Book Description
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.

Book Description
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.

Category : Science
Languages : en
Pages : 446

Book Description
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.

Languages : en
Pages : 727

Book Description
A comprehensive, lavishly illustrated guide to tying popular trout flies. This book is aimed at all fly tyers, from those with modest experience to those with more advanced skills. The author’s intention is to focus on certain important elementary techniques, and then share some of his favorite contemporary twists on old, tried-and-true techniques. Many of the flies in this book are based in his own techniques and patterns, ones that he has developed in more than thirty-five years of tying. The book is arranged in sections to give readers the opportunity to easily locate the pattern or technique they are looking for. Patterns are not grouped alphabetically, but by technique. For example, the section on dry flies has categories demonstrating a particular dry fly style or technique such as mastering the use of deer hair, parachute, CDC, and so on. If you are fairly new to fly tying, the opening chapters on materials and special techniques and tricks will familiarize you with some basics and help you get started. Seasoned tyers will similarly find information here to help them raise their tying skills to a new level. Each pattern is listed with a recipe, recommended hook style, size, and materials. They are listed in the order that that author uses them, and illustrated by the book’s step-by-step images. This will help you plan each pattern and assemble materials your beforehand. Included are lushly illustrated photos for such well-known trout flies as: Pheasant tail nymph Klinkhamer Humpy Deer Hair Irresistible CDC Mayfly Spinner And much more. A special feature of this one-of-a-kind books is that its the first tying book to have a video link for all the patterns featured. Watch the author tying online, then turn to the matching chapter in the book to follow the step-by-step instructions so that you can tie your own fly in your own time. Author Barry Ord Clarke will respond online to your questions.

Fish and Diadromy in Europe (ecology, management, conservation)

Fish and Diadromy in Europe (ecology, management, conservation) PDF Author: Sylvie Dufour
Publisher: Springer Science & Business Media
ISBN: 1402085486
Category : Science
Languages : en
Pages : 185

Book Description
Most of the diadromous fish of the world have decreased in distribution and abundance since the beginning of the twentieth century. They are now threatened, and important conservation issues arise. The causes of these trends vary among species and basins but regional human impact (damming, pollution, fisheries) and global change (climate) are suspected to be responsible for these difficulties. This book contains selected papers from an international symposium organised by the Diadfish network held in Bordeaux (France) in 2005. Readers will find up-to-date information on the ecology, ecotoxicology and physiology of several diadromous species (Atlantic salmon, shads, lampreys, eels) and this whole group in Europe. Main impacts are also documented and analysed in case studies, and solutions or remediation actions are presented.

Eels Biology, Monitoring, Management, Culture and Exploitation: Proceedings of the First International Eel Science Symposium

Eels Biology, Monitoring, Management, Culture and Exploitation: Proceedings of the First International Eel Science Symposium PDF Author: Andy Don
Publisher: 5m Books Ltd
ISBN: 1789181127
Category : Technology & Engineering
Languages : en
Pages : 551

Book Description
The freshwater eels, the Anguillids, have increasingly become the focus of attention for fisheries managers, scientists, researchers, policy makers, conservation bodies and other stakeholders. These species can be seen as a bellwether for issues affecting aquatic ecosystems – their steep decline and the management initiatives to try and reverse this trend, touch on subjects as diverse as disconnected waterways, loss of habitat, novel parasites, pollution, over-fishing and climate change. There are some 16 species of the Anguilla genus and all exhibit similar lifestyles, growing in waters often far-removed from their marine spawning grounds. These enigmatic, contradictory and confounding species share similar challenges and pressures wherever they are found. This book was generated from the 1st UK International Eel Science Symposium which was held at the Zoological Society of London (ZSL) in June 2017. Hosted by the Institute of Fisheries Management (IFM), the ZSL, and the Environment Agency (EA), the Symposium was heralded as a success, with over 180 delegates in attendance. Many of the world’s top eel specialists attended or gave presentations across a diverse range of subjects. This was one of the Symposium’s, and now the book’s great strengths – its diversity of subjects and authors. Many countries are represented within the book, from across Europe and as far afield as New Zealand, South Africa, Vanuatu, French Polynesia, Japan, Canada and the USA. The EA and IFM have collaborated to produce this landmark book which includes a mix of cultural, scientific and management information which will be invaluable to anyone with a professional or personal interest in these mysterious fish, including ichthyologists, fisheries scientists and managers, aquaculture personnel, environmental biologists and ecologists, marine and freshwater biologists, vertebrate zoologists, animal behaviourists and students studying in all these areas. Libraries in all universities and research establishments where these subjects are studied and taught should have copies on their shelves. 5m Books
