Contrary to a generally held view that pearls are found by chance in oysters, almost all are now produced from farms. This book is a comprehensive treatment of all aspects of the biology of pearl oysters, their anatomy, reproduction, genetics, diseases, etc. It considers how they are farmed from spawning and culturing larvae in hatcheries to adults in the ocean; how various environmental factors, including pollution affect them; and how modern techniques are successfully producing large numbers of cultured pearls. This is the ultimate reference source on pearl oysters and the culture of pearls, written and edited by a number of scientists who are world experts in their fields. - Comprehensive treatment of pearl oyster biology and pearl culture - Written by the top world authorities - Highly illustrated and figured - Of practical relevance to a broad readership, from professional biologists to those involved in the practicalities and practice of pearl production

Before New York City was the Big Apple, it could have been called the Big Oyster. Now award-winning author Mark Kurlansky tells the remarkable story of New York by following the trajectory of one of its most fascinating inhabitants–the oyster, whose influence on the great metropolis remains unparalleled. For centuries New York was famous for its oysters, which until the early 1900s played such a dominant a role in the city’s economy, gastronomy, and ecology that the abundant bivalves were Gotham’s most celebrated export, a staple food for the wealthy, the poor, and tourists alike, and the primary natural defense against pollution for the city’s congested waterways. Filled with cultural, historical, and culinary insight–along with historic recipes, maps, drawings, and photos–this dynamic narrative sweeps readers from the island hunting ground of the Lenape Indians to the death of the oyster beds and the rise of America’s environmentalist movement, from the oyster cellars of the rough-and-tumble Five Points slums to Manhattan’s Gilded Age dining chambers. Kurlansky brings characters vividly to life while recounting dramatic incidents that changed the course of New York history. Here are the stories behind Peter Stuyvesant’s peg leg and Robert Fulton’s “Folly”; the oyster merchant and pioneering African American leader Thomas Downing; the birth of the business lunch at Delmonico’s; early feminist Fanny Fern, one of the highest-paid newspaper writers in the city; even “Diamond” Jim Brady, who we discover was not the gourmand of popular legend. With The Big Oyster, Mark Kurlansky serves up history at its most engrossing, entertaining, and delicious.

Since Antiquity the natural pearls of the Gulf have been famed as the finest, most lustrous and most plentiful that the world can offer. From the beginnings of trade until the 1930s, these pearls were a major product of the Gulf's coastal peoples. Latterly, from the 17th to the early 20th centuries, rising international demand turned pearling into their economic mainstay. By this time pearls were fished in their millions, and pearling became the pillar of the regional economy, dominating the lives, health and expectations of entire shaikhdoms. The influx of people and wealth to the coast permanently transformed the Gulf, providing the manpower and capital to germinate and nurture the city-states - notably Kuwait, Bahrain, Qatar, Abu Dhabi, Dubai, Sharjah and Ras al-Khaimah - which endure there today. Despite its formative role, there has until now been no book taking the entire history of pearling as its subject. Dr Carter's ground-breaking work traces its evolution on both the Arabian and the Persian sides of the Gulf, and explores the role it played in shaping the political, social and urban configuration that we see in the region today. It shows the extent to which the Gulf economy became dependent on a single commodity, and how, in that respect, pearling resembled the oil industry that would replace it. Lavishly illustrated, this book covers in unprecedented detail the history, development, conduct, florescence and catastrophic collapse of the industry in the early 20th century. It will fascinate not only those wishing to understand the growth and conduct of the pearl fishery, but also those interested in the history of the region and the origins of the Gulf states, and in the colourful story of the global taste for one of mankind's most highly prized precious stones.

This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.

This is a new edition of the classic textbook on marine protected area (MPA) management in the tropics, originally produced as an output of the Bali World Parks Congress in 1982. Approaches to planning and managing MPAs have evolved considerably. Major advances include innovative financing mechanisms, partnerships with the private sector and NGOs, and collaborative management between government and coastal communities. These advances have brought new approaches for MPA establishment and management that are more participatory, involving communities through interaction and collaboration rather than prescription. With new case studies and illustrations, the guide comes in a water-resistant cover for field use. It is intended for those who plan individual and/or national MPA systems and gives philosophical context for MPAs along with some basic principles and approaches.
