Preliminary survey of length correlation in Pinctada fucata pearl oyster and evaluation of its muscle
61 specimens of pearl oyster (Pinctada fucata) were collected from Bandar-e-Nakhyloo in Hormozgan Province and were subjected to biometrical measurements. The measurements carried out included dorsoventrally and anterior posterior measurements along with hinge length, thickness, muscle weight, oyster weight without shell, total body mass excluding gill, and total body mass. The maximum correlation coefficient (r=0.69) was observed between total oyster weight and its weight without shell. In contrast, the least correlation coefficient (r=0.04) was found between thickness and muscle weight. It was revealed that the correlation between total oyster weight and hinge length follows a curvilinear pattern (r=0.34). Additionally correlation between dorsoventrally measurement and total oyster weight showed a similar pattern (r=0.52). An estimate of available oyster muscle for conserving is given in the paper. Also, frequency, body weight without shell, muscle weight, dorsoventrally measurements, total body mass including gill, total oyster weight, and finally correlation between dorsoventrally measurements and total weight are shown in diagrams.
