    Description: Pharaoh Cuttlefish (Sepia pharaonis) is commercially important and native cephalopods in the Persian Gulf and Oman Sea. In 2013, a total of 150 eggs of Pharaoh Cuttlefish were collected from 20 m depth in about 6 miles south of Lengeh Port and transferred to the laboratory of Mollusks Research Station in Bandar-e Lengeh. Eggs were incubated in temperature of 27.5±0.5 0C (mean ± SD) and salinity of about 37-38 ppt. After about 15±3 days (mean ± SD), eggs were hatched and the mean (±SD) of mantle length and wet weight of new hatched juveniles were 6.1±0.3 mm and 0.15±.04 g, respectively. In the first month, Artemia, Mysid and PL of L. vannamei shrimps were fed to juveniles and in second month it shifted to fish slices. After 30 days, average (±SD) mantle length and wet weight reached to 18.6±0.6 mm and 1.67±0.14 g, respectively. At the age of 60 days they reached to average (±SD) length of 32.3±4.2 mm and average (±SD) weight of 8.00±3.72 g. At the age of 120 days they reached to average (±SD) length of 74.5±11.3 mm and average (±SD) weight of 55.74±13.81 g. The sex was identified on the day of 150, and mate selecting occurred on 180th day, mating and spawning were occurred in days 208 and 210 of rearing period, respectively. Each female laid average (±SD) 185±30 eggs; and average (±SD) life spans for female and male were 212±7 and 218±20 days, respectively. Males were bigger than females and the biggest male reached to 157.9 mm in length and 367.10 g in weight. The biggest female reached to 105.1 mm in length and 227.18 g in weight. Results showed that Pharaoh Cuttlefish could easily be cultured under laboratory condition with possibility of rearing to the next generation after spawning.

    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.
