This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rehabilitation of lake trout (Salvelinus namaycush), which historically was the coldwater apex predator of much of the Laurentian Great Lakes, is a priority for fishery management agencies in the region. In Lake Erie, the shallowest and southern-most Great Lake, successful rehabilitation of lake trout has been hindered by limited wild recruitment, possibly related to the lake's warm temperatures and restricted oxythermal habitat. I used acoustic telemetry tracking technology to investigate how lake trout spatial and thermal habitat use varies seasonally in Lake Erie to better understand whether limited recruitment could be caused by thermal conditions in the lake. As expected, lake trout were restricted to the offshore region of the eastern basin of Lake Erie during summer stratification. During fall, lake trout tended to occupy the southern nearshore region of the eastern basin, suggesting the importance of focusing spawning habitat restoration in this part of the lake. Tagged fish dispersed long distances at much higher frequencies than other Great Lakes populations of lake trout. Lake trout in Lake Erie occupied thermal habitat similar to other Great Lakes populations during summer stratification. Following destratification in fall, fish were exposed to warm temperatures, in some years for extended periods. Lake trout hatchery strains of Finger Lakes, NY, origin occupied similar summer temperatures and warm temperatures for more days during fall than Great Lakes origin strains, contrary to findings from Lakes Huron and Ontario. These results reveal behaviors that can inform management of lake trout in Lake Erie and throughout the Great Lakes and could begin to explain recruitment failure observed in Lake Erie.

Download or read book The Lake Charr Salvelinus namaycush Biology Ecology Distribution and Management written by Andrew M. Muir and published by Springer Nature. This book was released on 2021-03-03 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lake charr Salvelinus namaycush is a ubiquitous member of cold-water lake ecosystems in previously glaciated regions of northern continental U.S., Alaska, and Canada that often support important commercial, recreational, and subsistence fisheries. The lake charr differs from other charrs by its large size, longevity, iteroparity, top-predator specialization, reduced sexual dimorphism, prevalence of lacustrine spawning, and use of deepwater habitat. The species is remarkably variable in phenotype, physiology, and life history, some of which is reflected in its ecology and genetics, with as many as four morphs or ecotypes co-occurring in a single lake. The lake charr is often the top predator in these systems, but is highly adaptable trophically, and is frequently planktivorous in small lakes. The lake charr by their name highlights their common habitat, lakes both large and small, but often frequents rivers and occasionally moves into the Arctic Ocean. Movement and behaviour of lake charr are motivated by access to cool, well-oxygenated water, foraging opportunities, predator avoidance, and reproduction. Owing to their broad distribution and trophic level, the lake charr serves as a sentinel of anthropogenic change. This volume will provide an up-to-date summary of what is currently known about lake charr from distribution to genetics to physiology to ecology. The book provides a compilation and synthesis of available information on the lake charr, beginning with an updated distribution and a revised treatment of the paleoecology of the species. Understanding of ecological and genetic diversity and movement and behaviour of the species has advanced remarkably since the last major synthesis on the species over 40 years ago. Mid-sections of the book provide detailed accounts of the biology and life history of the species, and later sections are devoted to threats to conservation and fishery management practices used to ensure sustainability. A new standard lake charr-specific terminology is also presented. The book will be a valuable reference text for biologists around the world, ecologists, and fishery managers, and of interest to the angling public.

Available in PDF, EPUB and Kindle. Book excerpt: New York Times Bestseller Winner of the Los Angeles Times Book Prize Winner of the J. Anthony Lukas Award "Nimbly splices together history, science, reporting and personal experiences into a taut and cautiously hopeful narrative.… Egan’s book is bursting with life (and yes, death)." —Robert Moor, New York Times Book Review The Great Lakes—Erie, Huron, Michigan, Ontario, and Superior—hold 20 percent of the world’s supply of surface fresh water and provide sustenance, work, and recreation for tens of millions of Americans. But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

This book was released on 1990 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native stocks of lake trout were severely depleted in much of Lake Superior and became virtually extinct in Lakes Michigan, Huron, Erie and Ontario during the 1940-50s. The Great Lakes Fisheries Commission has developed a series of 7 goals for Lake Superior, one of which was the restored use of historical spawning reefs by lake trout. This assumed an ability to identify characteristics of spawning locations. To determine common factors among spawning sites, published material of lake trout spawning in the Great Lakes was reviewed and spawning sites were identified and enumerated, depth and substrate characteristics were summarized, and information sources were evaluated.
