Carp and Pond Fish Culture 2e (Hardcover, 2nd Edition): L. Horvath Carp and Pond Fish Culture 2e (Hardcover, 2nd Edition)
L. Horvath
R3,914 Discovery Miles 39 140 Ships in 10 - 15 working days

During the 10 years since publication of the first edition of this well-recieved book, the carp and pond fish farming industry has continued to grow steadily. Fully revised and updated, this comprehensive new edition provides a detailed and practical guide to the principles and practices of farming cyprinid fish, using traditional and modern pond culture techniques.

Although concentrating primarily on carp culture, this can be regarded as a model for the production of many species in ponds; the most widely used method of producing fish throughout the world. Specific information is also included for other species, such as Pike, Wels Catfish and Goldfish and now African Catfish and Sterlet. The authors, who between them have many years' experience farming fish as well as researching and teaching the subjects covered in the book, have produced a most useful and timely second edition.

The book will be of great interest to fish farmers, researchers, teachers and students in the area of aquaculture and related subjects, to all those involved specifically in the carp farming industry and in the aquaculture of other pond-cultured species. Copies of the book should be available as a reference source in libraries in academic and research establishments where aquaculture is studied an taught, and for practical reference on fish farms.

Migration of Freshwater Fishes (Hardcover): Lucas Migration of Freshwater Fishes (Hardcover)
Lucas
R6,095 Discovery Miles 60 950 Ships in 10 - 15 working days

Recent studies have increasingly demonstrated the widespread existence of spatio-temporal variations in the abundance and distribution of species of freshwater fishes, previously assumed not to move between habitats. These movements are often on a seasonal or ontogenetic basis, for spawning, feeding and refuge, and in many cases are fundamental for the successful completion of lifecycles.

This important book provides a single source for a range of previously widely dispersed information on these movements of fish in fresh waters, covering potamodromous fishes as well as the more familiar diadromous species, worldwide. Contents include full descriptions of types of migration and spatial behaviour, the stimulus and capacity for fish to migrate, the effects of climate on patterns of migratory behaviour, a taxonomic analysis (mostly by family) of freshwater fish migration, methods for studying migration, and details of the impacts of man's activities on freshwater fish migration.

"Migration of Freshwater Fishes" provides an excellent and comprehensive reference to which the river manager, biologist or student can now refer to obtain information, advice and current opinion on the migratory behaviour of most taxonomic groups of fishes occurring in fresh water. University libraries and aquatic research stations should also have copies of this essential reference book on their shelves.Well-known international authors.Of great commercial importance to fisheries and professional angling bodies.Draws together much new information in one place.Detailed review of world wide migratory behaviour for most groups of freshwater fishes.Pure and applied relevance, for academics, fisheries scientists, river managers and conservationists.This comprehensive book includes 67 tables and figures and over 1,400 references.

Scottish Arctic Whaling (Paperback): Chesley W. Sanger Scottish Arctic Whaling (Paperback)
Chesley W. Sanger
R625 Discovery Miles 6 250 Ships in 9 - 17 working days

Scottish Arctic Whaling brings to light a previously little-known but important Scottish industry. The author's extensive use of original sources such as log-books and diaries shows that hundreds of whaling vessels, sailing variously from sixteen east-coast Scottish ports, harvested more than 20,000 bowhead whales at East Greenland, Davis Strait and Baffin Bay during the eighteenth and nineteenth centuries. And they did so under almost unimaginably demanding and hazardous conditions. More than 110 ships were lost, while others were often detained within the pack-ice, causing the whale men to suffer starvation, disease, scurvy, frostbite and death. In 1836 alone, more than 100 whalers on the Advice and Thomas, Dundee, and Dee of Aberdeen perished when they became entrapped at Davis Strait. Nevertheless, by the second half of the nineteenth century, through hard work, skill and perseverance, Scotland had a virtual monopoly on Arctic oil and bone, until seriously depleted stocks and the outbreak of the First World War brought the industry to a close.

"Fishes and Forestry" "Worldwide Watershed Interactions and Management" Edited by T. G. Northcote and G. F. Hartman


Many species of fish occupying inland waters reside in watersheds that were or still are surrounded by forests and are dependent in major ways upon such cover. The interactions between fishes and forests are complex, multifaceted, dynamic processes involving most inland surface waters, forests, subsurface waters, geology and soils, climate and its changes, and the biotic components of the relevant ecosystems. These interactions also include the aspects of forestry tied to human development, economics, population growth and even philosophies.


