Description:
As pearling has been banned in Iran since 2006, stocks of pearl oysters has not been
investigated during these years; therefore, condition of natural habitats for Pinctada radiata
in its old habitats was surveyed in present research. Shallow waters around Hendorabi Island
were searched with diving and two habitats namely “Sooleh” and “Sahel-e-sheni”, were
considered for study. The pearl oysters had most distribution in these habitats in depth ranges
of 7 to 12 m and 8 to 11 m, respectively. Total stock in Sooleh and Sahel-e-sheni was
surveyed near 35700 and 12563 Pinctada radiata, respectively, of which 22% and 67% were
catchable, respectively. Catch Per Unit of Area (CPUA) in Sooleh and Sahel-e-sheni habitats
was estimated equal to 0.3 N/m2 in both habitats, and Catch Per Unit of Effort (CPUE) in
these habitats was calculated equal to 59.5 N/hr and 50.3 N/hr, respectively. Results of this
study demonstrated that area, stocks and CPUA for studied habitats were less than previous
years. Despite of interdict of pearling in this region since 7 years ago, stock revival has done slowly.
