Pearl aquaculture production is one of the most valuable industry in the world. Black lip pearl oyster Pinctada
margaritifera is one of the most important commercial species in the world that it is used for breeding and
production of pearl. To determine the basic requirements for black lip oyster growth and development of gonad
under controlled conditions, Pearl oysters with a total length of 80 mm shells that were in stage 2 maturation of
the island Hendorabi collected by diving operations and were transferred to Bandar Lengeh Research Station
Persian Gulf mollusks. Pearl oysters with length of 95 mm shells, was passed were all male. 25 percent of them
with a total length of 100-110 mm and all with a total length top of 110 mm were female. Then thay were fed for
45 days in appropriate conditions of temperature and photoperiod with March until late spring. Ggreatest
physical growth related to Diet with micro-algae Isochrysis sp (T.ISO), Cheatoceros calcitrans, Cheatoceros
mullerii, Pavlova lutheri and Tetraselmis suecica, which with the other treatments were significantly different
(p〈0.05). Most gonadal growth of the group 4 (Isochrysis sp (T.ISO), Pavlova lutheri, Cheatoceros calcitrans,
Cheatoceros mullerii ) was 70% in the treated females were spawning. Minimum total length of black lip oyster
in habitat of 80 mm, which were collected from a depth of 2 meters. There is no relationship between total length
Oysters and depth of 4 to 10 meters depth and minimum total length was 115 mm. The most density of Black lip
oyster were observed in the depths of 4 to 7 meters in the northwestern part of the island Hendorabi. There were
stronger correlation between biometric data, length-weight relative to length- length.
