Mantle regeneration in the pearl oysters Pinctada fucata and Pinctada margaritifera

open access: yes, 2005
Mantle tissue in pearl oysters (Pteriidae) is responsible for secreting the mother-of-pearl or nacre lining the shell. When grafted into another oyster, excised mantle tissue, commonly called ‘saibo’, is responsible for cultured pearl production.

Metabolic Response in the Gill Tissue of Juvenile Black-Shelled Pearl Oyster (Pinctada fucata martensii) under Salinity Stress

open access: yesFishes
Salinity significantly affects shellfish metabolism and growth. In this study, we evaluated the characterization of metabolomic differences in the juvenile black-shelled pearl oyster, Pinctada fucata martensii, under 15‰ (LSG), 25‰ (CG), and 35‰ (HSG ...

Pearl culture and pearl oyster cultivation

open access: yes, 1967
Few marine animals have yet been tamed and harnessed for man's use. Of these the bivalves have the greatest potential, and of the bivalves the pearl oysters are perhaps the most thoroughly exploited. Not only are they eaten and their shell put to use, but their nacre secreting properties are tapped to produce pearls by design, rather than by accident ...
