Description The black-lip pearl oyster, Pinctada margaritifera is widely distributed in Indo-Pacific region
and has prime importance in the production of black pearls. In India, its natural occurrence is
confined to the Andaman and Nicobar Islands. The biometric relationships between (dorso-ventral
measurement [DVM] and Hinge Length [HL]; Thickness [THK] and Total Weight [TWT]) were
studied from 458 oysters collected from these islands which were grouped in to 5 length classes.
In all size groups, there was increase in weight with increase in length. The highest coefficient
(r2=0.7828) was obtained for the animals with DVM ranging from 76 to 95 mm. The correlation
coefficient ‘r’ was low for DVM-HL and slightly higher for DVM-THK. Comparisons of biometric
relationships of the natural populations of the Indian pearl oysters with that of farmed oysters in
other regions indicated xenomorphism in pearl oysters in Andaman and Nicobar Islands due to
restricted space in natural habitats.
