In order to domesticate Litopenaeus vannamei as a solution to single species shrimp aquaculture of Penaeus indicus and to reduce risk of shrimp culture in emergency cases, this study was carried out. Initially the postlarvae reared from imported L. vannamei were cultured. After culture season the adult shrimps were transported to greenhouse ponds for wintering. It is then relocated to hatchery saloon. After eye stalk ablation and maturation the female brood stocks were introduced to matured male for copulation at ponds. During the study period, male and female shrimp’s attained full maturation at end – April by temperature over 25ºC, the copulation process was started significantly. Finally of the 12 instances of copulation, one instance resulted nauplii production. The best maturation was observed at 28 ֯C ±1 and salinity30 to 33PPT and pH of 8 to 8.3 Fresh sea worms and squid showed the highest effect on fecundity in brood stocks. Besides, the spring season was obtained to be the best period for brood stock production in Bushehr province.
