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.

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.

Daniel Pauly is the most widely cited fisheries scientist of his generation. On the Sex of Fish and the Gender of Scientists comprises an edited and updated collection of 27 of Daniel Pauly's essays, spanning a great range of exciting and sometimes controversial topics, many of them breaking new scientific ground.

The culmination of over a decade's worth of research by the Pond Dynamics/Aquaculture Collaborative Research Support Program (CRSP), Dynamics of Pond Aquaculture not only explains the physical, chemical, and biological processes that interact in pond culture systems, but also presents real-world research findings and considers the people who depend on these systems. This book uses data from CRSP field research sites in East Africa, Southeast Asia, Central America, and North America to present a complete picture of the pond system and the environment in which it exists.
A thorough study of the principles and practices of aquaculture, the book reflects the state of the art in pond aquaculture and incorporates recent advances that have changed the science in the last decade or so. It provides a thorough review of the many methods, techniques, and ideas that comprise this complex and fascinating area of study.

The basic principle of all molecular genetic methods is to employ inherited, discrete and stable markers to identify genotypes that characterize individuals, populations or species. Such genetic data can provide information ori the levels and distribution of genetic variability in relation to mating patterns, life history, population size, migration and environment. Although molecular tools have long been employed to address various questions in fisheries biology and management, their contributions to the field are sometimes unclear, and often controversial. Much of the initial impetus for the deployment of molecular markers arose from the desire to assess fish stock structure based on various interpretations of the stock concept. Although such studies have met with varying success, they continue to provide an impetus for the development of increasingly sensitive population discriminators, yielding information that can be valuable for both sustainable exploitation and the conservation of fish populations. In the last major synthesis of the subject, Ryman and Utter (1987) summarized progress and applications, though this was prior to the wide-scale adoption of DNA methodology. New sources of genetic markers and protocols are now available, in particular those that exploit the widely distributed and highly variable repeat sequences of DNA, and the amplification technique of the polymerase chain reaction.

A How-To Guide for Conducting Common Fisheries-Related Analyses in R Introductory Fisheries Analyses with R provides detailed instructions on performing basic fisheries stock assessment analyses in the R environment. Accessible to practicing fisheries scientists as well as advanced undergraduate and graduate students, the book demonstrates the flexibility and power of R, offers insight into the reproducibility of script-based analyses, and shows how the use of R leads to more efficient and productive work in fisheries science. The first three chapters present a minimal introduction to the R environment that builds a foundation for the fisheries-specific analyses in the remainder of the book. These chapters help you become familiar with R for basic fisheries analyses and graphics. Subsequent chapters focus on methods to analyze age comparisons, age-length keys, size structure, weight-length relationships, condition, abundance (from capture-recapture and depletion data), mortality rates, individual growth, and the stock-recruit relationship. The fundamental statistical methods of linear regression, analysis of variance (ANOVA), and nonlinear regression are demonstrated within the contexts of these common fisheries analyses. For each analysis, the author completely explains the R functions and provides sufficient background information so that you can confidently implement each method. Web Resource The author's website at http://derekogle.com/IFAR/ includes the data files and R code for each chapter, enabling you to reproduce the results in the book as well as create your own scripts. The site also offers supplemental code for more advanced analyses and practice exercises for every chapter.

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 over 22000 living species of teleosts, including nearly all the fish of importance in commercial fisheries and aquaculture. Teleosts are represented in just about every conceivable aquatic environment from temporary desert pools to the deep ocean, from soda lakes to sub-zero Antarctic waters. Behaviour forms the primary interface between these effective survival machines and their environ ment; behavioural plasticity is the key to the success of the teleost fishes. In the decade before the publication of the first edition of this book (1986) the study of animal behaviour underwent revolutionary changes under the dual impact of the new fields of behavioural ecology and sociobiology. Quantitative, experimentally-verifiable hypotheses about why individual animals behave were formulated for the first time and met with considerable success. Much of the early work in these new fields concentrated on birds and mammals, but material presented in the first edition of this book helped to demonstrate that fish behaviour is not just a simplified version of that seen in birds and mammals. but obeys the same ecological and evolutionary rules. In the five years since the first edition. much of the early theory has matured: optimal solutions to the problems of feeding and mating require subtle trade-offs of energy balance."

