"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.
"] just begin to find out that whaling will never do for me and have determined to leave the ship here if possible." That sentiment, expressed by a foremast hand aboard the ship Caroline in 1843, is one shared by many of the whalemen in this fascinating book. Interest in Herman Melville's Moby Dick has contributed to a substantial literature on the history and lore of the industry. But not until now has the vast body of surviving whaleship logs and journals been used to paint an encompassing picture of the difficult but colorful life aboard nineteenth-century American whaling vessels. Briton Cooper Busch, author of a definitive history of the American sealing industry, in this book only incidentally discusses the actual chase for whales. His focus instead is the life of whalemen at sea, and particularly the harsh discipline that kept men aboard through long and often dispiriting years. Busch depicts the complex social world aboard ship, defining and detailing such issues as crime and punishment, competing racial elements, the social distance between officers and men, sexual behavior, and the role of women aboard ships. For oppressed, discouraged, or simply bored whalemen, several escapes existed, from the rarest of all mutiny through labor protests of various types, to individual desertion or appeal to an American consul abroad. To each of these topics Busch devotes a chapter. He also provides glimpses of those occasional moments of relief such as a Fourth of July celebration and such somber moments as a death at sea. Fascinating details and original quotations from individual whalemen make this book more than a study of general trends. For anyone with even a casual interest in whaling, it is indispensable.
Understanding fish behavior in relation to capture processes in marine fisheries is of fundamental importance to reducing bycatch and discards, and to enhancing marine fisheries conservation efforts. A thorough understanding of this allows commercial fishers to more effectively capture target species while reducing the catch of unwanted species. "Behavior of Marine Fishes: Capture Processes and Conservation Challenges" provides the reader with principles, patterns, and characteristics on fish behavior and fish capture processes using several types of important commercial fishing gears. The book also highlights conservation challenges facing the marine capture fisheries in efforts to maintain sustainable use of marine resources and to reduce negative impacts to the marine ecosystem. This volume, with contributions from leading applied fish behaviorists and fishing gear technologists from around the world, will be a valuable reference for researchers, fishing gear technologists, fisheries managers, students, and conservationists.
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

The Story Of The Whaling Ships Up To The Present Day.
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.
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.

The format of Fish Hatchery Management is functional: hatchery requirements and operations; broodstock management and spawning; nutrition and feeding; fish health; fish transportation. We have tried to emphasize the principles of hatchery culture that are applicable to many species of fish, whether they are from warmwater, coolwater, or coldwater areas of the continent. Information about individual species is distributed through the text; with the aid of the Index, a hatchery manager can assemble detailed profiles of several species of particular interest. In the broad sense, fish culture as presented in Fish Hatchery Management encompasses not only the classical "hatchery" with troughs and raceways (intensive culture), but also pond culture (extensive culture), and cage and pen culture (which utilizes water areas previously considered inappropriate for rearing large numbers of fish in a captive environment). The coolwater species, such as northern pike, walleye, and the popular tiger muskie, traditionally were treated as warmwater species and were extensively reared in dirt ponds. These species now are being reared intensively with increasing success in facilities traditionally associated with salmonid (coldwater) species.
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.
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. It's the perfect book for anyone who loves fishing and the sea.
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.
This is the first collection of dramatic, first-person accounts of commercial fishing written by the men and women who work in the nation's most dangerous occupation. Nineteen diverse fisher-writers, from the famous to the unknown, take the reader swordfish harpooning on the Georges Banks, winter crabbing in the Bering Sea, sea-urchin diving off Maine, herring fishing in Alaska, shark-harpooning off Scotland and points between. Together, they plumb the extremes of living, working, and sometimes dying at sea, creating the most intensely personal portrait of fishing and fishermen to date.

"The Handbook of Freshwater Fishery Biology" summarizes the available data on age, growth, length weight, fecundity, reproductive behavior feeding habits, and necessary environment for each freshwater species. The comparison of species is presented in a manner easily used by fishery mangers and biologists.
Longlining is becoming increasingly more important as a method of fishing commercially for certain prime species of fish- particulary in the face of declining stocks. Longlining is much more selective that any other form of fishing and is thus more environmentally acceptable. Furthermore, longlining allows for the targeting of particular prime species and fish caught by this method are less damaged and thus hold a higher value. Despite the many major benefits of longlining, there are, as yet few books which address the technical and economic aspects of this method of commercial fishing. Written by an expert, this new book describes the principles and development of longlining fishing and explains the action of chemical sensing in fish and their behaviour towards baited hooks. Details of gear construction, the operation cycle for longlines, longline vessels and the different principles of mechanised baiting and on-board gear handling are provided and typical examples are given. The target species, gear parameters and catching efficiency, and the selective properties of longline gear are fully discussed whilst a concluding chapter compares longlining with other fishing methods.
Fisheries issues have been attracting increasing media attention in the wake of contamination scares, controversies over new government regulations, and environmental concerns about coastal zone management--especially the loss of wetlands, coastal erosion, pollution, and overfishing. Scrutinizing the people, policies, institutions, and issues tied to the shrimping industry in Mississippi, Paul Durrenberger provides this first examination ever of the complexities of an American fishing industry in a single geographical area. He presents an analysis of one elaborate system--from the toils and turmoils of the people who catch the shrimp to the quandaries facing the policymakers who try to regulate them. The shrimping industry, he contends, occurs on a series of interrelated levels and dimensions and is influenced by the ideas and actions of shrimpers, processors, fisheries managers, bureaucrats, creditors, environmentalists, and scientists. It is also one segment of a wider social, political, economic, and environmental totality. At a local level Durrenberger investigates the impact of competition from Vietnamese refugees, rivalry between bay and gulf fishermen, an escalating overpopulation of shrimpers in general, and wide-spread resistance to costly, federally mandated devices designed to save sea turtles. Exploring how the industry is increasingly bound to the global economy, he illuminates the threat to the livelihoods of independent shrimpers from ever increasing imports. Durrenberger assesses the adequacy of folk models of shrimpers and policymakers alike. Decisions about the industry's future, he argues, must be based on valid data and realistic expectations. Too often policies are derived from untested folk models--concepts formulated by participants to justify or rationalize rather than explain what they do. Based on detailed interviews, Gulf Coast Soundings will be a valuable resource for anthropologists, policymakers, public administrators, resource managers, sociologists, biologists, and anyone involved or interested in the economic and environmental future of the Gulf Coast, or more generally, in fisheries and coastal areas. |