"Fishes and Forestry" is truly a landmark publication. The editors, Professors Northcote and Hartman, have drawn together and carefully edited chapters written by 56 scientists from around the world, covering a vast wealth of information never before appearing within the covers of one book. Following an introductory chapter, this exceptional work is broadly divided into sections covering: the ecology of forests, streams, lakes and estuaries; fish biology and ecology; forestry activities and their effects on aquatic systems and fishes; 14 chapters covering examples of fish-forestry interactions from around the world and a final section covering means of effecting better fish-forestry interactions.

"Fishes and Forestry" is an essential purchase for all those involved in inland fisheries, forestry and their interaction, including fisheries scientists, fish biologists, ecologists, environmental scientists and forestry scientists. Libraries in all universities and research establishments where these subjectsare studied and taught should have several copies on their shelves.

Entangled Sensemaking at Sea - Bycatch Management That Makes Good Social and Ecological Sense (Paperback): Jason Good Entangled Sensemaking at Sea - Bycatch Management That Makes Good Social and Ecological Sense (Paperback)
Jason Good
R1,278 Discovery Miles 12 780 Ships in 10 - 15 working days

Sustainable commercial fishing, species conservation, and bycatch are contentious topics. Great emphasis has been placed on the sustainable sourcing of particular species that we buy at the store and order in restaurants, but how can we trust that the fish on our plates, from a system-wide perspective, have been appropriately sourced? Even in what are commonly considered to be the best-managed fisheries in the world (i.e., Alaskan fisheries), thousands of tons of fish are wasted each year in the interest of providing certain species in certain ways to certain people, at certain prices. Are the management practices and regulations that we think are helping actually having the desired outcomes in terms of the effective use of natural resources? This book presents a framework that can enhance our understanding, research, and regulation of frontline organizing processes in commercial fisheries, which may be generalized to other resource extraction industries. It enables readers to better grasp and respond to the need to develop practices and regulations that involve effective use of all natural resources, rather than just a chosen few. The book is especially important to researchers and practitioners active in the fishing industry, and natural resource managers and regulators interested in understanding and improving their management systems. It is also highly relevant to organization and management researchers interested in coupled human and natural systems, ecological sensemaking, the role of quantum mechanics in organizational phenomena, sociomateriality, and sustainability. The book uses the real-world case of an Alaskan fishing fleet to explore how the commercial fishing industry (which includes businesses, management agencies, regulatory bodies, and markets, among others) entangles itself with natural phenomena in order to extract resources from them. After gaining a better understanding of these processes can we see how they can be improved, especially through changes to regulatory management systems, in order to foster not only more sustainable, but also less wasteful (these two goals are not necessarily interdependent in today's regulatory management systems), natural resource extraction and use. Such an understanding requires exploring how regulations, natural phenomena, human sensemaking processes, and market forces entangle at sea to materialize the fish that make their way to our plates - as well as those that, importantly, do not.

Making Fishery Agreements Work - Post-Agreement Bargaining in the Barents Sea (Paperback): Geir Honneland Making Fishery Agreements Work - Post-Agreement Bargaining in the Barents Sea (Paperback)
Geir Honneland
R973 Discovery Miles 9 730 Ships in 10 - 15 working days

Why do people obey the law? And why do states abide by their international commitments? These are among the questions raised in this important book. The setting is the Barents Sea, home to some of the most productive fishing grounds on the planet, including the world's largest cod stock. Norway and Russia manage these fish resources together, in what appears to be a successful exception to the rule of failed fisheries management: stocks are in good shape, institutional cooperation is expanding and takes place in a constructive atmosphere. The author argues that post-agreement bargaining helps activate norms and establish standard operating procedure that furthers precautionary fisheries management. The Barents Sea fishery is seen as one of the best-managed international fisheries in the world, and the book specifically enquires into the lessons to be learned from the Norwegian-Russian partnership. It will therefore prove to be of invaluable interest to practitioners, scholars and policy makers working in the field of fisheries management and environmental agreements.

Globalization: Effects on Fisheries Resources (Paperback): William W Taylor, Michael G. Schechter, Lois G. Wolfson Globalization: Effects on Fisheries Resources (Paperback)
William W Taylor, Michael G. Schechter, Lois G. Wolfson
R1,893 Discovery Miles 18 930 Ships in 10 - 15 working days

Globalization is a multidimensional issue, and its impacts on world resources cross and integrate environmental, economic, political and cultural boundaries. Over the last few decades, the push towards globalization has brought a new dimension in which managers of fisheries and water resources will need to operate, both at the local and global level of governance. In order to effectively address the future sustainability of these resources, it is critical to understand the driving factors of globalization and their effect on fisheries ecosystems and the people who depend on these resources for their cultural and societal well-being. This 2007 book discusses the social and political changes affecting fisheries, the changes to ecological processes due to direct and indirect impacts of globalization, the changing nature of the goods and services that fisheries ecosystems are able to provide, and the resultant changes in markets and economic assessment of our fishery resources.

