The Pearl Oyster Summary:

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

Pearl Oyster Health Management Summary:

The pearl oyster industry is a growing multibillion dollar sector of mollusk aquaculture. Pearl farming occurs throughout Australasia, the Middle East and South America. Few species of mollusks possess the ability to produce pearls of gem quality. The South Sea pearl oyster is one of them. Pearl production in the wild is an unpredictable and uncontrolled event which human intervention, through pearl culture, has progressively overcome by improving culture practices. Farming mother-of-pearls shares commonalties with edible mollusk aquaculture. However, the endproduct, pearl production, is unique to this sector. In aquatic production, heal issues are of utmost importance; pearl production is based entirely upon health. The pearl itself is a product of the oyster's immune defenses as a response to soft-tissue irritation. Exploited stocks receive frequent handling stresses which often predispose farmed animals to infection and diseases. Therefore, the importance of health management for pearl oysters is paramount. Today, most disease problems are caused by opportunistic pathogens taking advantage of oysters weakened by the stress of handling, including pearl surgery and sub-optimal growing conditions. Except for the mass mortalities experienced in Japan, the pearl oyster industry have not yet faced the types of epizootics which has impacted mollusk culture elsewhere in the world. Development of the industry will, inevitably, lead to increased risk of disease introduction, spread or emergence. Against such an unwanted future, health management is the critical defense line. The objectives of this technical paper are to: (i) review pearl oyster mortalities and disease problems in order to help design programs aimed at reducing the risks from diseases; and (ii) provide technical guidance to pearl oyster farmers and the industry on management of pearl oyster health so that sector development will be sustainable not only in providing huge employment to communities where pearl

Biomineralization Mechanism of the Pearl Oyster Pinctada fucata Summary:

This book presents an overview of our current understanding of the biomineralization mechanisms for shell formation in the pearl oyster Pinctada fucata, based on molecular biology, biochemistry, cell biology, structural biology and environmental biology. Pinctada fucata is the major pearl-producing shellfish in the South China Sea and is also an established model system for the research on the nacre biomineralization mechanism. Extensive studies on nacre biomineralization have provided valuable information for novel bionic material design. Discussing the isolation and gene cloning of the matrix proteins involved in the shell formation, as well as the cell signaling pathways, shell microstructures, and the environmental impacts on shell biomineralization, it is a valuable reference resource for researchers working in the field of nacre biomineralization and biomaterials.
