Paperback. Condizione: New. Print on Demand. This book examines the relationship between the composition of the riverbed gravels in salmon spawning grounds and the successful hatching of salmon eggs and development of salmon larvae. The author describes methods for measuring the gravel composition, and presents a relationship be…tween the volume of solids less than a certain minimum dimension and the permeability coefficient of stream bottom materials. This permeability is critical to the survival of eggs and larvae. The author compares gravel composition and permeability of spawning grounds that support varying densities of spawning salmon, demonstrating differences between productive and less productive spawning grounds. The author also discusses temporal changes in gravel composition associated with spawning, logging, and flooding. The findings have significant implications for understanding the factors that affect salmon populations and for managing salmon habitats. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.
