Biology and Management of the World Tarpon and Bonefish Fisheries (Paperback): Jerald S. Ault Biology and Management of the World Tarpon and Bonefish Fisheries (Paperback)
Jerald S. Ault
R2,069 Discovery Miles 20 690 Ships in 12 - 19 working days

The core of a multibillion dollar sport fishing industry, tarpon and bonefish, two of the earth's oldest creatures, are experiencing obvious and precipitous population decline. Experienced anglers in the Florida Keys suggest a drop of approximately 90-95 percent for the bonefish population over the last 65 years. Despite the economic value of the industry and scientific value of these ancient fish, very little information is available about their movements and migrations, population dynamics, life histories, and reproductive habits. With contributions from some of the world's leading experts, Biology and Management of the World Tarpon and Bonefish Fisheries synthesizes existing scientific literature, presents new perspectives, and introduces original scientific research to guide fishery management and conservation efforts for building sustainable fisheries. Divided into five sections, the book begins with an overview of the state of the world's fisheries for tarpon and bonefish. The second section reviews the biology and life history dynamics of these fish with contributions on conservation genetics, reproductive biology and early life development, as well as resolving gaps in evolutionary lineage and taxonomy. Covering population dynamics and resource ecology, the third section discusses migratory patterns and the use of tagging. Highlighting the lore and appeal of these fascinating sport fish, the book concludes by introducing a myriad of proposals designed to improve fishery sustainability by conducting census, enforcing catch-and-release programs, and supporting science-based management decision making. Promoting a better understanding of the biological and fishery management issues that are paramount to the sustainable future of these valuable fishery resources, Biology and Management of the World Tarpon and Bonefish Fisheries provides a foundation for discussion and broad communication about the past present and future of these magnificent fish.

Fish Pheromones and Related Cues (Hardcover): P W Sorensen Fish Pheromones and Related Cues (Hardcover)
P W Sorensen
R5,116 Discovery Miles 51 160 Ships in 12 - 19 working days

Pheromones are chemical cues that pass between members of the same species that convey specific, adaptive information. These cues, and related chemicals whose function are less well defined, are especially important to fishes because of their aquatic environments and complex behaviors. Pheromones are also of increasing interest in both basic and applied aspects of fish biology because they can be used to manipulate fish behavior and may explain phenomena such as fishery collapse. Fish Pheromones and Related Cues provides a timely synthesis of this growing body of research in freshwater and marine species and explores everything from how these chemical signals evolved, are produced, released and then processed, and finally to potential applications in fish culture and conservation. Fish Pheromones and Related Cues opens with a useful overview on the theory of chemical communication and definitions. Chapters then progress by examining the biological importance of pheromones in inter- and intra-species communication, the role these chemical cues play in a variety biological functions from reproduction to predation, and then how they evolved and are detected and recognized by fish nervous systems. Final chapters provide valuable insight into how pheromones can be measured, how pheromonal disruption can explain effects of environmental pollution, and lastly how they pheromones are being applied in real-world efforts to culture fish species and to conserve our wild populations and control invasive species. With far-reaching economic, evolutionary and ecological implications, Fish Pheromones and Related Cues will be an essential volume for anyone working in the fields of chemical communication, fish biology, fisheries science, aquatic conservation, ecology, invasive species control, and aquaculture

Trout Culture - How Fly Fishing Forever Changed the Rocky Mountain West (Hardcover): Jen Corrinne Brown Trout Culture - How Fly Fishing Forever Changed the Rocky Mountain West (Hardcover)
Jen Corrinne Brown
R2,420 Discovery Miles 24 200 Ships in 12 - 19 working days

From beer labels to literary classics like A River Runs Through It, trout fishing is a beloved feature of the iconography of the American West. But as Jen Brown demonstrates in Trout Culture: How Fly Fishing Forever Changed the Rocky Mountain West, the popular conception of Rocky Mountain trout fishing as a quintessential experience of communion with nature belies the sport's long history of environmental manipulation, engineering, and, ultimately, transformation. A fly-fishing enthusiast herself, Brown places the rise of recreational trout fishing in a local and global context. Globally, she shows how the European sport of fly-fishing came to be a defining, tourist-attracting feature of the expanding 19th-century American West. Locally, she traces the way that the burgeoning fly-fishing tourist industry shaped the environmental, economic, and social development of the Western United States: introducing and stocking favored fish species, eradicating the less favored native "trash fish," changing the courses of waterways, and leading to conflicts with Native Americans' fishing and territorial rights. Through this analysis, Brown demonstrates that the majestic trout streams often considered a timeless feature of the American West are in fact the product of countless human interventions adding up to a profound manipulation of the Rocky Mountain environment. https://www.youtube.com/watch?v=ZKMwEkKj9jg

