Common carp are hugely popular in aquaculture, course angling, commercial fisheries and as an ornamental fish. While their native range extends from the lakes and rivers of Japan to the Danube Basin in Eastern Europe, their usefulness has led to them being introduced to many waterways outside their native range. In this book, the authors present topical research in the study of the habitat, management and diseases of carp. Included in this compilation are the strategic management of the photoperiodic schedule and melatonin profile in the regulation of carp reproduction; invasive parasites of common carp in Europe; impacts of the common carp on freshwater ecosystems and the utilisation of carbon, nitrogen and phosphorus in carp culture ponds..
This book examines the management, disease control and environment of fish farms. Topics discussed include the environmental considerations of antibiotics and antifoulants in salmonid aquaculture; fish farming technology in the Morogoro Region of Tanzania and Tunisia and off-shore demersal trap fishery in the southern Arabian Gulf.
The Story Of The Whaling Ships Up To The Present Day.
In "Shell Games," journalist Craig Welch delves into our nation's waters and wildlands in search of America's most unusual criminals. The resulting detective story is filled with butterfly thieves, bear poachers, shark-trafficking pastors--and a rogues' gallery of double-crossing crooks who get rich smuggling bizarre marine creatures. Puget Sound is home to the geoduck (pronounced "gooey duck"), the world's largest burrowing clam--a seafood delicacy worth millions on the international black market. Outlaw scuba divers pursue this prize while dodging cops, committing arson, and hiring hit men to eliminate their rivals. Detective Ed Volz has spent decades chasing fish and wildlife smugglers. Now, he and a team of federal agents are desperate to take down the most remarkable thief they've ever hunted: a darkly charming con man who works both sides of the law and calls himself the "Geoduck Gotti."
Terranova is the story of Spain's twentieth-century industrial cod fishery on the Grand Banks of Newfoundland. It combines oral history (including interviews with over 300 participants in the fishery) with socio-political-economic history to describe how the industry and Spain itself evolved over seven decades. Terranova pays special attention to how work and life onboard trawlers changed in 1926, when Spain's industrial fishery began, and how they have evolved through the turn of the twenty-first century. It concludes by describing how technological advances and increased competition among fishers brought the collapse of the Newfoundland cod fishery in 1992.
This book reviews the fisheries of New England - "the poster child of mismanagement" - since 1977. It finds that many of the explanations offered for the New England problems are incorrect or irrelevant or counterproductive. It suggests that the problems lie in two general categories: first, the legislative and administrative context of management; and second and more serious, fundamental issues concerning fishing technologies, and lack of effective effort control strategies and an operational hypothesis of the dynamics of marine ecosystems. These latter issues are not confined to New England, but are inherent in most marine fisheries wherever they may be found. The book suggests a new concept for benign and selective fishing technologies, and it recommends a thorough review and analysis of the efficacy of effort control concepts. It proposes a management strategy based upon the hierarchical concept of ecosystems that could eliminate many of the current problems of management.
"Aquaculture Economics and Financing: Management and Analysis" provides a detailed and specific set of guidelines for using economic and financial analysis in aquaculture production. By discussing key issues such as how to finance and plan new aquaculture business, how to monitor and evaluate economic performance, and how to manage capital, labor, and business risk, the book equips aquaculture professionals, researchers, and students with important information applicable to a wide range of business decisions. Chapters address each stage of developing an aquaculture business, including financing, marketing, and developing a business plan to managing cash flows and analyzing financial statements. Each chapter includes a detailed example of practical application taken from every-day experience. Written in straightforward terminology facilitating ready application," Aquaculture Economics and Financing: Management and Analysis" is an essential tool for analyzing and improving financial performance of aquaculture operations.
Since the early 1800s, people have made a living fishing and harvesting mussels in the lower Ohio Valley. These river folk are conscious of an occupational and social identity separate from those who earn their living from the land. Sustained by a shared love of the river, deriving joy from the beauty of their chosen environment, and feeling great pride in their ability to subsist on its wild resources and to master the skills required to make a living from it, many still identify with the nomadic houseboat-dwelling subculture that flourished on the river from the early nineteenth century to the 1950s. Today's community of fisherfolk is small and economically marginal, but their activities sustain a complex set of traditional skills and a body of verbal folklore associated with river life. In Flatheads and Spoonies, Jens Lund describes the activities, boats, gear, verbal lore, and sense of identity of the fisher folk of the lower Ohio River Valley and provides historical and ethnobiological background for their way of life. Lund connects the importance of river fish in the diet of inhabitants of the valley to local fishing activities and explores the relationship between river people and those whose culture is primarily land-based, painting a colorful portrait of river fishing and river life. This book offers a look -- historical and ethnographic -- at a little-known aspect of traditional life in the American Midwest, still surviving today despite immense changes in environment, resources, and economic base.
