Book Description
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.

Book Description
This manual for the identification of larval fishes of the Great Lakes basin with emphasis on the Lake Michigan drainage treats 24 families and 148 species. In addition to a key to the families, keys were constructed for selected species within some families. Species accounts include descriptions of adult ecology, reproductive biology, diagnostic characters and meristics. A description of the egg is given, as are morphometric, morphological and pigmentation characteristics of yolk-sac larvae, larvae and juveniles. Illustrations of yolk-sac larvae, larvae and juveniles have been included wherever possible and informative.
Inland Fishes of California

Book Description
When the first edition of Inland Fishes of California was published in 1976, it was a benchmark reference. Since that time, our knowledge of California's freshwater fishes has dramatically increased. This completely revised edition incorporates a vast amount of new information and creates a fresh synthesis of the historical data. Written by the leading expert on California's freshwater fishes and illustrated with beautiful line drawings, this compendium is the single best source for understanding and identifying the state's freshwater fishes. It is an essential resource for anyone who needs to have accurate and detailed information on California's fishes at their fingertips. Since the 1870s, the state's native fishes have been joined by thirty-four alien species, which now dominate many bodies of water. This book treats both native and introduced species, first in a key for identification, and then in individual species accounts covering characteristics, taxonomy, names, distribution, and life history. Each account includes the author's personal assessment of how well the species is doing and problems associated with its management. Most of the native fishes are found only in California and show many wonderful adaptations for living in the state's diverse waters. Unfortunately, many are also in danger of extinction. The message underlying the first edition of this book was that we knew astonishingly little about many of California's inland fishes. Although our knowledge is increasing, full accounts of some native fishes may not be complete before they become extinct. Preventing the loss of native fishes is the major goal of this book, and Moyle makes important suggestions for conservation strategies as well as presenting up-to-date information on ecology, life history, and distribution. With this knowledge, preserving our native fishes becomes possible even in the face of the state's growing economy and population.