It is a tribute to the vigour of research and development in aquaculture that we are able, in a relatively short time, to provide readers with a second volume in this series, which has such a diversity of high calibre research and developments to report. That the first volume was so well received has been a source of great satisfaction to the editors and supported their conviction as to the need for links to join the research laboratory to the fish farm by making current research available to a wider range of potential users. In this volume. we have changed the balance somewhat towards more specialised subject areas. We make no apology for this. as the modern aquaculture professional is concerned with a wide range of specialisms within the broader content of management and production, and there is every need to present such work in an acceptable format. Furthermore many of these specialised topics have a significance right across the range of production, are often economically criticaL and are therefore of con siderable and widespread importance. The first contribution. by Dr Derek Robertson, manager of the Institute of Aquaculture's Howietoun Fish Farm, covers just such a subject."

R5,611 Discovery Miles 56 110 Ships in 10 - 15 working days

Oryzias latipes, known as medaka, is a model organism from East Asia. Breeding of this small, egg-laying freshwater teleost fish has long been popular among hobbyists in Japan. Now, as biological science has entered the genome era, the medaka provides significant advantages that make it one of the most valuable vertebrate models: a large collection of spontaneous mutants collected over a century, the presence of highly polymorphic inbred lines established over decades, and a recently completed genome sequence. This book is the first comprehensive monograph to cover a variety of medaka research. It opens with a historical view of medaka, followed by a series of research topics in the four major areas where the medaka is increasingly important: genomics, genetics, and resources; organogenesis and disease models; germ cells, sex determination, and reproduction; and evolution. Readers will find state-of-the-art information on medaka genetics and genomics such as the first isolation of active transposons in vertebrates, the influence of chromatin structure on sequence variation, fine QTL analysis, and versatile mutants as human disease models.

This Technical Report presents the outcome of a Working Group that was established to determine broadly applicable sound exposure guidelines for fishes and sea turtles. After consideration of the diversity of fish and sea turtles, guidelines were developed for broad groups of animals, defined by the way they detect sound. Different sound sources were considered in terms of their acoustic characteristics and appropriate metrics defined for measurement of the received levels. The resultant sound exposure guidelines are presented in a set of tables. In some cases numerical guidelines are provided, expressed in appropriate metrics. When there were insufficient data to support numerical values, the "relative "likelihood of effects occurring was evaluated, although the "actual" likelihood of effects depends on the received level. These sound exposure guidelines, which are based on the best scientific information at the time of writing, should be treated as interim. The expectation is that with more research the guidelines can be refined and more cells in the tables completed. Recommendations are put forward defining the research requirements of highest priority for extending these interim exposure guidelines.

The Behaviour of Teleost Fishes (Paperback, Softcover reprint of the original 1st ed. 1986): Tony J. Pitcher The Behaviour of Teleost Fishes (Paperback, Softcover reprint of the original 1st ed. 1986)
Tony J. Pitcher
R1,602 Discovery Miles 16 020 Ships in 10 - 15 working days

This book is about the behaviour of teleosts, a well-defined, highly successful, taxonomic group of vertebrate animals sharing a common body plan and forming the vast majority of living bony fishes. There are weH over 22000 living species of teleosts, including nearly all those of importance in com mercial fisheries and aquaculture. Teleosts are represented injust about every conceivable aquatic environment from temporary desert pools to the deep ocean, from soda lakes to sub-zero Antarctic waters. Behaviour is the primary interface between these effective survival machines and their environment: behavioural plasticity is one of the keys to their success. The study of animal behaviour has undergone revolutionary changes in the past decade under the dual impact of behavioural ecology and sociobiology. The modern body of theory provides quantitatively testable and experi mentaHy accessible hypotheses. Much current work in animal behaviour has concentrated on birds and mammals, animals with ostensibly more complex structure, physiology and behavioural capacity, but there is a growing body of information about the behaviour of fishes. There is now increasing awareness that the same ecological and evolutionary rules govern teleost fish, and that their behaviour is not just a simplified version of that seen in birds and mammals. The details of fish behaviour intimately reflect unique and efficient adaptations to their three-dimensional aquatic environment.

