Ellen Ruppel Shell's Slippery Beast is a fascinating account of a deeply mysterious creature—the eel—a thrilling saga of true crime, natural history, travel, and big business. What is it about eels? Depending on who you ask, they are a pest, a fascination, a threat, a pot of gold. What they are not is predictable. Eels emerged some 200 million years ago, weathered mass extinctions and continental shifts, and were once among the world's most abundant freshwater fish. But since the 1970s, their numbers have plummeted. Because eels—as unagi—are another thing: delicious. In Slippery Beast, journalist Ellen Ruppel Shell travels in the world of “eel people,” pursuing a burgeoning fascination with this mysterious and highly coveted creature. Despite centuries of study by celebrated thinkers from Aristotle to Leeuwenhoek to a young Sigmund Freud, much about eels remains unknown, including exactly how eels beget other eels. Eels cannot be bred reliably in captivity, and as a result, infant eels are unbelievably valuable. A pound of the tiny, translucent, bug-eyed “elvers” caught in the cold fresh waters of Maine can command $3,000 or more on the black market. Illegal trade in eels is an international scandal measured in billions of dollars every year. In Maine, federal investigators have risked their lives to bust poaching rings, including the notorious half-decade-long “Operation Broken Glass.” Ruppel Shell follows the elusive eel from Maine to the Sargasso Sea and back, stalking riversides, fishing holes, laboratories, restaurants, courtrooms, and America's first commercial eel “family farm,” which just might upend the international market and save a state. This is an enthralling, globe-spanning look at an animal that you may never come to love, but which will never fail to astonish you, a miraculous creature that tells more about us than we can ever know about it.

This book is a compilation of eel research and fish migration studies for more than 40 years showing the research history and recent advances in eel studies. Dr. Katsumi Tsukamoto, the esteemed editor of this book, has been actively involved in eel research as one of the leading scientists in the world for a long time, and he and his team successfully collected the fertilized eggs and spawn-condition adult eels from the wild for the first time in the world. This book compiles the essentials of the scientific findings obtained by the editor and his colleagues and reviews the latest references of eel science. Knowledge and information in the book such as a spawning area survey, research on artificial production of glass eels, the discovery of a new species, etc. will attract the reader's interest, as these are written based on the authors'experiences. Readers can obtain a comprehensive understanding of eels from various aspects of eel science including the cultural and socio-economic importance of eels and valuable scientific information using state-of-the-art approaches. The book also endeavors to contribute to the conservation of eel species, some of which have been classified as endangered by the IUCN and to promoting harmonious coexistence between humans and nature.

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 conditionRemarkably 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.A Finalist for the Los Angeles Times Book PrizeNational BestsellerWinner of the National Outdoor Book AwardLonglisted for the Andrew Carnegie Medal for Excellence in NonfictionA New York Times Notable BookOne of TIME's 100 Must Read Books of the YearOne of The Washington Post's 50 Notable Nonfiction Books of the YearOne of Smithsonian Magazine's 10 Best Science Books of the Year One of Publishers Weekly's Best Nonfiction Books of the YearA New York Times Editor's Choice

The freshwater eel is a fish that makes two remarkable journeys, one at the beginning of its life, and another at the end. It is born in the ocean, lives its adult life in a freshwater stream, then returns to the ocean.

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.

In spring 1973, Michael Brown, a young freelance travel writer, took a phone call from a friend:'Why don't you come down to Somerset and see these things called elvers - they migrate up river at night on the high tides and the local's fish for them. It's called elvering.'And so began a lifetime's career, full of ups and downs, as a self- employed eel fisherman: from the enchantment of catching them by moonlight, to driving them in battered vans across Europe, to smoking mature eels, to selling them - Michael and his long-suffering wife Utta have never looked back. A heart-warming tale of running a small business on a shoe-string; and a passion for eels which never faded.

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.

Summary: This book gathers a collection of papers summarizing some of the latest developments in the thermomechanical processing of steels. The replacement of conventional rolling plus post-rolling heat treatments by integrated controlled forming and cooling strategies implies important reductions in energy consumption, increases in productivity and more compact facilities in the steel industry. The metallurgical challenges that this integration implies, though, are relevant and impressive developments that have been achieved over the last 40 years. The frequency of the development of new steel grades and processing technologies devoted to thermomechanically processed products is increasing, and their implementation is being expended to higher value added products and applications. In addition to the metallurgical peculiarities and relationships between chemical composition, process and final properties, the relevance impact of advanced characterization techniques and innovative modelling strategies provides new tools to achieve the further deployment of the TMCP technologies. The contents of the book cover low carbon microalloyed grades, ferritic stainless steels and Fe-Al-Cr alloys, medium-Mn steels, and medium carbon grades. Authors of the chapters of this "Thermomechanical Processing of Steels" book represent some of the most relevant research groups from both the steel industry and academia.

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.

The aim of the present work is to develop an in-depth understanding of the microstructural changes in neutron-irradiated beryllium. In particular, it aims to reveal the precise mechanisms leading to the observed tritium retention.Both, helium and tritium could be detected for the first time by high-resolution electron energy loss spectroscopy (EELS) within bubbles in the grain interior as well as along grain boundaries.
