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

"The author views his topics and objectives from perspectives that have often been neglected. He attempts to provide elements for the incorporation of oxygen into a level- or domain-specific theory, capable of predicting the risk-minimizing behavior of fishes, both under food and oxygen constrains. His primary concerns focus on advancing a theory of growth."--Publisher's description.
