Fisheries resources are an important component of natural resources. It is an important source of high-quality animal protein and food for humans, which provides employment, economic benefits and social welfare for people engaged in fishing activities. It also has played an important role in food safety, economic development, and foreign trade. Fisheries resources economics is an important branch of both applied economics and resource economics. Its research object is fishery resources and its economic problems. The economics of fishery resources is to focus on the relationship between the demand for human economic activities and the supply of fishery resources, as well as between fishery resources and its development. This book expounds the reasons for the economic problems of fishery resources and the theoretical principles for solving them, so as to reveal the objective rules of the allocation of fishery resources in different regions and at different times, to coordinate the relationship between the utilization of fishery resources and economic development, and to realize the sustainable development of fishery economy. This book will also provide learning materials for undergraduates, graduate students and practitioners engaged in fishery resources development and scientific management.

Many raptors, the hawks, eagles, and falcons of the world, migrate over long distances, often in impressively large numbers. Many avoid crossing wide expanses of water and follow "flyways" to optimize soaring potential. Atmospheric conditions and landscape features, including waterways and mountain ranges, funnel these birds into predictable bottlenecks through which thousands of daytime birds of prey may pass in a short time. Birders and ornithologists also congregate at these locations to observe the river of raptors passing overhead (as did hunters in the United States in the past and in some countries even today).

Keith L. Bildstein has studied migrating raptors on four continents and directs the conservation science program at Hawk Mountain Sanctuary, Pennsylvania, the world's first refuge for migratory birds of prey. In this book, he details the stories and successes of twelve of the world's most important raptor-viewing spots, among them Cape May Point, New Jersey; Veracruz, Mexico; Kekoldi, Costa Rica; the Strait of Gibralter, Spain; and Elat, Israel. During peak migration, when the weather is right, the skies at these sites, as at Hawk Mountain, can fill with thousands of birds in a single field of view. Bildstein, whose knowledge of the phenomenon of raptor migration is comprehensive, provides an accessible account of the history, ecology, geography, science, and conservation aspects surrounding the migration of approximately two hundred species of raptors between their summer breeding sites and their wintering grounds. He summarizes current knowledge about how the birds' bodies handle the demands of long-distance migration and how they know where to go.

Migrating Raptors of the World also includes the ecological and conservation stories of several intriguing raptor migrants, including the Turkey Vulture, Osprey, Bald Eagle, Western Honey Buzzard, Northern Harrier, Grey-faced Buzzard, Steppe Buzzard, and Amur Falcon.

The Bahia Blanca Estuary is one of the largest coastal systems in Atlantic South America. This mesotidal estuary, situated in a sharp transition between humid subtropical and semiarid climates, has a unique combination of large interannual climatic variations. The estuarine area encompasses roughly 2300 square kilometers and is composed of wide expanses of intertidal flats, salt marshes, and emerged islands, which create intricate landscape patterns. Natural environments in the estuary sustain a high concentration of marine and terrestrial species, including endemic, threatened, and endangered fish and shorebirds. Puerto Cuatreros, in the inner zone of the estuary, hosts a permanent marine research station, whose records span more than 30 years of biophysical variables, and represent one of the largest time series of ecological data in South America. Beyond its ecological relevance, the Bahia Blanca Estuary is under increasing anthropogenic pressure from large urban settlements, industrial developments and harbors, raising the question of how to balance conservation and development. The Bahia Blanca Estuary: Ecology and Biodiversity offers a comprehensive review of life in the ecosystems of the estuary. The book is divided into five major sections, the first of which provides a description of the regional setting and covers key aspects of estuarine dynamics. The three following sections are dedicated to different habitat types and, within each section, the chapters are organized around major functional groups from pelagic and benthic environments. The fifth and final section covers issues related to management and conservation. Overall, the book provides essential and up-to-date reference material on the biodiversity and ecosystem processes of the Bahia Blanca Estuary, and will appeal to a broad international audience.

A "courageous and revelatory memoir" (Naomi Klein) chronicling the life of the leading Indigenous climate change, cultural, and human rights advocate For the first ten years of her life, Sheila Watt-Cloutier traveled only by dog team. Today there are more snow machines than dogs in her native Nunavik, a region that is part of the homeland of the Inuit in Canada. In Inuktitut, the language of Inuit, the elders say that the weather is Uggianaqtuq-behaving in strange and unexpected ways. The Right to Be Cold is Watt-Cloutier's memoir of growing up in the Arctic reaches of Quebec during these unsettling times. It is the story of an Inuk woman finding her place in the world, only to find her native land giving way to the inexorable warming of the planet. She decides to take a stand against its destruction. The Right to Be Cold is the human story of life on the front lines of climate change, told by a woman who rose from humble beginnings to become one of the most influential Indigenous environmental, cultural, and human rights advocates in the world. Raised by a single mother and grandmother in the small community of Kuujjuaq, Quebec, Watt-Cloutier describes life in the traditional ice-based hunting culture of an Inuit community and reveals how Indigenous life, human rights, and the threat of climate change are inextricably linked. Colonialism intervened in this world and in her life in often violent ways, and she traces her path from Nunavik to Nova Scotia (where she was sent at the age of ten to live with a family that was not her own); to a residential school in Churchill, Manitoba; and back to her hometown to work as an interpreter and student counselor. The Right to Be Cold is at once the intimate coming-of-age story of a remarkable woman, a deeply informed look at the life and culture of an Indigenous community reeling from a colonial history and now threatened by climate change, and a stirring account of an activist's powerful efforts to safeguard Inuit culture, the Arctic, and the planet.

