Handbook of Fish Biology and Fisheries V 2 (Hardcover, Volume 2): Hart Handbook of Fish Biology and Fisheries V 2 (Hardcover, Volume 2)
Hart
R5,304 Discovery Miles 53 040 Ships in 12 - 19 working days

Recent decades have witnessed strong declines in fish stocks around the globe, amid growing concerns about the impact of fisheries on marine and freshwater biodiversity. Fisheries biologists and managers are therefore increasingly asking about aspects of ecology, behaviour, evolution and biodiversity that were traditionally studied by people working in very separate fields. This has highlighted the need to work more closely together, in order to help ensure future success both in management and conservation.


The "Handbook of Fish Biology and Fisheries" has been written by an international team of scientists and practitioners, to provide an overview of the biology of freshwater and marine fish species together with the science that supports fisheries management and conservation.


This volume, subtitled "Fisheries," focuses on a wide range of topics, including the history of fisheries science, methods of capture, marketing, economics, major models used in stock assessments and forecasting, ecosystem impacts, marine protected areas and conservation. It builds on material in Volume 1, "Fish Biology," which ranges from phylogenetics and biogeography to physiology, recruitment, life histories, genetics, foraging, reproductive behaviour and community ecology.


Together, these books present the state of the art in our understanding of fish biology and fisheries and will serve as valuable references for undergraduates and graduates looking for a comprehensive source on a wide variety of topics in fisheries science. They will also be useful to researchers who need up-to-date reviews of topics that impinge on their fields, and decision makers who need to appreciate the scientific background for management and conservation of aquatic ecosystems.

Red Snapper Biology in a Changing World (Hardcover): Stephen T. Szedlmayer, Stephen A. Bortone Red Snapper Biology in a Changing World (Hardcover)
Stephen T. Szedlmayer, Stephen A. Bortone
R5,536 Discovery Miles 55 360 Ships in 12 - 19 working days

Red Snapper Lutjanus campechanus, is an important commercial and recreational fish species and there has been much interest in maintaining its status among a variety of scientific, social and economic levels. Stocks are influenced by varying environmental conditions, changing fishing effort and efficiency, anthropogenic effects, inter- and intraspecific interactions, bycatch from other fisheries, and habitat alterations. Red Snapper Biology in a Changing World explores these changing factors and their potential effects on Red Snapper in the Eastern Atlantic region including the Gulf of Mexico and Southeastern U.S. The book will provide a better understanding of Red Snapper population fluctuations that will subsequently allow for better management decisions and more informed user groups in their efforts to maintain a sustainable fishery. It explores the responses Red Snapper have made, and are making, relative to their life history attributes such as early life history and adult ecology, especially attributes associated with population distribution and abundance, movement patterns, fish health issues and management success. A compendium of many papers presented at the 147th annual meeting of the American Fisheries Society in Tampa, Florida, this volume also includes additional research completed as a result of the symposium. It will be essential reading for fisheries scientists and managers, ichthyologists, resource and environmental managers, and policymakers who are involved with coastal fisheries.

Trout Culture - How Fly Fishing Forever Changed the Rocky Mountain West (Paperback): Jen Corrinne Brown Trout Culture - How Fly Fishing Forever Changed the Rocky Mountain West (Paperback)
Jen Corrinne Brown
R714 Discovery Miles 7 140 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

R5,864 Discovery Miles 58 640 Ships in 10 - 15 working days

Current growth in global aquaculture is paralleled by an equally significant increase in companies involved in aquafeed manufacture. Latest information has identified over 1,200 such companies, not including those organizations in production of a variety of other materials, i. e. , vitamins, minerals, and therapeutics, all used in varying degrees in proper feed formulation. Aquaculture industries raising particular economically valued species, i. e. , penaeid shrimps and salmonids, are making major demands on feed ingredients, while relatively new industries, such as til apia farming, portent a significant acceleration in demand for properly formulated aquafeeds by the end of the present decade and into the next century. As requirements for aquafeeds increases, shortages are anticipated in various ingredients, especially widely used proteinaceous resources such as fish meal. A variety of other proteinaceous commodities are being considered as partial or complete replacement for fish meal, especially use of plant protein sources such as soybean meal. In the past five years, vegetable protein meal production has increased 10% while fish meal production has dropped over 50%, since 1989, largely attributed to overfishing and serious decline in wild stock. Throughout fisheries processing industries, traditional concepts as "waste" have given way to more prudent approaches, emphasizing total by-product recovery. Feed costs are a major consideration in aquaculture where in some groups, i. e. , salmonids, high protein-containing feeds using quality fish meal, can account for as much as 40 to 60% of production costs.

