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.
