Eels Biology Monitoring Management Culture And Exploitation Proceedings Of The First International Eel Science Symposium

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

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.

The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.

As the world's population continues to grow, so does the demand for seafood. Technological advances have enabled shrimp farming to change from traditional, small-scale businesses into a global industry. This has contributed to problems with serious disease outbreaks, which have already caused several regional wipe-outs of farm shrimp populations.The shrimp farming industry continues to grow and there is a need for a source of reliable and detailed information on shrimp farming, best practice and new developments, aimed at the shrimp industry, to facilitate future sustainable growth of the industry.While The Shrimp Book, published in 2010, was written from the academic perspective, The Shrimp Book II's focus is towards the industry perspective.

Countless millions of fish disappear into water abstractions used for power generation, water supply, irrigation and other uses. As fish stocks become depleted, increasingly, countries around the world see this as a threat to sustainability and are seeking to minimise these losses through legislation and introduction of best practice guidance on fish screening. In March 2011 the Institute of Fisheries Management, in the United Kingdom, organised a two-day conference which attracted international experts from the UK, Europe and the USA. Presenting key papers from the meeting this book will be of interest to academics, students, practitioners and environmental regulators everywhere.

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.