As the aquaculture industry has expanded throughout the world, it has embraced the experiences of many fields of study to meet increasing technological challenges. The complexities of modern hatchery methodology, more intensive growout systems, and the application of diverse biological and physical sciences to aquatic animal husbandry have reached beyona the ability of most aquaculturists to enjoy an in-depth knowledge of all phases of the aquaculture process. More importantly, in order for tne culturist to have at hand the information necessary to make basic decisions, it requires an extensive library of textbooks and scientific literature. The Aquaculture Desk Reference serves as a concise compila tion of tables, graphs, conversions, formulas and design specifica tions useful to the aquaculture industry. It also provides examples, in a straightforward manner, of how information in tabulature can be used to derive values for specific system design and process strategies. Tables and graphs in this volume also provide back ground documentation and authority for further reference. The Aquaculture Desk Reference is a convenient source book that will alleviate the need for an extensive personal library to access basic information useful for practicing aquaculturists. Many thanks to Mrs. Ruth Aldrich for her assistance in the preparation of this book. My family, friends and associates also deserve my special appreciation for their encouragement and sup port.

R1,490 Discovery Miles 14 900 Ships in 10 - 15 working days

Although some nations, such as Japan, have invested in aquaculture research and developed major aquaculture industries, the opportunities for similar devel opment in the United States remain largely unnoticed. In a typical recent year the United States, which claims 20% of the world's marine fisheries resources, imported seafood worth $4. 8 billion and exported $l. 3 billion. In addition to the $3. 5 billion deficit in food-fish, was another $2. 7 billion deficit for nonedible fishery products. Next to oil, fishery products constituted the second highest drain on the United States balance of payments and accounts for a significant portion of the foreign trade deficit. Furthermore, fish consumption has been increasing in North America. In response to the demand for fishery products, aquaculture managers not only have the opportunity to realize economic profit, but in doing so can make an important contribution to reducing the national debt, providing employment, and enhancing our diet. This book might be considered a farm management text for those in aquaculture. It is intended to provide an introduction to aquaculture principles and an introduction to management, including business and people management, microeconomics, and the concepts of efficiency and productivity. I hope it will bridge the gap between conservationists, the academic community, and commer cial culturists. Abundant references should enable the reader to quickly access literature on most topics germane to the management of culture systems."

R1,566 Discovery Miles 15 660 Ships in 10 - 15 working days

Although catfish have been farmed for about 30 years and catfish farm ing is the most successful aquacultural enterprise in the United States, there are those who contend that catfish farming is still as much of an "art" as it is a science. This position is difficult to refute completely, particularly considering that some practices used in catfish farming ap pear to have little scientific basis. Skill coupled with a small dose of mysticism certainly playa role in the culture of catfish, and the catfish producer is faced with the unenviable task of rearing an animal in an environment that requires considerable management. Certain aspects may still be an "art" because research and technical information needed to support the industry have lagged behind industry growth; however, the basic principles underlying catfish farming are based on sound scientific evidence whose foundation was laid in the 1950s by work conducted at state and federal fish hatcheries in the southeastern and midwestern United States. Since that time, several university and government laboratories have expanded the scientific base for catfish farming. As a result, considerable information is available, but it is gen erally fragmented and exists in a multitude of diverse scientific and trade journals. The material is often too technical or abstract to be com prehensible to fish culturists and personnel in allied industries. This book fits the definition of the term handbook in the sense that it is intended as a book of instruction or guidance as well as a reference.

This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environ mental management. Each volume is a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement man's stewardship of our environment and the world's renewable re sources. For we must strive to understand the relationship between man and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other individual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to man, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem."

The Chapman and Hall Fish and Fisheries Series occasionally includes books devoted to a single taxon of fish that are of particular interest to fish and fisheries science. All three previous books of this type (Cichlid Fishes, Cyprinid Fishes, Sea Bass) have included important material on commercial fishery exploitation, but Hake: Biology, fisheries and markets, number 15 in the Series, is the first book that focuses on a major global fishery resource. This book brings together detailed analyses of the ocean habitats, biology, ecology, assessment and management of all the hake fisheries of the world for the first time. Globally, there are ten major world fisheries for 12 species of hake on both sides of the North and the South Atlantic, the Mediterra nean, the eastern North and South Pacific and New Zealand. The book includes an overview of industrial markets and products of hake. Hake fisheries are of particular economic interest as their location spans almost a complete spectrum of industrial development from major industrial countries like USA, Canada, Spain and Italy through New Zealand, South Africa, Argentina and Chile to Morocco, Peru, Mauritania, Namibia and Angola."

Fishery products are the world's most important source of animal protein, especially for the poor. Meeting the basic human needs for protein foods in the future will be a difficult challenge, especially as demand for fish has doubled since the 1950s. Realistically we can not expect to catch more food from the sea, so we must now turn to farming the waters, not just hunting them. The new challenge for planners is to accelerate aquaculture development and to plan for new production. As millions of people are moving from rural, inland areas to coastal cities we need to make urban areas not only centers of marketing and distribution, but also of production, particularly using recycled urban wastewater. This book on urban aquaculture includes papers from authors in the USA, Europe and Asia that review these emerging issues from the perspective of both developed and developing countries.