Since the first publication of Population Genetics and Fishery Management in 1987, significant technological, analytical and conceptual changes have occurred in the topic area of this book, and it is now long out of print but a demand for this book has persisted, as reflected by its translation into Russian in 1991, and the high current price of the occasional copy that becomes available on the used book market. Colleagues who have encouraged this reprinting have said that by explaining basic population genetics in a fisheries context, the book continues to serve as an excellent starting point for approaching complex recent developments. This book grew out of a series of lectures by Dr. Nils Ryman (Stockholm University) on genetics and fisheries management. Together with Dr. Fred Utter (U.S. National Marine Fisheries Services), they have edited contributions from 24 authors from four continents. The editors deliberately chose contributing authors who are primarily geneticists rather than fisheries managers with the intention of encouraging the application of the principles of population genetics to fisheries management. "Although most of the information collected in this book is available in other places, nowhere else has it been directed specifically to fisheries and related problems. One of its strengths lies in the fact that the chapters are written by first-class researchers in the topics discussed. This ensures that the material is up to date, and it also makes the book very useful to other researchers. I strongly recommend it to all students, scientists and managers of fisheries." New Zealand Journal of Marine and Freshwater Research, 1987
Aquaculture is a rapidly growing, successful approach to improving diets by providing more high quality fish and shellfish protein. It is also an industry with major unresolved issues because of its negative impact on the environment. This book is a pioneering effort in the development of environmentally benign aquaculture methods.
"A marvelous, compelling tale"("Rocky Mountain News") from the "New
York Times" bestselling author of "Salt" and "Cod."
This book presents the latest research on aquaculture which is the cultivation of aquatic organisms. Unlike fishing, aquaculture, also known as aquafarming, implies the cultivation of aquatic populations under controlled conditions. Mariculture refers to aquaculture practised in marine environments. Particular kinds of aquaculture include algaculture (the production of kelp/seaweed and other algae); fish farming; shrimp farming, shellfish farming, and the growing of cultured pearls.
The Story Of The Whaling Ships Up To The Present Day.
During the first half of the 1990s, in response to the increasing concern about many of the world's fisheries, a number of international fisheries instruments provided an impetus for countries to strengthen their fisheries management. A key step in supporting such efforts is the development of more detailed, systematic and comparable information on fisheries environments and management trends. The State of World Marine Capture Fisheries Management Questionnaire was developed by FAO in 2004 to help meet this need. The results have been grouped by region and are reported in this publication. More than a decade later, we are able to look back to see how countries responded, to examine whether more fisheries are managed and to determine whether the management tools and strategies employed have improved the overall situation in marine capture fisheries. Trends in legal and administrative frameworks, management regimes and status of marine capture fisheries are analysed for 29 countries in the Pacific Ocean and presented in this report and on the accompanying CD-ROM as an easy-to-read and informative reference for policy decision-makers, fishery managers and stakeholders.

The past decade has witnessed an extremely rapid development in the "science" of mariculture, especially the design and operation of modern oyster seed hatcheries. The Department of Marine Culture at the Virginia Institute of Marine Science over the past seven years has developed an oyster hatchery system through research and cooperative efforts with the fisheries industry. This system, including the biological protocol to be described in detail on the following pages, has been tested successfully and is a modification of that system used at Chesapeake Sea Farms, Inc. in Ridge, Maryland. It is important to stress this system represents a totally integrated concept-an interdependent system, which, if taken apart and used as separate steps, will yield poor results, especially when modifying the oyster larval food diet. The detailed instructions are not meant to bore the expert, but are included to make sure the results can be reproduced.
Although this book provides information on warmwater aquaculture in the United States that should be useful to aquacultural suppliers, lending institutions, resource managers, interested citizens, and others, the principal purpose is to tell the fish farmer what is to be done, why it is to be done, and how to do it. The reader is provided with the essentials of successful warmwater fish farming. The emphasis in this book is clearly on channel catfish, ranging from maintenance of brood stock to the culture of fingerlings and the production of market-sized fish. However, production techniques are described for numerous other fishes of commercial importance, as well as for crayfish, prawns, bullfrogs, and alligators. Other topics of potential interest to practicing aquaculturists include polyculture; nutrition and feeding; harvesting, holding, and transporting of fish; parasites and diseases; and multiple use of land and water.