The impact of man on the biosphere is profound. Quite apart from our capacity to destroy natural ecosystems and to drive species to extinction, we mould the evolution of the survivors by the selection pressures we apply to them. This has implications for the continued health of our natural biological resources and for the way in which we seek to optimise yield from those resources. Of these biological resources, fish stocks are particularly important to mankind as a source of protein. On a global basis, fish stocks provide the major source of protein for human consumption from natural ecosystems, amounting to some seventy million tonnes in 1970. Although fisheries management has been extensively developed over the last century, it has not hitherto considered the evolutionary consequences of fishing activity. While this omission may not have been serious in the past, the ever increasing intensity of exploitation and the deteriorating health of fish stocks has generated an urgent need for a better understanding of evolution driven by harvesting and the implications of this for fish stock management. The foundations for this understanding for the most part come from recent developments in evolutionary biology and are not generally available to fisheries scientists. The purpose of this book is to provide this basis in a form that is both accessible and relevant to fisheries biology.

Tilapia culture is currently practiced in 95 countries all over the world and the number is expected to increase.

It also highlights and presents the experiences of leading countries in tilapia culture.

This is intended as an introduction for advanced undergraduates and postgraduates in marine ecology, freshwater ecology, fish biology, fisheries ecology and aquaculture. It adopts a habitat-based approach, ranging from head waters to ocean depths, and from tropics to polar regions, thereby loosely reflecting the organization of general ecology textbooks and demonstrating how the principles of contemporary ecology can be applied to fishes.

Over the last decade, the study of shark biology has benefited from the development, refinement, and rapid expansion of novel techniques and advances in technology. These have given new insight into the fields of shark genetics, feeding, foraging, bioenergetics, imaging, age and growth, movement, migration, habitat preference, and habitat use. This pioneering book, written by experts in shark biology, examines technologies such as autonomous vehicle tracking, underwater video approaches, molecular genetics techniques, and accelerometry, among many others. Each detailed chapter offers new insights and promises for future studies of elasmobranch biology, provides an overview of appropriate uses of each technique, and can be readily extended to other aquatic fish and marine mammals and reptiles. Including chapter authors who were pioneers in developing some of the technologies discussed in the book, this book serves as the first single-source reference with in-depth coverage of techniques appropriate for the laboratory and field study of sharks, skates, and rays. It concludes with a unique section on Citizen Science and its application to studies of shark biology. This is a must-read for any marine biologist or scientist working in the field of shark biology, as well as marine biology students and graduates.

The Alantic salmon (Salmo salar) is a fish of major biological interest and economic importance. Recent years have witnessed major advances in the understanding of the many facets of the biology, ecology and management of this fish. The author, Dr Derek Mills, covers all major aspects of the atlantic salmon throughout its geographical range in the northern hemisphere. There is a great awareness today of the effects on the salmon of afforestation, pollution, acid rain, water abstraction and changing agricultural methods. There has also been a rapid escalation of salmon farming which is beginning to have an impact on wild stocks. The author discusses these issues, also considering the increasing threat of over exploitation of the atlantic salmon.

