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

Since early 1989, a gem dealer I've known for years has been calling me every few weeks to brief me on mounting mayhem in Colombia's lucrative emerald market. The troubling gist of these calls is always this: There is a full-fledged turf war going on between that South American country's bustling drug and gem trades for control of its emerald ex port business. According to this dealer and several others, anywhere from two to four thousand emerald industry people, mostly miners and deal ers, have been murdered since 1980. No doubt the gem sector, itself never gun shy, has retaliated in full and in kind. After all, the two groups have banded together in an intermittent alliance against a common enemy-Communist guerillas-with results the CIA would envy. I mention this bloodshed because of something the gem dealer once said to me: "I bet you never think of what a gem has to go through to get to a jewelry store:' He's right. I tend to think of colored stones as things of beauty, not objects of gruesome power struggles between mining kingpins and drug lords. Can you blame me, or anyone with insider knowledge, if a gem sheds any connection with its past once sculpted by a cutter into the glittering mar vel we see in a jeweler's showcase? Like Odysseus listening to the sirens' song, we become victims of an aesthetics-induced amnesia.

Aquaculture Pathophysiology, Volume II. Crustacean and Molluscan Diseases is a concise, practical reference on shellfish diseases of significant risk to aquaculture. Its value to the veterinarian, fish health biologist or extensionist, fish pathologist and fish health diagnostician is its easy reach for critical information on the diagnosis and management of significant infectious and non-infectious diseases for the major temperate, subtropical and tropical shellfish species of commercial and fisheries importance. This volume should be read in partnership with volume one on finfish diseases as the principles and approach to the diagnosis and management of aquacultured animal species are similar. This comprehensive resource is ideal for researchers, teachers, students, diagnostic laboratory scientists, aquaculture technicians, and farmers who need to be competent across both finfish and shellfish health issues. Presents a focus on the disease process of major or emerging viral, bacterial, fungal and parasitic infections affecting aquacultured shellfish species e.g., shrimp, lobsters, crayfish, crabs, oysters, mussels, abalone and scallops Focuses on important or emerging environmental, nutritional, genetic, deformity, toxicological, endocrine disruption, and neoplastic diseases in crustaceans and mollusks Provides a review of the immunology of shellfish relevant to a practical understanding of disease diagnosis and management Includes an overview of laboratory diagnostic methods relevant to the detection of shellfish diseases Discusses the diverse risk factors of shellfish diseases and options for their control

Pearl powder is made from freshwater pearls or saltwater pearls below jewellery grade. These are sterilised in boiling water and then milled into a fine powder using stainless steel grinding discs or by milling with small porcelain balls in moist conditions. The powder is sold as such or mixed into creams. Pearl powder is widely believed to help improve the appearance of the skin, and is used as a cosmetic by royal families in Asia. It is also used as a treatment for acne. Some studies have claimed that pearl powder can stimulate the skin's fibroblasts, help regenerate collagen, and accelerate healing of certain skin conditions, wounds, and burns. This book seeks to introduce the benefits of pearl powders and to highlight the potential of this advanced material.
