“Eels [is] more than a fish book. It is an impassioned defense of nature itself. . . . [Prosek] passes on the truth that the often disdained eel, like all migratory fish, is vital and mysterious and worthy of our full effort to bring it back.” — New York Times Book Review “A wonderful account of far-flung travels in pursuit of the secrets of the earth’s most mysterious fish. . . . Fascinating and beautifully rendered.” — Peter Matthiessen Famous for his deeply informed, compulsively readable books on trout, James Prosek (whom the New York Times has called “the Audubon of the fishing world”) takes on nature’s quirkiest and most enigmatic fish: the eel. Fans of Mark Kurlansky’s Cod and The Big Oyster or Trevor Corson’s The Secret Life of Lobsters will love Prosek’s probing exploration of the hidden deep-water dwellers. With characteristically captivating prose and lavish illustrations, Prosek demystifies the eel’s unique biology and bizarre mating routines, and illuminates the animal’s varied roles in the folklore, cuisine, and commerce of a variety of cultures.

Competition has played a large role in structuring natural communities, especially with regards to vulnerable organisms. Brook trout and American eel populations have declined in the Mid-Atlantic Region of the United States as a result of anthropogenic development around freshwater ecosystems, and thus, subsequent conservation efforts of both species have included habitat restoration. Conservation efforts have increased the co-occurrence of these predatory fish species that are known to require similar resources. The main objective of this research was to elucidate the potential for competition between brook trout and American eels through analysis of their preferred prey, diet overlap, and supplementary attributes of the respective fish and invertebrate populations. Over three sampling intervals in the summer of 2017, a reach of stream above Crabtree Falls in Nelson County, Virginia, acted as the control, where only brook trout are present, and a reach of stream below the same waterfall acted as the treatment, trout and eels present. Brook trout abundance was 140 fish per 100 m of stream above and 117 per 100 m below the falls, but size and body condition did not differ significantly between samples reaches, nor did size and body condition of the current year class. Both fish species had low rates of empty stomachs (7-8%) and there was zero observed predation on brook trout by eels. The efficiency of gastric lavage for American eels was determined to be 89% by number of prey items, but biased towards smaller prey size. Over the course of the study brook trout mostly preferred terrestrial invertebrates of the 12 available prey groups with no significant difference in diet where they co-occurred with eels, and eels preferred crayfish. Diet overlap between trout and eels below the falls was 73% overall; however, this does not directly indicate competition. Invertebrate communities had lower abundance below the falls, but both sample reaches had similar diversity, and there was no significant difference between invertebrate communities overall. As conservation efforts increase the co-occurrence of brook trout and American eels, there is limited potential for competition as demonstrated by the parameters examined in this regionally novel study.

Fish form an extremely diverse group of vertebrates. At a conservative estimate at least 40% of the world's vertebrates are fish. On the one hand they are united by their adaptations to an aquatic environment and on the other they show a variety of adaptations to differing environmental conditions - often to extremes of temperature, salinity, oxygen level and water chemistry. They exhibit an array of behavioural and reproductive systems. Interesting in their own right, this suite of adaptive physiologies provides many model systems for both comparative vertebrate and human physiologists. This four volume encyclopedia covers the diversity of fish physiology in over 300 articles and provides entry level information for students and summary overviews for researchers alike. Broadly organised into four themes, articles cover Functional, Thematic, and Phylogenetic Physiology, and Fish Genomics. Functional articles address the traditional aspects of fish physiology that are common to all areas of vertebrate physiology including: Reproduction, Respiration, Neural (Sensory, Central, Effector), Endocrinology, Renal, Cardiovascular, Acid-base Balance, Osmoregulation, Ionoregulation, Digestion, Metabolism, Locomotion, and so on. Thematic Physiology articles are carefully selected and fewer in number. They provide a level of integration that goes beyond the coverage in the Functional Physiology topics and include discussions of Toxicology, Air-breathing, Migrations, Temperature, Endothermy, etc. Phylogenetic Physiology articles bring together information that bridges the physiology of certain groupings of fishes where the knowledge base has a sufficient depth and breadth and include articles on Ancient Fishes, Tunas, Sharks, etc. Genomics articles describe the underlying genetic component of fish physiology and high light their suitability and use as model organisms for the study of disease, stress and physiological adaptations and reactions to external conditions. Winner of a 2011 PROSE Award Honorable Mention for Multivolume Science Reference from the Association of American Publishers The definitive encyclopedia for the field of fish physiology Three volumes which comprehensively cover the entire field in over 300 entries written by experts Detailed coverage of basic functional physiology of fishes, physiological themes in fish biology and comparative physiology amongst taxonomic Groups Describes the genomic bases of fish physiology and biology and the use of fish as model organisms in human physiological research Includes a glossary of terms

Literary Nonfiction. Essays. GHOST TROUT is a series of narratives and essays that chronicle the search for the rare Humboldt cutthroat trout, and rivers and streams and their relationship to people and birds and dogs and the human condition. Pieces of the past are mingled with lives and deaths and a long-ago memory of a dance performed by the daughter of the California poet, Joaquin Miller. "GHOST TROUT is more than a collection of essays--it's a glimpse into what makes us tick."--Green Apple Books, San Francisco "Another marvelous collection, this one filled with tiny explosions of narration and exposition. A book you'll keep picking up to find something new that touches on your life."--Don Christians (KWMR FM radio) "Like a canvas that is painted with precise strokes, this set of narrative moments freezes your attention on universal images."--Russell Chatham

The study of fish neuroendocrinology has had a significant impact on our general understanding of the functional roles and evolution of a variety of neurochemical messengers and systems. Not only do fish possess unique neuroendocrine features, they have also been and remain an important vertebrate models for the discovery of new neuropeptides. In the last fifty years, neuroendocrinologists have documented a complex and seemingly infinite number of interactions between hormones and nerve structures. Gradually emerging from this knowledge is an understanding of the specific neurohormonal pathways and the messengers responsible for maintaining homeostasis in an aquatic environment and for regulating the functional systems that allow for the highly diverse life histories and reproductive tactics of fish Despite its recent growth, breadth and unique attributes, there is no single text covering the discipline of fish neuroendocrinology. In fact, other than a few mammalian neuroendocrinology textbooks, there is a serious lack of texts in comparative neuroendocrinology. Currently, information on the anatomical organization and function of the various neuroendocrine systems in fish is only available in original research papers and reviews. By providing a current and comprehensive volume that highlights the specific properties of fish neuroendocrinology, this book will go beyond being the only reference text for fish neuroendocrinologists and will also serve comparative physiologists, endocrinologists, neuroanatomists and behaviourists interested in understanding the reciprocal actions between the nervous and endocrine systems. Highlights the specific properties of fish neuroendocrinology Emphasises the range and variety of interactions between neurobiology and endocrinology Discuses both anatomical and functional aspects of the Neuroendocrine system Also serves comparative physiologists, endocrinologists, neuroanatomists and behaviourists interested in understanding the reciprocal actions between the nervous and endocrine systems