Following the publication of seminal papers by professors H. S. Gordon in 1954 and A. D. Scott in 1955, active research has led to rapid progress in our understanding of the economics of fisheries. Fishing, however, is a complicated activity involving intricate interactions between man-made fishing capital and naturally produced fish stocks in an inherently dynamic and stochastic setting. Consequently, in spite of significant advances, important sections of fisheries economics remain largely unexplored. One such area is the economics of migratory fish stocks. In 1985, the editors of this volume embarked on a research project concerned with the optimal utilization of common Nordic fish stocks. A fundamental feature of some of the most important of these fish stocks, such as the Atlanto-Scandian herring and the Icelandic capelin, is their migratory behaviour. Not only do the migrations continuously alter the economic conditions for harvesting these species. They also result in the periodical transfer of stock concentrations from one exclusive fisheries jurisdictions to another. It was readily apparent that this behaviour constituted a crucial determinant of the appropriate harvesting pattern of these stocks. More importantly, however, migrations are by no means a unique feature of Nordic fish stocks. In fact, it appears that migratory behaviour is exhibited, albeit in varying degrees, by all species of fish. It therefore stands to reason that migrations constitute an important aspect of the economics of fisheries in general.

A revision of this introduction to the study of the sea, the second edition has been expanded and reorganized, with many new figures and tables. Every chapter has been updated and many have been rewritten. A new chapter on man's use of the oceans has been included to cover satellites and position fixing, renewable energy sources in the sea, seabed minerals, oil and gas, pollution and maritime law. In this edition, the authors refer to original references and review articles, so that readers can find their way into the literature more easily. The text draws on examples from a wide range of seas.

"McGoodwin critically examines accepted fisheries management practices and advocates alternative approaches that would situate the social and economic needs of fishers at the forefront of policy considerations. Yet, the book is much more than that. As the title indicates, McGoodwin's book is sweeping in its coverage. It addresses virtually every aspect of fisheries--cultural, economic, political, and environmental. . . . It is a good introductory book for persons, no matter their discipline or profession, who are interested in natural resource management. . . . On the other hand, McGoodwin has provided a valuable service for all by pulling together in one place an extensive and timely review of the fisheries literature."--Natural Resources and Environmental Administration
"It is difficult to disagree with McGoodwin's overall argument: contemporary fisheries management must change. His book provides a broad review of fisheries management policies and an important prescription for an ailing industry and way of life. It is written in a style that commends itself to fishers, fisheries managers, and academics alike. It is an important book whose audience is sure to extend far beyond the bounds of maritime anthropologists."--American Anthropologist

"... this book is the first to describe, in detail, the art and science of coral reef restoration. It is to be hoped that the information that can be gleaned within the pages of this book will set a path towards continued preservation of this valuable underwater treasure to be used, appreciated, and experienced for future generations." -- Senator Bob Graham (retired), Miami Lakes, Florida, from the Foreword Most of what we know about the rehabilitation of coral reef systems stems from efforts to repair reefs injured by vessels that have run aground. To date, however, there is a paucity of published literature regarding the efficacy and/or failure of coral reef restoration techniques. While most of the literature that is available comes from meeting abstracts, workshops and technical memoranda, these papers and reports have forged a scientific framework that can help guide future efforts. The Coral Reef Restoration Handbook is the first published volume devoted to the science of coral reef restoration. It offers a scientific, conceptual framework along with practical strategies for reef assessment and restoration. Contributors from a variety of disciplines discuss engineering, geological, biological, and socioeconomic factors to create a text that is designed to guide scientists and resource managers in the decision-making process from initial assessment of the injury through conceptual restoration design, implementation, and monitoring. An excellent selection of relevant case studies is utilized to illustrate concepts and challenges inherent in the process of restoration. This volume gives reef scientists and managers the opportunity to glean significant information from previous efforts. It provides them with the opportunity to build on the lessons learned and develop successful restoration efforts into the future.

The author spent much of 1989 and 1990 living within the Muscovite community and came into contact with people at all levels, from pimps to philosophers. He provides a portrait of a society which is struggling to survive the traumas and changes of the Gorbachev years. In some ways more medieval and Oriental than modern and Western, Moscow is a city in which tales of flying saucers and masonic conspiracies co-exist with endless queues, corruption, anti-semitism and a black market in guns. Durden-Smith also discovered in Moscow an intellectual passion and energy which puts most Western capitals to shame and which makes Moscow not only one of the most important, but also one of the most complex, contradictory and fascinating cities on earth.

