About this Item

Print on Demand. This book examines the horizontal and vertical distribution of juvenile salmonids in the upper section of Mayfield Reservoir, a man-made body of water in Washington state. The author's detailed study was conducted from April 1964 to June 1965, using gill nets and trawls to collect data on the distribution of juvenile coho salmon, chinook salmon, and rainbow trout. The findings suggest that most juvenile salmonids are found in the upper 10 meters of the reservoir, with their distribution influenced by physical factors such as water temperature, flow, and turbidity. The author discusses the implications of these findings for the design and placement of fish collection devices in reservoirs, and provides valuable insights into the behavior and ecology of juvenile salmonids in this type of environment. The book is well-written and accessible to a general audience, making it a valuable resource for fisheries biologists, ecologists, and anyone interested in the conservation and management of salmonid populations. 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.

About this title

Synopsis

Explore how juvenile salmonids inhabit a major reservoir and what that means for passage and management.

This study maps where young fish are found across horizontal areas and different depths, revealing patterns that could affect collection and passage strategies in reservoir systems. This edition focuses on a real-world reservoir on the Cowlitz River, detailing how researchers sampled fish with gill nets and a trawl, what species were present, and how environmental factors like depth and turbidity influenced catches. It also explains the approach to comparing sampling methods and interpreting movement past a fixed site, with practical notes on data collection and analysis.

• How vertical and horizontal distribution of juvenile salmonids was measured
• Which species were most common and how size affected net capture
• Sampling design, stations, and how depth and time influenced results
• Implications for fish passage, collection sites, and reservoir management

Ideal for readers of fisheries research and field studies seeking practical insight into reservoir fish distribution and management considerations.
