In the 20 years since publication of the first edition, the number of freshwater fish species has risen by almost 150. This second edition incorporates all of these new species, plus all-new maps and a collection of new and revised plates.

There are more than 33,000 species of living fishes, accounting for more than half of the extant vertebrate diversity on Earth. This unique and comprehensive reference showcases the basic anatomy and diversity of all 82 orders of fishes and more than 150 of the most commonly encountered families, focusing on their distinctive features. Accurate identification of each group, including its distinguishing characteristics, is supported with clear photographs of preserved specimens, primarily from the archives of the Marine Vertebrate Collection at Scripps Institution of Oceanography. This diagnostic information is supplemented by radiographs, additional illustrations of particularly diverse lineages, and key references and ecological information for each group. An ideal companion to primary ichthyology texts, Fishes: A Guide to Their Diversity gives a broad overview of fish morphology arranged in a modern classification system for students, fisheries scientists, marine biologists, vertebrate zoologists, and everyday naturalists. This survey of the most speciose group of vertebrates on Earth will expand the appreciation of and interest in the amazing diversity of fishes.

NATURE-STUDY is, despite all discussions and perversions, a study of nature; it consists of simple, truthful observations that may, like beads on a string, finally be threaded upon the understanding and thus held together as a logical and harmonious whole. Therefore, the object of the nature-study teacher should be to cultivate in the children powers of accurate observation and to build up within them, understanding. FIRST, but not most important, nature-study gives the child practical and helpful knowledge. It makes him familiar with nature’s ways and forces, so that he is not so helpless in the presence of natural misfortune and disasters. Nature-study cultivates the child’s imagination since there are so many wonderful and true stories that he may read with his own eyes, which affect his imagination as much as does fairy lore; at the same time nature-study cultivates in him a perception and a regard for what is true, and the power to express it. All things seem possible in nature; yet this seeming is always guarded by the eager quest of what is true. Perhaps, half the falsehood in the world is due to lack of power to detect the truth and to express it. Nature-study aids both in discernment and expression of things as they are. Nature-study cultivates in the child a love of the beautiful; it brings to him early a perception of color, form and music. He sees whatever there is in his environment, whether it be the thunder-head piled up in the western sky, or the golden flash of the oriole in the elm; whether it be the purple of the shadows on the snow, or the azure glint on the wing of the little butterfly. Also, what there is of sound, he hears; he reads the music score of the bird orchestra, separating each part and knowing which bird sings it. And the patter of the rain, the gurgle of the brook, the sighing of the wind in the pine, he notes and loves and becomes enriched thereby. But, more than all, nature-study gives the child a sense of companionship with life out of doors and an abiding love of nature. Let this latter be the teacher’s criterion for judging his or her work. If nature-study as taught does not make the child love nature and the out-of-doors, then it should cease. Let us not inflict permanent injury on the child by turning him away from nature instead of toward it. However, if the love of nature is in the teacher’s heart, there is no danger; such a teacher, no matter by what method, takes the child gently by the hand and walks with him in paths that lead to the seeing and comprehending of what he may find beneath his feet or above his head. And these paths whether they lead among the lowliest plants, or whether to the stars, finally converge and bring the wanderer to that serene peace and hopeful faith that is the sure inheritance of all those who realize fully that they are working units of this wonderful universe.

The deluxe, comprehensive guide to the native species of Mississippi Download Plain Text version Where was the largest bass caught in Mississippi? What streams are sometimes home to the gulf sturgeon? How can an angler tell a grass pickerel from a walleye? In Inland Fishes of Mississippi, Stephen T. Ross answers these questions and many more. Mississippi waters are some of the richest inland fish habitats in the United States. In fact, only four states have more native fish than Mississippi's 204. Inland Fishes of Mississippi is for anglers and nature lovers who want to learn more about this thriving diversity. Introductory chapters present the history of the study of fish in Mississippi, the distribution patterns of species, important conservation issues, and valuable information on identifying fish by examining body shape and structure. Following these are illustrated keys to all the families of fish known to inhabit inland waters. Each key is a detailed guide to identifying the specific species within a family of fish. Keys include: color photographs of freshly collected examples meanings of scientific names for fish descriptions of color and physical changes maximum sizes of fish, including records for game fish precise maps of distribution vital information on habitat requirements, feeding, and behavior tips on where to catch a species status of conservation efforts For both the casual angler and the ichthyologist, Inland Fishes of Mississippi will prove a constant resource and an irreplaceable asset for identifying, observing, and catching the state's various species. Stephen T. Ross is professor of biological sciences and Curator of Fishes at the University of Southern Mississippi. The editor for ecology and ethology of Copeia, he has also published articles in numerous journals such as American Naturalist, Environmental Biology of Fishes, and Transactions of the American Fisheries Society.

At least 162 species of fish are known to live or spawn in the freshwaters of the Northeast, representing twenty-eight families and sixteen orders. This diversity springs from an enormous variety of freshwater habitats, including some of the largest lakes in the world; vast and complex river systems; deep, clear lakes in Maine and the Adirondack Mountains; and myriad small lakes, bogs, marshes, and streams that dot the northeast. In the most comprehensive book of its kind, Robert G. Werner offers a thorough survey and analysis, in accessible field guide form, of the region’s abundant freshwater fishes. Werner’s discussion of the geological history of the region serves as a critical background for understanding not only the fascinating habitats of fishes but also the extensive watersheds and drainages of the region. A reference list provides up-to-date sources, and the species descriptions contain the latest relevant data and research on specific fish. In addition, vivid color plates and extensive line drawings illustrate fish morphology and the distinctive natural colors of numerous species. As a standard resource, this guide will attract a wide audience. This book will be useful to biologists, ecologists, and zoologists and will have an indispensable appeal among anglers, environmentalists, and fisheries professionals.
