayfield Dam in Western Washington
    (The Division, 1967) Thompson, J S; Paulik, G J
    The Mayfield Dam downstream migrant fish facilities consisting of louvers and a bypass did not adequately guide juvenile migrant salmonids from water leading to the turbines. Attempts were made to improve the guiding efficiencies that included increasing the water velocities entering the bypass, simulating a wider bypass, screening part of the louvers near the bypass, and totally screening the louvers. Desirable results were achieved with total screening. Some of the interrelated factors influencing the guiding efficiencies of the downstream facilities were the reluctance of fish to readily enter the bypass, time of day, numbers of fish, size, and visibility. The variable factors affected all species in a similar manner.

    An Annotated Bibliography of Fishways: Covering also Related Aspects of Fish Migration, Fish Protection, and Water Utilization
    (The State University of Iowa, 1941) Nemenyi, P
    The literature of the fields indicated in the title is found in so many different periodicals and access to some of them is so difficult that an attempt towards completeness, particularly under war conditions, would be futile. However, an effort has been made to give to this bibliography a fairly comprehensive scope in the sense that it includes abstracts and titles of papers covering an entire group of interrelated subjects; and to make it as far as possible representative of all significant trends of recent progress in these fields attained mainly in western and northwestern Europe, as well as in this country. Accordingly, some older literature has been included, but that describing recent development has been emphasized.

    Fish Biomechanics
    (Elsevier, Inc., 2006-01-01) Shadwick, R E; Lauder, G V
    Biomechanics has emerged in the past twenty years as a burgeoning enterprise that integrates approaches from engineering with studies of animal function. With over 35,000 species, fishes are the largest clade of vertebrates and demonstrate remarkable diversity in body form, ecology, behavior, and physiology. Fishes are critical components of the earth's environment and understanding how fishes function is essential for future advances in conservation and fisheries biology, understanding major patterns in the evolution of fishes, and in the construction of new underwater robots based on the principles of fish functional design. In Fish Biomechanics, leading workers in the area of biomechanics review major functional systems in fishes, and provide an overview of new approaches and techniques that are allowing long-standing questions about fish functional design to be addressed. Chapters are written to allow the non-specialist in biomechanics to understand the approaches and concepts that underlie the remarkable recent advances in our understanding of fish respiration, locomotion, prey capture, physiology, and sensing of the environment.
