Available in PDF, EPUB and Kindle. Book excerpt: The relation of field polarity to fish guiding effectiveness was tested under controlled laboratory conditions by using a single-row electrode array sequentially energized so that: (1) positive polarity was always toward the upstream end, (2) positive polarity was always toward the downstream end, and (3) polarity alternated to cancel out polarity orientation. No difference in effectiveness was found demonstrating that fish guiding was due to avoidance rather than to electrotaxis. Variability, measured as variance, decreased as sample size increased but the mean effectiveness was similar for fish release lots of 15, 50, and 100 fish each.

Download or read book Power Plants written by Charles Hocutt and published by Elsevier. This book was released on 2012-12-02 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power Plants: Effects on Fish and Shellfish Behavior reviews the effects of power plant construction, operation, and maintenance on the behavior of fish and important shellfish populations such as blue crabs, crayfish, lobsters, penaeid shrimp, and bivalve molluscs. The emphasis is on the link between power plant design and fish aggregation phenomena. The effects of biocides and temperature on fish behavior are also examined. This book is comprised of 13 chapters and begins with a discussion on the economic relevance of power plants and their environmental impact on fish and shellfish populations. The potential of power generating facilities to act as a physical stimulus for fish aggregation is then considered. The effect of parameters associated with power plants, such as temperature and biocides, on fish behavior is the subject of subsequent chapters. The ecological and behavioral characteristics influencing entrainment of fish eggs and young at cooling water intakes are analyzed. This monograph is oriented to those involved in assessment of power plants on aquatic communities, including consultants, state and federal regulators, and electrical utility personnel, as well as researchers in physiology, ecology, and ethology.

This book was released on 2016-09-26 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Effect of Field Polarity in Guiding Salmon Fingerlings by Electricity The major objectives of the tests described here were to determine whether reactions of the fish are caused by avoid ance or by electrotaxis, and if the latter, to determine whether an upstream or down stream field polarity orientation is more effective.