Catching Hell - The Insider Story of Seafood from Ocean to Plate (Hardcover): Allen Ricca, Joe Muto Catching Hell - The Insider Story of Seafood from Ocean to Plate (Hardcover)
Allen Ricca, Joe Muto
R606 R537 Discovery Miles 5 370 Save R69 (11%) Ships in 9 - 17 working days

In Catching Hell, longtime seafood mogul Allen Ricca and author Joe Muto take readers behind the scenes of the high-end restaurant world and the international market for seafood, and how that industry has been impacted perhaps like no other due to the COVID-19 pandemic. This book exposes the fact that the American diner is being lied to on a regular basis. The culprit varies - sometimes it's a chef or restaurant owner trying to cut corners to save money; other times it's an unscrupulous supplier looking to pass off poor product to an unwitting receiver. And the cost of that scam eventually gets passed on to the consumer, whether it be in the form of higher prices at restaurants and markets, lower quality (or even counterfeit) product getting delivered onto your plate, or - God forbid - food poisoning. Furthermore, Ricca argues, the pandemic has only increased corruption in this industry. This book serves as both an expose and a call to arms, empowering consumers with the knowledge to make more informed choices when dining out. Some of the things this explosive book reveals: The one fish you should never order, one that's always a rip-off. (And the one fish that's always a delicious, virtually-unknown bargain.) Why restaurants that advertise "fresh" fish are almost always lying. How to get your favorite restaurant to treat you like royalty - without dropping thousands of dollars. How the covid-19 pandemic has impacted our food supply chain and what it has meant for the everyday worker.

The 2020 edition of The State of World Fisheries and Aquaculture has a particular focus on sustainability. This reflects a number of specific considerations. First, 2020 marks the twenty-fifth anniversary of the Code of Conduct for Responsible Fisheries (the Code). Second, several Sustainable Development Goal indicators mature in 2020. Third, FAO hosted the International Symposium on Fisheries Sustainability in late 2019, and fourth, 2020 sees the finalization of specific FAO guidelines on sustainable aquaculture growth, and on social sustainability along value chains. While Part 1 retains the format of previous editions, the structure of the rest of the publication has been revised. Part 2 opens with a special section marking the twenty fifth anniversary of the Code. It also focuses on issues coming to the fore, in particular, those related to Sustainable Development Goal 14 and its indicators for which FAO is the "custodian" agency. In addition, Part 2 covers various aspects of fisheries and aquaculture sustainability. The topics discussed range widely, from data and information systems to ocean pollution, product legality, user rights and climate change adaptation. Part 3 now forms the final part of the publication, covering projections and emerging issues such as new technologies and aquaculture biosecurity. It concludes by outlining steps towards a new vision for capture fisheries. The State of World Fisheries and Aquaculture aims to provide objective, reliable and up-to-date information to a wide audience - policymakers, managers, scientists, stakeholders and indeed everyone interested in the fisheries and aquaculture sector.

R4,206 Discovery Miles 42 060 Ships in 10 - 15 working days

The species of hake, making up the genus Merluccius, are commercially important and currently largely over exploited, with many stocks badly depleted and showing only limited signs of recovery. From the end of the 1990s, concepts such as sustainability, ecosystem-based approaches to fisheries management, a code for the responsible conduct for fisheries, governance and others have emerged or have been considered by politicians, stakeholders and society. Moreover, new tools for stock assessment have been developed. But many hake stocks of the genus Merluccius show no sign of restoration. Hakes: Biology and Exploitation brings together a wealth of important information on the biology and exploitation of hake and hoki stocks around the world. Each chapter provides an overview of the fisheries of each species in an ecological and environmental context, looking at stock distribution, characteristics of the environment, life history, reproduction, diet, growth, mortality, pricing and markets of each geographical region and the hake species found there. With chapters written by regional experts on hake species and included within Wiley-Blackwell s prestigious Fish and Aquatic Resources Series, Hakes: Biology and Exploitation provides up-to-date and comparative information, including new approaches to fisheries management, for all those involved in fisheries management, aquatic ecology and biological sciences.

