EVALUATION OF THE INDONESIAN PEARL AND PEARL OYSTER MARKET

Indonesian Aquaculture Journal
Evaluation of the Indonesian pearl market is still dominated by trade analysis, while integration of export data with field information on supply chains and market dynamics has been limited. This study aims to evaluate the pearl and pearl oyster (Pinctada maxima) market in Indonesia through an analysis of export trends, changes in trade value, and ...

Biochemical Studies on the Pearl-Oyster (Pinctada martensi)

Journal of the agricultural chemical society of Japan, 1949
The fresh meat was divided into 6 parts adductor muscle, internal organs, mantle, gill, pedestal and mucilage, and the glycogen contents were determined according to the season. Among the fresh meat, the glycogen content is largest in the adductor muscles. The glycogen content of the mantle, gill and pedestal remajns to be about the same throughout the

Molecular and morphological data provide evidence for only one alien species of pearl oyster in the Mediterranean Sea

Scientia Marina
Taxonomic identification of alien bivalve species in the Mediterranean Sea can be challenging because of high morphological variability and the occurrence of cryptic species complexes, as in the case of pearl oysters.

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

Fishes
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

, 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 ...