This volume provides an abundance of valuable first-hand information about the diversity, biology, ecology culture of the portunid crabs of the word seas. Marine crabs play an important role directly or indirectly in the livelihood of millions of people around the world. They have been reported to make up about 20% of all marine crustaceans caught, farmed, and consumed worldwide. Among these marine crabs, portunid crabs (or swimming crabs of the family Portunidae) assume greater significance in the marine industry, owing to their delicate meat with nutritional qualities. Although several species of portunid crabs are edible and commercially important, only a few species have been widely cultivated. This is largely due to the lack of information on the biology of portunid crabs. Keeping this in view, this volume presents the biology and aquaculture of marine portunid crabs. This volume will be of great use for researchers and students of disciplines such as fisheries science, marine biology, aquatic biology and fisheries, and zoology, and will also serve as a standard reference for college, university, and research libraries around the world.

Becoming Salmon is the first ethnographic account of salmon aquaculture, the most recent turn in the human history of animal domestication. In this careful and nuanced study, Marianne Elisabeth Lien explores how the growth of marine domestication has blurred traditional distinctions between fish and animals, recasting farmed fish as sentient beings, capable of feeling pain and subject to animal-welfare legislation. Drawing on fieldwork on and off salmon farms, Lien follows farmed Atlantic salmon through contemporary industrial husbandry, exposing how salmon are bred to be hungry, globally mobile, and "alien" in their watersheds of origin. Attentive to both the economic context of industrial food production and the materiality of human-animal relations, this book highlights the fragile and contingent relational practices that constitute salmon aquaculture and the multiple ways of "becoming salmon" that emerge as a result.

Pathology and Epidemiology of Aquatic Animal Diseases for Practitioners Comprehensive reference on the diseases and applied epidemiology of all aquatic animal taxa, including invertebrates and vertebrates Pathology and Epidemiology of Aquatic Animal Diseases for Practitioners provides information on the diseases and applied epidemiology of all aquatic animal taxa, including invertebrates and vertebrates, along with information on applied epidemiology, acknowledging the One Health concept, and discussion on probabilities of disease outbreaks occurring and assesses the economic costs of treating those outbreaks, if applicable. Divided into two sections, the book looks at the pathology of major aquatic taxa and their associated infectious diseases—parasitic, viral, and bacterial—and non-infectious diseases. Each includes an overview, their host range and transmission, signs and diagnosis, differentials, and treatment and management. These assets are accompanied by clinical signs-lesion differential charts. Sample topics discussed in Pathology and Epidemiology of Aquatic Animal Diseases include: Echinoderms, including crinoidea (crinoids, sea lilies, feather stars, and asteroidea), sea stars/starfish, and ophiuroidea (brittle stars and basket stars) Reptiles, including turtles (freshwater and marine), crocodilians, marine iguanas, and sea snakes Pinnipeds, including otariidae (eared seals), odobenidae (walruses), phocidae (earless seals), mustelidae (otters), and sirenia (manatees and dugongs) Tropical marine aquarium fish (damselfish, angelfish, gobies, wrasses, parrotfish, butterfly fish, and clownfish) and anemones. A highly useful reference for veterinary practitioners, academic staff, and researchers, Pathology and Epidemiology of Aquatic Animal Diseases is also suitable for those who are interested in aquatic veterinary medicine and serves as a companion to Fundamentals of Aquatic Veterinary Medicine, written by the same editorial team.

