Download or read book The Eel written by F. Tesch and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: by Dr P .H. Greenwood British Museum (Natural History), London Dr Tesch's wide ranging account of anguillid eels impinges on the interests of many biologists; it is not simply a specialized tome narrowly aimed at ichthyologists and fishery scientists, rather it provides a source of primary reference and a comprehensive sununary of informa tion that is not likely to be superseded for a long time. It is significant that the bibliography includes references to learned journals concerned with physiology, pharmacology, taxonomy, genetics, zoology, endo crinology, botany, ecology and environmental interactions. Such is the breadth of interest in the Anguillidae. Few fish species have been subjected to as detailed review as Dr Tesch gives for the (wo Atlantic species of Anguilla. An equally comprehensive resume of research into the fourteen, rather less well-studied Indo Pacific species gives balance and reciprocal illumination to several biological problems posed by these similar but quite distinctive species.
Download or read book Eel Biology written by K. Aida and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a food resource in both Eastern and Western countries, the eel is an important fish. Over the years, remarkable progress has been achieved in understanding the mysterious life cycle of eels that has fascinated scientists since the age of Aristotle. The spawning area of the Japanese eel was discovered and the migratory route of its larvae was elucidated. With the development of techniques for artificial induction of gonadal maturation, it became possible to obtain hatched larvae. Larval rearing to the leptocephalus stage, one of the most difficult tasks involved in eel culture, finally was achieved. By presenting these important breakthroughs, Eel Biology will be of great help in the development of effective management strategies for maintaining stable eel populations. With contributions by leading experts, this book is a valuable source for researchers as well as industry technicians in the fields of aquatic biology, aquaculture, and fisheries.
Download or read book Eels and Humans written by Katsumi Tsukamoto and published by Springer Science & Business Media. This book was released on 2013-10-29 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains much of what is known currently about freshwater eels, focusing on social and cultural aspects as well as science. A wealth of eel-related material is presented by scientists from around the world, including information on eel fishing, resources, distribution, aquaculture, economics, cuisine, environment and ecosystems, idioms, arts and crafts, tradition, legends, mythology, archaeology and even memorial services. Eels are important as food for humankind and are an interesting model for scientists studying animal migration and reproductive ecology. Their snake-like morphology differentiates them from most other fish, and their unpredictable behaviour that allows them to move over wet land and climb rocks adjacent to waterfalls attracts attention and evokes curiosity. Eels are therefore considered to be enigmatic creatures or metaphysical entities beyond human intelligence; indeed, they have been deified in parts of the world. In recent decades, however, with global populations of eels in sharp decline, some species face a real threat of extinction, and effective conservation strategies and measures are needed. Comparisons across these issues between various countries provide an image of a long-lasting relationship between eels and humankind, and encourage comprehensive and detailed understanding of eels from the perspectives of social, cultural and natural sciences. By promoting understanding of the close relationship between eels and humans, the broader public is engaged and public awareness of eel importance raised, helping to conserve these unique but endangered fish.

Download or read book Eel written by Richard Schweid and published by Reaktion Books. This book was released on 2009-05-15 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: When pulled from the mud of creeks, ponds, rivers, or the sea, the eel, with its slick, snake-like body, emerges as an extremely mundane and even unappealing fish. But don’t let the appearance fool you—the eel has been one of the world’s favorite foods since ancient Greece, and the eel’s life cycle is one of the most remarkable on the planet—during the middle ages, impoverished Londoners survived on eel and the eel later saved the Mayflower pilgrims from starvation on American shores. In Eel, RichardSchweid chronicles the many facets of these slippery creatures from their natural history to their market value and contemporary consumption to their appearance in art and literature and finally to their present threatened status. So far, eels have steadfastly refused to reproduce in captivity, apparently requiring the vastness of the open ocean to successfully mature—which has imperiled the species’ long-term survival. Schweid explains that freshwater eels are born in remote ocean depths and make a journey of thousands of miles to fresh water where they spend most of their lives before making a return journey to the ocean to mate and die. Well-illustrated and containing many little-known facts about this surprising fish, Eel will appeal to general readers of natural history and others wishing to discover something more about the common unagi on the sushi menu.

Book excerpt: A Finalist for the Los Angeles Times Book Prize National Bestseller Winner of the National Outdoor Book Award Longlisted for the Andrew Carnegie Medal for Excellence in Nonfiction A New York Times Notable Book One of TIME’s 100 Must Read Books of the Year One of The Washington Post’s 50 Notable Nonfiction Books of the Year One of Smithsonian Magazine’s 10 Best Science Books of the Year One of Publishers Weekly’s Best Nonfiction Books of the Year A New York Times Editor’s Choice Part H Is for Hawk, part The Soul of an Octopus, The Book of Eels is both a meditation on the world’s most elusive fish—the eel—and a reflection on the human condition Remarkably little is known about the European eel, Anguilla anguilla. So little, in fact, that scientists and philosophers have, for centuries, been obsessed with what has become known as the “eel question”: Where do eels come from? What are they? Are they fish or some other kind of creature altogether? Even today, in an age of advanced science, no one has ever seen eels mating or giving birth, and we still don’t understand what drives them, after living for decades in freshwater, to swim great distances back to the ocean at the end of their lives. They remain a mystery. Drawing on a breadth of research about eels in literature, history, and modern marine biology, as well as his own experience fishing for eels with his father, Patrik Svensson crafts a mesmerizing portrait of an unusual, utterly misunderstood, and completely captivating animal. In The Book of Eels, we meet renowned historical thinkers, from Aristotle to Sigmund Freud to Rachel Carson, for whom the eel was a singular obsession. And we meet the scientists who spearheaded the search for the eel’s point of origin, including Danish marine biologist Johannes Schmidt, who led research efforts in the early twentieth century, catching thousands upon thousands of eels, in the hopes of proving their birthing grounds in the Sargasso Sea. Blending memoir and nature writing at its best, Svensson’s journey to understand the eel becomes an exploration of the human condition that delves into overarching issues about our roots and destiny, both as humans and as animals, and, ultimately, how to handle the biggest question of all: death. The result is a gripping and slippery narrative that will surprise and enchant.
