Book Description
This volume focuses on the US-Canadian experience with the shared fishery resources of the Laurentian Great Lakes, a vast and complex ecosystem that holds 20 percent of the world's surface fresh water supply and a wide array of fish and fisheries. Written by scientists from federal, state, and provincial management agencies, contributions address current knowledge of the ecological, sociological, and policy issues that face the region's fishery managers and policy makers in both countries. Lacks a subject index.

Book Description
Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.

Book Description
Lake trout (Salvelnus namaycush) were the dominant coldwater predator in Lake Huron until population crashes occurred in the 1940s and 1950s. Since that time, international rehabilitation efforts directed at lake trout have been implemented. To further lake trout rehabilitation efforts in Ontario waters of Lake Huron, the Ontario Ministry of Natural Resources drafted the 1996 Lake Trout Rehabilitation Plan for Lake Huron (Canadian jurisdiction) using the continuum concept for guidance. Using the 1996 Plan objectives and evaluation criteria as benchmarks, progress towards rehabilitation in each of the 16 Lake Trout Rehabilitation Zones (LTRZs) is described. Upon review, the intent of the goal and objectives from the 1996 plan were deemed to be sound. However, revisions to the three objectives have been recommended that more closely relate them to the progression through rehabilitation. These revised objectives more closely reflect timelines associated with rehabilitation, and how these timelines differ between individual LTRZs as a result of differences in stocking history, stocking density, total annual mortality, and age to maturity. In addition to recommendations specific to the goals and objectives, recommendations for changes to rehabilitation strategies (i.e. stocking and exploitation control), evaluation criteria, and assessment tactics are made.--Document.

Book Description
Continuing concern about water supply and quality, ecosystem sustainability and restoration demands that the modern approach to the management of lakes and reservoirs should be based on a sound understanding of the application of the scientific and ecological principles that underlie freshwater processes. The Lakes Handbook provides an up-to-date overview of the application of ecologically sound approaches, methods and tools using experience gained around the world for an understanding of lakes and their management. Volume one of the Handbook addresses the physical and biological aspects of lakes pertinent to lake management, emphasising those aspects particularly relevant to large, still bodies of water. Volume two then considers lake management, with particular emphasis on sustainability, restoration and rehabilitation. This handbook will be invaluable to ecologists, environmental scientists, physical geographers and hydrologists involved in limnological research, as well as advanced undergraduate and graduate students looking for authoritative reviews of the key areas of limnological study.
