Shrimp culture is one of the important fields in aquaculture which supply a part of necessary animal protein needed by the human being. Due to the limited catch of shrimp from the sea, its culture increasingly was considered. Shrimp culture industry was spreading quickly in developed and developing countries. The aim of this study was determine the bionormative parameters of vannamei shrimp culture using Caspian Sea brakish water in Mazandaran province, comparing the growth parameters of vannamei (Litopenaeus vannamei) shrimp culture with Caspian Sea brackish water and saline water of Persian Gulf and also possibility of introduction a new aquatic spciese for rereaing in Mazandaran province. The Shrimp Litopenaeus vannamei reared with the brackish water (10±0.43ppt) of the Caspian Sea in Mazandaran province and the Caspian Sea Ecological Research Iinstitute in summer 1391. In this study, post larvae-12 was prepared from Boshehr province. Initially, post larvae in brackish water were gradually adopted. The density of 35 per square pieces in an earthen pond (1000m2) was stocking.The rearing time was 85 days. Average daily growths: 0.31±0.037g; final mean weight: 21.11±0.71; Feed conversion ratio: 0.79 and final yield: 531kg were determined. In addition the experiment of 2012, the results of Mazandaran province vannamei shrimp culture, were observed in 2014 and 2015, the average weight average daily growing and FCR % were 20-18 g and 0.68 - 0.77 respectively during 90 days culture period with harvesting of 40 PL /m2 at cement culture pond. In 2014, average weight, average daily growing and FCR % were 22.6 g and 0.7, respectively during 60 days culture period with harvesting of 18 PL /m2 at earthen pond in Mazandaran province. Then the results of this study, wwere compared with scientific- research reports in field of vannamei shrimp culture from institute and fisheries research centers of south (Bushehr province) and north (Golestan province) of Iran. Important shrimp culture parameters were used in this comparing specially, growth parameters (average weight, average daily growing and survival rate), FCR, final crop, production per hectare and the best harvesting. Therefore, based on initial hypothesis and acquired results, was observred that, vannamie shrimp was reared well using Caspian Sea brakish water in Mazandaran province. In addition, it seems that, vannamei shrimp was gained better results in Mazandaran province compared to two other provinces, because of suitable climate conditions specially water salinity.Pages