R2,083 Discovery Miles 20 830 Ships in 12 - 19 working days

Acknowledging the present inability to determine objectively the status and trends among estuarine ecosystems, the environmental research community has recently stepped up efforts to develop and evaluate meaningful estuarine indicators. This goal requires the effort of researchers from a broad spectrum of disciplines. In order to expedite this initiative, many of the world's leading estuarine scientists came together to present their views at the 2003 Estuarine Indicators Workshop. Derived from this conference of leading estuarine scientists, Estuarine Indicators presents the principles, concepts, practical use, and application of indicators in estuarine research and management practices. Topics include: the theory behind environmental indicators and their presumed attributes; the methods and protocols of indicator development and evaluation; a presentation of effective and ineffective indicator examples; and discussions of the future directions in research and management practices. This is an ideal reference for researchers, scientists, and students from any field dealing with estuaries and estuarine ecosystems. Its introductory-level chapters are accessible to novices and seasoned experts alike, and the applications and interpretation of research data suit the needs of environmental managers. This is a truly multidisciplinary, comprehensive compendium upon which future research will undoubtedly be built.

Konrad Dabrowski
R2,046 Discovery Miles 20 460 Ships in 12 - 19 working days

We are just beginning to discover the importance of vitamin C in the health of natural and man-made ecosystems. Synthesis of ascorbic acid is well understood, but algae as the only source of ascorbate in the aquatic food pyramid has not been explored. There is an expanding field of the culture of aquatic organisms that demand formulated feeds to best meet their requirements for health, growth, and reproduction. With over 100 species now cultured for human consumption, the question arises as to whether we have reliable information for the dietary needs for vitamin C for even a small percentage of these organisms. A comprehensive approach to the role of vitamin C at the cellular level as well as in the aquatic food chains, this book discusses growth and reproduction, disease resistance, and toxicology of aquatic organisms. Ascorbic Acid in Aquatic Organisms was written as the offshoot of a special session on aquatic organisms and practical aquaculture at the 1998 World Aquaculture Society (WAS) meeting. This book reviews the research already available and identifies new directions for research. It is a unique combination of good nutrition research, ecology, and practical aquaculture (for instance brine shrimp enrichment). This interdisciplinary volume will appeal to marine fish culturists, aquatic biologists, comparative and evolutionary cellular physiologists, and environmental toxicologists.

R2,048 Discovery Miles 20 480 Ships in 12 - 19 working days

Interrelationships Between Corals and Fisheries is derived from a workshop held by the Gulf of Mexico Fishery Management Council in Tampa, Florida in May 2013, where world authorities came together to discuss the current problems in managing tropical fisheries and offered suggestions for future directions for both researchers and environmental resource managers. This book addresses current and emerging threats as well as challenges and opportunities for managing corals and associated fisheries. It provides an information baseline toward a better understanding of how corals and the consequences of coral condition influence fish populations, especially as they relate to management of those populations. The book contains content from presentations modified as a result of interactions and discussions with colleagues and peer reviews by global experts in corals and fisheries. Many chapters include additional materials not presented in the workshop. There are also papers that were not presented at the workshop but contribute to the central theme of the book. Topics covered include: Global decline in coral reefs and impacts on fishery yields Distribution and diversity in the Gulf of Mexico Implementation of Coral Habitat Areas of Particular Concern (CHAPCs) Deepwater coral/sponge habitats Coral populations on offshore platforms Mangrove connectivity for sustaining coral reef fisheries Restoring deepwater coral ecosystems and fisheries after the Deepwater Horizon oil spill Predictive mapping of coral reef fish Covering a range of subject matter, most of the chapters offer suggestions for future research on the interrelationships between corals and fisheries. In addition, the final chapter presents a summary on these interrelationships and discusses managing them for the future.

Global climate change affects productivity and species composition of freshwater and marine aquatic ecosystems by raising temperatures, ocean acidification, excessive solar UV and visible radiation. Effects on bacterioplankton and viruses, phytoplankton and macroalgae have farreaching consequences for primary consumers such as zooplankton, invertebrates and vertebrates, as well as on human consumption of fish, crustaceans and mollusks. It has affected the habitation of the Arctic and Antarctic oceans the most so far. Increasing pollution from terrestrial runoff, industrial, municipal and household wastes as well as marine transportation and plastic debris also affect aquatic ecosystems.