The epic history of the "iron men in wooden boats" who built an industrial empire through the pursuit of whales. "To produce a mighty book, you must choose a mighty theme," Herman Melville proclaimed, and this absorbing history demonstrates that few things can capture the sheer danger and desperation of men on the deep sea as dramatically as whaling. Eric Jay Dolin begins his vivid narrative with Captain John Smith's botched whaling expedition to the New World in 1614. He then chronicles the rise of a burgeoning industry-from its brutal struggles during the Revolutionary period to its golden age in the mid-1800s when a fleet of more than 700 ships hunted the seas and American whale oil lit the world, to its decline as the twentieth century dawned. This sweeping social and economic history provides rich and often fantastic accounts of the men themselves, who mutinied, murdered, rioted, deserted, drank, scrimshawed, and recorded their experiences in journals and memoirs. Containing a wealth of naturalistic detail on whales, Leviathan is the most original and stirring history of American whaling in many decades.

R3,752 Discovery Miles 37 520 Ships in 12 - 19 working days

The book is a practical guide for the various steps in the post-harvest technology of frozen shrimps. Shrimps are one of the most common and popular types of seafood consumed globally. The book discusses some of the most sought-after shrimps such as Penaeus monodon, P. vannamei, and Macrobrachium rosenbergii. Good-quality shrimp is a prerequisite for the seafood business as it is used for human consumption. Lack of proper knowledge in raw materials handling and post-harvest processing is the main obstacle in quality shrimp production. Complex business policy, commitment break in both parties (buyers and sellers), competition with other seafood-producing countries, and fluctuation of currency in international seafood market are the factors affecting international seafood business. This book closes this gap in literature and facilitates the production of excellent-quality exportable frozen shrimp through informed practices from experts. The book includes information about packaging of frozen shrimp, inspection, and shipment. It also compiles different mathematical calculations which are in practiced in the processing industries. The book is essential reading for professionals in the shrimp producing and processing industries. It is also useful for researchers in fisheries science, aquaculture, food technology, and food microbiology.

At present, the supply of eggs and fry is one of the major constraints on future aquaculture development. For the majority of farmed species, production is totally dependent on harvesting of broodstocks or seed from wild populations At present we know little about the control of reproduction of most farmed finfish nor of the detailed nutrient, metabolic and husbandry requirements of the broodstock or the ways in which they might be managed to optimize seed production and improve the quality of eggs and larvae. Newer technologies such as ploidy and gender manipulation, induced spawning and cryopreservation are coming to the forefront of modern broodstock management and all of these topics are considered, in detail, in this new text. Broodstock Management and Egg and Larval Quality has been written as a standard text for commercial practitioners and students of aquaculture, fish biology and fisheries and provides a comprehensive review of current and future methods of broodstock and hatchery management. The range of marine and freshwater tropical and temperate finfish species considered, together with contributions from many of the worlda s most eminent fish biologists, provide comprehensive and international coverage of this increasingly important area of aquaculture.

Reviews: Methods and Technology in Fish Biology and Fisheries published by Kluwer Academic Publishers is a book series dedicated to the publication of information on advanced, forward-looking methodologies, technologies, or perspectives in fish and is especially dedicated to relevant topics addressing global, fisheries. This series international concern in fish and fisheries. Humans continue to challenge our environments with new technologies and technological applications. The dynamic creativity of our own species often tends to place the greatest burden on our supporting ecosystems. This is especially true for aquatic networks of creeks, lakes, rivers and ocean environments. We also frequently use our conceptual powers to balance conflicting requirements and demands on nature and continue to develop new approaches and tools to provide sustainable resources as well as conserve what we hold most dear on local and global scales. This book series will provide a window into the developing dynamic among humans, aquatic ecosystems (both freshwater and marine), and the organisms that inhabit aquatic environments. There are many reasons to doubt the increasing social and economic value technology has gained over the last two centuries. Science and technology represent stages in human development. I agree with Ernst Mayer when he said in Toward a New Philosophy of Biology (1988) that "endeavors to solve all scientific problems by pure logic and refined measurements are unproductive, if not totally irrelevant.