"The chapters are organized well, and the preface explains how the concept of food is changing over time and how marine organisms are considered as healthy food." -P.N. Sudha, DKM College for Women, Tamil Nadu, India The relationship between food and health has been a growing concern in modern society, and the importance of information on their connection has elevated accordingly. People are becoming prone to diseases due to the deterioration of the environment. Despite a growing interest in preventative medicine in the healthcare sector, few medications can be called preventative drugs. Foods may exhibit completely different functions in a living body, depending on whether their components are simple substances providing energy and nutrition, or valid "functional entities." This book covers all aspects of healthcare solutions through marine-derived materials, with twenty-six chapters exploring an array of topics pertaining to human health in everyday life. Beginning with an introduction to food functionality and disease presentation, Chapters Two to Nine discuss chitin, chitosan, and the production and application of chitosan oligosaccharides regarding anti-cancer, anti-aging, and antioxidant activity. Furthermore, utilization of these cationic polysaccharides in artificial skin development, the prevention of alcohol consumption, dentistry, systemic diseases prevention and Alzheimer dementia are discussed in subsequent chapters. In Chapters Ten and Thirteen, I discuss obesity, osteoporosis, sexual dysfunction and sleep disorders using fisheries products. Additionally, Chapters Fourteen to Eighteen detail the use of marine algae to treat diabetics, allergy, asthma, AIDS and hair loss, as well as the use of fisheries products for hypertension and athlete's foot. Chapters Twenty-Two through Twenty-Six then shed light on the anti-aging effects of fish, the abundance of taurine in shellfish, antifreeze protein, food shortages through fish breeding, and cosmeceutical product development using marine organisms.

Research in modern experimental and theoretical population genetics has been strengthened by advances in molecular techniques for the analysis of genetic variability. The evolutionary relationships of organisms may be investigated by comparing DNA sequences. This book covers chapters on population genetics, DNA polymorphism, genetic homeostasis, and biochemical genetics, plus a chapter on phylogenetic tree construction. In addition, each chapter contains training materials with numerical examples.

This book provides a timely analysis of the role that information-particularly scientific information-plays in the policy-making and decision-making processes in coastal and ocean management. It includes contributions from global experts in marine environmental science, marine policy, fisheries, public policy and administration, resource management, risk management, and information management. The book is divided into four sections that provide focused analyses, including An overview of the characteristics of the science-policy interface, including a discussion of the role of scientific information in policy making and an argument that the term "science-policy interface" is inaccurate due to the existence of many possible interfaces Descriptions of fundamental concepts and principles for understanding the role of information in effective integrated coastal and ocean management National and international case studies that illustrate key factors in successful science-policy interfaces, such as awareness, communication, and use of information Critical issues and future research challenges The book also explores the different types of science-policy interfaces existing within and between different organizations, as well as the various roles that different types of non-governmental organizations play in producing and disseminating information. Science, Information, and Policy Interface for Effective Coastal and Ocean Management presents a wealth of knowledge that enhances current best practices to achieve more effective communication and use of marine environmental information. Useful to all major groups in the policy-making process, from senior policy- and decision-makers to practitioners in coastal and ocean management, it helps to increase understanding of catalysts and barriers to communicating research findings. It also serves as a starting point for further research and progress in efficient marine environment management. The Open Access version of this book, available at https://doi.org/10.1201/b21483, has been made available under a Creative Commons Attribution-Non Commercial-No Derivatives 4.0 license.

In recent years, citizen science has emerged as a powerful new concept to enable the general public, students, and volunteers to become involved in scientific research. A prime example is in biodiversity conservation, where data collection and monitoring can be greatly enhanced through citizen participation. This is the first book to provide much needed guidance and case studies from marine and coastal conservation. The novelty and rapid expansion of the field has created a demand for the discussion of key issues and the development of best practices. The book demonstrates the utility and feasibility, as well as limitations, of using marine and coastal citizen science for conservation, and by providing critical considerations (i.e.which questions and systems are best suited for citizen science), presents recommendations for best practices for successful marine and coastal citizen science projects. A range of case studies, for example, on monitoring of seabird populations, invasive species, plastics pollution, and the impacts of climate change, from different parts of the world, is included. Also included are discussions on engaging youth, indigenous communities, and divers and snorkelers as citizen scientists, as well as best practices on communication within citizen science, building trust with stakeholders, and informing marine policy as part of this exciting and empowering way of improving marine and coastal conservation. .
