Download or read book Ecology and Management of Atlantic Salmon written by D. Mills and published by Springer Science & Business Media. This book was released on 1989-01-31 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reviews advances in the understanding of the biology, ecology and management of the Atlantic salmon throughout its geographical range, and examines the effects on salmon of afforestation, pollution, acid rain, water abstraction and changing agricultural methods. The rapid escalation of salmon farming with its impact on wild stocks is analyzed as is the increasing threat of over-exploitation on both the open seas and in home waters.

Download or read book Effects of Water Temperature and Angling on Mortality of Salmonids in Montana Streams written by James W. Boyd and published by . This book was released on 2008 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Montana, angling closures are used to protect salmonids from the deleterious impacts of angling at elevated water temperatures (23°C). Catch-and-release angling (CR) studies have reported high levels (30-40%) of salmonid mortality at water temperatures>20°C, but few studies assess CR mortality of salmonids at water temperatures observed in Montana streams during mid-summer (23°C). The primary objective of this study was to measure CR mortality of rainbow trout, brown trout, and mountain whitefish in three water temperature treatments; when daily maximum water temperatures were cool (20°C), warm (20 to 22.9°C), and hot (23°C). A secondary objective was to assess CR mortality of salmonids angled in morning and evening within water temperature treatments. Based on the literature, mortality of salmonids was predicted to be30% within the hot treatment and higher in evening than morning. Angling (fly-fishing only) occurred in the Gallatin and Smith rivers. All angled fish were confined to in-stream holding cages and monitored for mortality for 72 h. Mortality of rainbow trout Oncorhynchus mykiss increased to 9% and 16% in warm and hot treatments, respectively. Mortality of brown trout Salmo trutta was (4%) in the hot treatment in the Smith River. Mountain whitefish Prosopium williamsoni had increased mortality in the warm (20%) and hot (28%) treatments in the Smith River. No mortality for any species occurred in either river when water temperatures were 20°C. Mortality of rainbow trout angled in evening was higher than morning in the warm (14%) and hot (16%) treatments in the Smith River. Laboratory results indicated rainbow trout stressed in evening had higher mortality (7%) than those stressed in morning (0%). Angler catch rates were lower for most species in evening than morning angling events; however, catch rates remained high (0.7 fish/h) in several evening angling events. Study results indicate that salmonid mortality rates associated with catch-and-release fly-fishing are higher at elevated (or equal to 23°C) water temperatures. Although there was a relationship between elevated water temperature and salmonid mortality, most of the mortality estimates were well below the 30% mortality that was predicted.

Book excerpt: The Atlantic Salmon: Moody and Mysterious examines Atlantic salmon behavior and angling approaches as developed through the eyes and mind of expert angler Jim Lorentz . The theories and conclusions discussed in the book are the result of the author spending nearly every day of the late spring, summer and early autumn riveted to a salmon river. Many of the strategies and techniques discussed are new to Atlantic salmon fly fishing and challenge many of the ideas that have been considered standard practice for this species.

Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
