All pearls entering Bahrain are examined by the Gemstone and Pearl Testing Laboratory, which was established by the Ministry of Commerce in 1990.About 4,000 to 5,000 pearls of good quality were fished each season during the boom years between 1850 and 1930. The pearl fisheries returned to the control of the local sheikhs who generously allowed their subjects to fish for pearls for a small fee. The city of Masqat (Muscat) in the Gulf of Oman was the main trade center. The left valve is deeper than the right. The emergence of new diseases in association with decreased pearl oyster production and reduced pearl quality should be anticipated by farm managers, fisheries biologists and molluscan pathologists.
Clearly, broodstock should be selected on the basis of desirable qualities in the offspring. The majority of pearls are small and irregular in shape, mainly 4–6 mm in size. BMC Evolutionary Biology 10: 342.

Currently, pearls from the Gulf are sold to Indian pearl dealers who clean, bleach and drill them in India, from where they are sold internationally and are also sold back the Gulf states.New pearls from present fisheries account for only 15% of the trade and are still called “Basra pearls”. There are even yellowish-pink pearls that resemble the apricot hue of today’s Chinese freshwater cultured pearls. The majority of pearls are small and irregular in shape, mainly 4–6 mm in size. After 1515, when Alfonso d’Albuquerque came to the Strait of Hormuz, the Portuguese brought the pearl fisheries under their control. The emergence of new diseases in association with decreased pearl oyster production and reduced pearl quality should be anticipated by farm managers, fisheries biologists and molluscan pathologists.

Pinctada fucata. All pearls entering Bahrain are examined by the Gemstone and Pearl Testing Laboratory, which was established by the Ministry of Commerce in 1990.About 4,000 to 5,000 pearls of good quality were fished each season during the boom years between 1850 and 1930. For those who utilize … For the purposes of this chapter, disease is taken to include abnormalities of structure or function and includes sub-clinical disease in which there may be no tangible signs of disease, but which is manifest by physico-chemical abnormalities including retarded growth and production. of … The pearl fisheries returned to the control of the local sheikhs who generously allowed their subjects to fish for pearls for a small fee. Other names used for the shells from the Gulf were “Bastard Shell” and “Lapi Shell”.The pearl oysters were opened on deck with a knife; large pearls were removed immediately by hand and the rest were harvested using 25 brass sieves, the so-called “tasah”.
It was reported that Pinctada fucata mantle gene 3 (PFMG3) with an N-terminal signal peptide could be secreted into the nacre of P. fucata.

However, the underlying mechanisms have not been studied. They develop first as males and retain this condition for one or several reproductive cycles until changing sex.

Colors range from white to dark cream and very light pink.
