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 Spawning Migration of the European Eel written by Guido van den Thillart and published by Springer Science & Business Media. This book was released on 2008-12-18 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

This book was released on 2019-10-31 with total page 551 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

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 Estimating Relative Abundance of Young-of-year American Eel, Anguilla Rostrata, in the Virginia Tributaries of Chesapeake Bay (spring 2018) written by Troy D. Tuckey and published by . This book was released on 2019 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: American Eel (Anguilla rostrata) is a valuable commercial species along the Atlantic coast of North America from New Brunswick to Florida. In the U.S., harvests have declined, with similar patterns occurring in the Canadian Maritime Provinces (Meister and Flagg 1997). An average of 62% of the annual landings of U.S. commercial harvest since 1993 have come from the Chesapeake Bay (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division, 9 February 2015). In 2013, Virginia commercial landings were approximately 100,298 lbs; since mandatory reporting began in 1993, average annual landings in Virginia have been 193,200 lbs or 19% of the U.S. American Eel harvest (personal communication from the National Marine Fisheries Service, Fisheries Statistics Division, 9 February 2015). A decline in abundance of American Eel has been observed in recent years with conflicting evidence regarding spatial synchrony throughout their range (Richkus and Whalen 1999; Sullivan et al. 2006). Hypotheses for the decline in abundance include shifts in location of the Gulf Stream, pollution, overfishing, parasites, altered oceanic conditions, and barriers to fish passage (Castonguay et al. 1994; Haro et al. 2000; Knights 2003). Additionally, factors such as unfavorable wind-driven currents may affect glass eel recruitment on the continental shelf and may have a greater impact than fishing mortality or continental climate change (Knights 2003). However, limited knowledge about fundamental biological characteristics of glass eels has complicated interpretation of juvenile abundance trends (Sullivan et al. 2006). The Atlantic States Marine Fisheries Commission (ASMFC) adopted the Interstate Fishery Management Plan (FMP) for the American Eel in November 1999. The FMP calls for efforts to collect American Eel data through both fishery-dependent and fishery-independent studies in coastal states. Consequently, member jurisdictions agreed to implement an annual survey for young-of-year (YOY or glass) American Eels. The survey is intended to “...characterize trends in annual recruitment of the YOY eels over time [to produce a] qualitative appraisal of the annual recruitment of American Eel to the U.S. Atlantic Coast” (ASMFC 2000). The development of these surveys began in 2000 with full implementation by 2001. Survey results provide necessary data on coastal recruitment success and further understanding of American Eel population dynamics. A recent American Eel benchmark stock assessment report found that the American Eel stock status is depleted and emphasized the importance of the coast-wide survey as an index of recruitment over the historical coastal range in the U.S. and an early warning of potential range contraction of the species (ASMFC 2012). In 2017, the Virginia Institute of Marine Science continued its spring sampling to estimate relative abundance of YOY American Eels in Virginia tributaries of Chesapeake Bay.
