Book Description
Freshwater eels are almost infinitely improbable creatures. They spawn and die in the middle of the ocean, often associated with undersea mountains. Their tra- parent, leaf-like larvae move with ocean currents for months or years until they approach the mouths of freshwater rivers. Then they undergo a dramatic transf- mation in morphology, physiology and behavior. They move from their planktonic oceanic environment, migrate upstream and live for several years as apex fre- water predators. Then, almost impossibly, as they become sexually mature, they reverse their migration downstream to the ocean and back to spawning grounds to complete their life cycle. The dramatic changes in their life cycles are incredible. The efforts to unravel the details of their life history have been truly daunting. Much of the past research was the work of dedicated individuals who devoted their lifetime research to these fishes. Freshwater eels merit a separate chapter in almost any textbook dealing with ichthyology, marine biology or animal migration. We know a great deal about some aspects of the biology of freshwater eels. However, our understanding of their bi- ogy still resembles a work of art as much as a work of science. To some it appears like the sweeping brush strokes of a Japanese Zen landscape, to others it resembles the work of a French impressionist, and to still others it appears as magic realism.

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
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.

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.

Book Description
Anguillid eels have fascinated biologists for centuries due to their spectacular long-distance migrations between freshwater habitats and their spawning areas far out in the ocean. This book provides a long overdue update on the biology and ecology of anguillid eels and features comprehensive coverage of the key features of the genus Anguilla. It c

Book Description
The book provides the most comprehensive review of lamprey biology since Hardisty and Potter’s five-volume “The Biology of Lampreys” published more than 30 years ago. Published in two volumes, it includes contributions from international lamprey experts, reviewing and providing new insights into the evolution, general biology, and management of lampreys worldwide. This first volume offers up-to-date chapters on the systematics, general biology, conservation status, and conservation needs of lampreys. It will serve as an important reference for researchers working on any aspect of lamprey biology and fishery managers whose mandate is to control or conserve lamprey populations.

Book Description
International Conference on Fish Migration and Bypass Channels held in Vienna in September 1996. It covers the range of fish pass technologies currently in use throughout the world and attempts to develop a wider, more ecological perspective on this formerly engineering-orientated discipline. Emphasis is placed on enhancing an understanding of fish migration behaviour, and achieving optimum design to meet the behavioural requirements of all known migratory species. Additional attention is paid to comparing the European trend towards constructing nature-like bypass channels with the highly technical solutions dominant in North America.