Among the deep-sea marine invertebrates, pycnogonids and crustaceans represent ecologically important and most diverse groups of species. Yet both are still poorly understood. Sampling and exploring operations off the west and east coast of the Americas has significantly increased in the last two decades. However such operations are very costly and limited in number and frequency. In countries like Brazil, Canada, Chile, Colombia, Costa Rica, Mexico, Peru, the United States of America, and El Salvador a large effort has been made to explore the deep-sea resources and the rich diversity of the communities, resulting in a better understanding of the natural ecosystems on both coasts of America. Pycnogonids and many groups of deep-sea crustaceans have been intensively studied, from the smallest animals, like the mostly unknown benthic copepods to the largest decapods. This book presents new and updated information on various groups of deep-sea pycnogonids and crustaceans occurring off the American continent. Offering a valuable reference resource for scientists interested in this fascinating fauna, it includes review papers and new data on the deep-sea communities occurring off the USA, Mexico, El Salvador, Costa Rica, Colombia, Chile, Peru, Brazil and Argentina, as well as in larger areas in both the East Pacific and the West Atlantic. As such it covers most of the current deep-water research in Latin America.

It's the dream scenario for many of us after a long week: having the house completely to ourselves. No partners, no parents, no kids, no pets. But as we settle into the couch, something stirs: maybe a mouse darts out from under a cupboard, or a fly buzzes lazily past the window. We're not actually alone at all. Until quite recently, no one had taken the life that lives with us very seriously: until Rob Dunn and his team decided to take a closer look. Upon investigating the terra incognita of our homes, they discovered that there are nearly 200,000 species living in our bedrooms, kitchens, living areas, bathrooms, and basements. Some of these species can kill us. Some benefit us. And some seem simply benign. But almost all of them were completely unknown--and they've been living alongside us the whole time. In Never Home Alone, biologist Rob Dunn takes us to the edge of biology's latest frontier: our own homes. Every house is a wilderness--from the Egyptian meal moths in our cupboards, to the camel crickets living in the basement, to the antibiotic-resistant Staphylococcus waiting on the kitchen counter, thousands of species of insects, bacteria, fungi, and plants live literally under our noses. As we have become increasingly obsessed with cleaning and sterilizing our homes and separating our living spaces from nature, we have unwittingly cultivated an entirely new playground for evolution. Unfortunately, this means that we have created a range of new parasites, from antibiotic-resistant microbes to nearly impossible to kill cockroaches, to threaten ourselves with. At the same time, many of the more helpful organisms--such as microbes that can protect us from autoimmune diseases or promote healthy digestion, or the centipedes that can hunt down those pesky roaches--are caught in the crosshairs. If we're not careful, the "healthier" we try to make our homes, the more likely we'll be putting our own health at risk. A rich natural history and a thrilling scientific investigation, Rob Dunn's Never Home Alone shows us that if are to truly thrive in our homes, we must learn to welcome the unknown guests that have been there the whole time.

This is the ninth volume of ten in the The Natural History of the Crustacea Series. The chapters in this volume synthesize the diverse topics in fisheries and aquaculture. In the first part of the book, chapters explore worldwide crustacean fisheries. This section comes to a conclusion with two chapters on harvested crustaceans that are usually not within the focus of the mainstream fisheries research, possibly because they are caught by local fishing communities in small-scale operations and sold locally as subsistence activity. In the second part of the book, the authors explore the variety of cultured crustacean species, like shrimps, prawns, lobsters, and crabs. Chapters in the third part of the volume focus on important challenges and opportunities, including diseases and parasitism, the use of crustacean as bioindicators, and their role in biotechnology.

THE TIMES, ECONOMIST AND GUARDIAN BOOKS OF THE YEAR 2017 It is accepted wisdom today that human beings have irrevocably damaged the natural world. Yet what if this narrative obscures a more hopeful truth? In Inheritors of the Earth, renowned ecologist and environmentalist Chris D. Thomas overturns the accepted story, revealing how nature is fighting back. Many animals and plants actually benefit from our presence, raising biological diversity in most parts of the world and increasing the rate at which new species are formed, perhaps to the highest level in Earth's history. From Costa Rican tropical forests to the thoroughly transformed British landscape, nature is coping surprisingly well in the human epoch. Chris Thomas takes us on a gripping round-the-world journey to meet the enterprising creatures that are thriving in the Anthropocene, from York's ochre-coloured comma butterfly to hybrid bison in North America, scarlet-beaked pukekos in New Zealand, and Asian palms forming thickets in the European Alps. In so doing, he questions our irrational persecution of so-called 'invasive species', and shows us that we should not treat the Earth as a faded masterpiece that we need to restore. After all, if life can recover from the asteroid that killed off the dinosaurs, might it not be able to survive the onslaughts of a technological ape? Combining a naturalist's eye for wildlife with an ecologist's wide lens, Chris Thomas forces us to re-examine humanity's relationship with nature, and reminds us that the story of life is the story of change.
