In order to domesticate Litopenaeus vannamei as a soloution 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 postlarva reared from imported L. vannamei were cultured. After culture season the adult shrimps were transported to green house ponds for wintering. It is then relocated to hatchery saloon. After eye stalk ablation and maturation the female brood stocks were intrduced to matured male for copulation at ponds. During the study period , male and female shrimps attained ful maturation at end _ april by temperature over 25 ºC, the copulation process was started significantly. Finally of the 12 instanses of copulation, one insance resulted nauplii production . The best maturationwas observed at 28 1 ± o c 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.
