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
“For the first time, fish became our companions and a corner of many a Victorian parlour was given over to housing tiny fragments of their world enclosed in glass.” The experience of seeing a fish swimming in a glass tank is one we take for granted now but in Victorian England this was a remarkable sight. People had simply not been able to see fish as they now could with the invention of the aquarium and everything that went with it. Goldfish in the Parlour looks at the boom in the building of public aquariums, as well as the craze for home aquariums and visiting the seaside, during the reign of Queen Victoria. Furthermore, this book considers how people see and meet animals and, importantly, in what institutions and in what contexts these encounters happen. John Simons uncovers the sweeping consequences of the Victorian obsession with marine animals by looking at naturalist Frank Buckland’s Museum of Economic Fish Culture and the role of fish in the Victorian economy, the development of angling as a sport divided along class lines, the seeding of Empire with British fish and comparisons with aquarium building in Europe, USA and Australia. Goldfish in the Parlour interrogates the craze that took over Victorian England when aquariums “introduced” fish to parks, zoos and parlours.