Hannesson
R3,908 Discovery Miles 39 080 Ships in 12 - 19 working days

Fisheries management must be based on biological expertise but must also, ultimately, satisfy economic criteria. Fisheries management which disregards economic objectives and needs might well succeed in preserving fish stocks but will waste other resources such as investment funds and labout and fail to serve the fishing industry effectively. This important new work is directed to fisheries management and is designed to help achieve an optimum balance between the biological and economic requirements of fisheries. An introduction to the economic analysis of fisheries compares optimal fishing to unregulated fishing. This is followed by a discussion of three popular fishing models and the problems arising from random fluctuations in fish stocks. The final chapter deals with the political economy of fishing regulations.

Karen A. Alexander
R4,469 Discovery Miles 44 690 Ships in 12 - 19 working days

This book explores the types of conflicts that occur over marine and coastal resources, the underlying causes, and attempts to prevent them. Despite the emergence of various marine and coastal governance approaches to address the effects of human activities within the marine environment, conflict continues. In this book, the author outlines the reasons conflicts can, and do, arise in the marine and coastal environment. Drawing on case studies from both the northern and southern hemispheres, the book takes a broad view of how we interact with our environment, of how and why conflict is perpetuated as a political and cultural phenomenon, and how this varies or remains constant across space and place. The case studies explore not only the underlying perceptions and needs of those involved in marine and coastal conflict and the types of conflicts that arise in oceanic and coastal areas, but also the underpinning reasons for these conflicts. Marine and coastal resource conflicts have the potential to derail conservation efforts and blue growth policies, as well as the United Nations Sustainable Development Goals. Thus, it is imperative we understand the drivers and exacerbating factors of marine and coastal conflict. Arguing that there is an urgent need for renewed thinking and focus on conflict prevention, the author develops a theory of marine and coastal conflict which allows us to understand those factors and the means to help prevent such conflicts arising in the first place. This book will be of interest to students and researchers of coastal and marine science and environmental management as well as those working in the field of marine resource management, including coastal zone managers and fisheries managers.

Food security and livelihoods in Africa face multiple challenges in the form of feeding a growing population on declining land areas under the impacts of climate change. The overall question is what kind of farming systems can provide resilient livelihoods? This volume presents a selection of existing farming systems that demonstrate how more efficient use of land and natural resources, labour and other inputs can have positive effects on household food security and livelihoods. It examines how aquaculture, integrated water management, peri-urban farming systems, climate-smart agriculture practices and parkland agroforestry contribute multiple benefits. Drawing on case studies from Kenya, Ethiopia, Nigeria and Burkina Faso, contributed by young African scientists, this book provides a unique perspective on multifunctional land use in Africa and illustrates how non-conventional uses can be profitable while promoting social and environmental sustainability. Tapping into the global discussion on land scarcity and linking food security to existing land use change processes, this volume will stimulate readers looking for diversified land uses that are compatible with both household and national food security ambitions. This book will be of great interest to students and scholars of African development, agriculture, food security, land use and environmental management, as well as sustainable development more generally, in addition to policymakers and practitioners working in these areas.

Judged by a dismaying track record and a consequent downturn in the reputation of fisheries scientists, fisheries management is certainly a candidate for calls for reinvention, with many of the world leaders in this area holding the view that no fishery has ever been properly understood or managed. With fisheries science in a state of flux, this extremely important book seeks a new paradigm that will place this flux of ideas in perspective and help us to choose those that will make fisheries management work. The book was planned at a symposium of over 100 fishery researchers at the Fisheries Centre, University of British Columbia, Vancouver, Canada and is organized into five parts: Why does Fisheries Science Need Reinventing?; New Policies; The Role of the Social Sciences; Ecology; Modelling. Carefully integrated and edited by three of the world's leading fishery scientists, this stimulating book should find a place on the shelves of all fishery scientists throughout the world. It will be an invaluable reference source to those studying fish biology, fisheries and oceanography and all those involved in fisheries policy decisions in government and university research establishments.