Systems Analysis and Simulation in Wildlife and Fisheries Sciences William E. Grant This hands-on approach provides guidance to the step-by-step applications of systems analysis and simulation to questions about ecological systems. At the same time, it explains general principles without requiring that readers have a strong background in mathematics, statistics, or computer science. Chapter 1 traces the development of systems ecology introducing basic concepts, while Chapters 2 through 5 present the four phases of systems analysis: conceptual model formulation, quantitative specification of the model, model validation, and model use. 1986 (0 471-89236-X) 338 pp. Bioeconomic Modelling and Fisheries Management Colin W. Clark Discusses the management of commercial marine fisheries and the relationship between the economic forces affecting the fishing industry and the biological factors that determine the production and supply of fish in the sea. Topics focus on methods of preventing overfishing and overcapitalization, economically effective and practical forms of regulation, management of developing fisheries, natural fluctuations of fish stocks, and complexities of marine ecosystems. 1985 (0 471-87394-2) 291 pp. Methods in Marine Zooplankton Ecology Makoto Omori and Tsutomu Ikeda Encompassing basic principles, procedures, and research problems, this book serves as a complete guide to current methods used in the study of marine zooplankton. The techniques are equally applicable to small organisms and to the larval stages of larger, commercially important organisms. Chapters start with a brief, but well-summarized introduction to zooplankton, followed by field sampling strategies andlaboratory methods, and then conclude with estimates of productivity and analysis of community structure. Each method is described in detail, including a discussion of the problems inherent in using it. 1984 (0 471-80107-0) 322 pp.
This is a reprint of the classic first published in 1957. One of the authors, Raymond Beverton, recently died. His co-author, Sidney Holt, has written a new Foreword to this printing in which he reviews events in fisheries research and management through the past 50 years as these relate to their joint work. On the Dynamics of Exploited Fish Populations has become the most widely cited fisheries book ever published and the fact that the bulk of the information contained within its covers is still valid has led to this reprinting. Beverton and Holt's great work created a solid foundation for one of the two major global visions of the science of fisheries. This book was the genesis of the modern age-structured approach to the optimal management of fishery resources. Their approach led directly to a formulation of the fishery catch equation with almost universal applicability. Its advantage was that it produced easily interpreted outputs that could be clearly and directly applied to any fishery. Ultimately, this approach was the forerunner to VPA and allied techniques, the core of modern catch forecasting used in setting quotas and in managing commercial fisheries worldwide. Although the perception of the objectives of fisheries research has changed since the 1950s, and computers now enable calculations, data analysis, and theoretical exploration far beyond their capability at the time, Beverton and Holt will continue to be a source of inspiration and insight for many years to come. Sidney J. Holt was educated at Reading University, England. He has held academic positions at St John's College, Cambridge, England; University of California at Santa Cruz; University of Rhode Island; University of Malta. He is the author of 400 scientific papers, book chapters and popular articles, especially in the fields of fisheries science and management, conservation, protection of marine mammals, especially whales. He served 25 years in the United Nations system of Specialised Agencies (including the FAO in Rome, UNESCO as Secretary of the Intergovernmental Oceanographic Commission and Director of Division of Marine Science; Marine Mammals; Advisor to the United Nations Environment Programme; UN Adviser on Mediterranean Marine Affairs, in which capacity he founded and served as first Director of, the International Ocean Institute, in Malta). Since his formal retirement Dr Holt has served on the delegations of Italy and of the Republic of Seychelles to the International Whaling Commission, and also as adviser to the delegations of France and Chile. Dr Holt has worked extensively with several Non-Governmental Organisations concerned with marine conservation. Apart from continuing to write and campaign Dr Holt advises the Third Millennium Foundation, and serves as Executive Director of the International League for the Protection of Cetaceans, which he founded 18 years ago.
Originally published by the Bureau of Fisheries of the U. S. Department of Commerce in 1922, this may be the only book ever published on the operation of commercial aquariums. At the time of original publication the author, Charles Haskins Townsend was Director of the New York Aquarium.The writer has had long experience in the management of the aquarium in New York City and has assisted in planning certain aquariums already built as well as others projected. He was connected with the National Commission of Fisheries during the period when that organization maintained temporary aquariums at the great industrial exhibitions held in this country and observed some of them in operation. Millions of people saw those aquariums of the past, while other millions enjoy the few that exist here at present.Having supplied information recently to a score of cities that contemplate constructing aquariums, the writer has felt it incumbent upon him to set forth the essentials of the matter for the guidance of an increasing number of inquirers. The present discussion is based largely on the methods of the large aquarium in New York City, which has been in operation for 30 years and is now undergoing extensive modernization.
Just before Christmas, Linda meets up with her best friend and fellow fisherman Alden Leeman for lunch and a drink at the Dry Dock, a well-worn watering hole in Portland, Maine. Alden, the captain of Linda's first fishing expedition, has seen his share of mishaps and adventures at sea. When Linda shares memories of navigating her ship through one of the craziest storms she's ever seen, Alden quickly follows up with his own tales. Then other fishermen, who are sitting on the periphery attentively listening, decide to weigh in with yarns of their own.All Fishermen Are Liars brims with true stories of the most eccentric crew member, the funniest episode, the biggest fish, and the wildest night at sea. Denizens of the Dry Dock drift in and out as the bar begins to swell with rounds of drinks and tales that increase in drama. Here are some of the greatest fishing stories ever--all relayed by Linda Greenlaw in her inimitable style.All Fishermen Are Liars will give readers what they have come to love and expect from Linda Greenlaw--luminous descriptions and edge-of-the-seat thrills.