Paul Stanton Kibel
R1,032 Discovery Miles 10 320 Ships in 10 - 15 working days

There are many people and places connected to rivers: fishermen whose livelihood depends on river ecosystems, farms that need irrigation, indigenous groups whose cultures rely on fish and flowing waters, cities whose electricity comes from hydroelectric dams, and citizens who seek wild nature. For all of these people, instream flow is vitally important to where and how they live and work. Riverflow reveals the diverse and creative ways people are using the law to restore rivers, from the Columbia, Colorado, Klamath and Sacramento-San Joaquin watersheds in America, to the watersheds of the Tweed in England and Scotland, the Fraser in Canada, the Saru in Japan, the Nile in North Africa, and the Tigris-Euphrates in the Middle East. Riverflow documents that we already have the legal tools to preserve the ecological integrity of our waterways; the question is whether we have the political will to deploy these tools effectively.

New Directions in Agrarian Political Economy - Global Agrarian Transformations, Volume 1 (Hardcover): Ryan Isakson New Directions in Agrarian Political Economy - Global Agrarian Transformations, Volume 1 (Hardcover)
Ryan Isakson
R4,637 Discovery Miles 46 370 Ships in 10 - 15 working days

How relevant are the classic theories of agrarian change in the contemporary context? This volume explores this question by focusing upon the defining features of agrarian transformation in the 21st century: the financialization of food and agriculture, the blurring of rural and urban livelihoods through migration and other economic activities, forest transition, climate change, rural indebtedness, the co-evolution of social policy and moral economies, and changing property relations. Combined, the eleven contributions to this collection provide a broad overview of agrarian studies over the past four decades and identify the contemporary frontiers of agrarian political economy. In this path-breaking collection, the authors show how new iterations of long evident processes continue to catch peasants and smallholders in the crosshairs of crises and how many manage to face these challenges, developing new sources and sites of livelihood production. This volume was published as part one of the special double issue celebrating the 40th anniversary of the Journal of Peasant Studies.

R1,890 Discovery Miles 18 900 Ships in 10 - 15 working days

This book is the first to present in a systematic manner the application of game theory to fisheries management at both international and national levels. Strategic interaction among fishers and nations exploiting fishery resources is an inescapable fact of life. This has long been recognized at the international level, and is becoming increasingly recognized at the national/regional level. It follows, therefore, that, in order to be able to analyse effectively the management of these resources, the theory of strategic interaction game theory must be brought to bear. In this book the step-by-step development of the game theory is accompanied by numerous applications to the real world of fisheries management policy. As such, it is designed to appeal to policy makers and stakeholders, as well as to graduate students in Economics.

A Primer of Ecological Aquaculture (Paperback): Dietmar Kultz A Primer of Ecological Aquaculture (Paperback)
Dietmar Kultz
R1,426 Discovery Miles 14 260 Ships in 9 - 17 working days

Aquaculture exemplifies the ongoing global struggle to strike a sustainable balance between the conflicting needs of a rapidly increasing world population, human health, ecosystem health, the welfare of wild and domesticated animals, and the economic principles of globalized economies. On the one hand, aquaculture has great potential for providing us with a healthy and nutritious food supply whilst alleviating pressure on captive fisheries and reducing fisheries-induced habitat destruction, overfishing, genetic modification of wild populations, and wholesale waste of bycatch. On the other hand, aquaculture relies heavily on clean water, an increasingly precious (and dwindling) resource that is subject to intense pressure of being used for many competing objectives. This concise primer introduces students to the basic concepts, opportunities, and challenges of aquaculture with an emphasis on ecological considerations. It provides a critical assessment of current aquaculture practices from a broad, interdisciplinary perspective and from the standpoint of how best to align the two major (and often conflicting) goals of future aquaculture development: minimizing reliance on ecosystem services whilst maximizing productivity. A Primer of Ecological Aquaculture provides an accessible and authoritative overview for a wide range of undergraduate majors ranging from biology, engineering, and environmental policy to business and management. It will also appeal to a more general academic audience who wish to gain a current overview of the field.

This paper assists African countries and Regional Economic Communities (RECs) in improving the integration of the fisheries and aquaculture sector into policy documents dealing with poverty eradication, foreign currency generation, food security, the ecosystem approach to fisheries and aquaculture, and gender mainstreaming. For this purpose, the paper assesses whether the sector is adequately embedded in policy documents in Africa at both the country and regional level. The analysis addressed 54 African countries and 8 RECs. As a policy assessment tool, the multi-criteria analysis has been applied to compare two options - "relevance" and "inclusion" - across several performance dimensions. Based on the assessments performed, the extent of "integration" and "discrepancy" of the fisheries and aquaculture sector in policy documents has been calculated.The findings showed countries where the relevance of fisheries and aquaculture is not recognized, and where advocacy should be oriented towards raising awareness of the contribution of this sector. On the other hand, there are countries with a modest fisheries and aquaculture sector that have nevertheless implemented policies and reached high levels of inclusion. Recommendations both at country and REC level include improving the availability of information on the sector's value chain to enhance visibility and awareness of its importance.
