Abstract: Nigella sativa oil has been used to determine whether it can improve the immunity of Penaeus vannamei Shrimps. In this study, Nigella sativa oil was used to coat commercial feed and fed to the Penaeus vannamei, where they were observed and data was collected for their growth and survival rate. Twenty shrimps were placed in different tanks and each tank was fed with their assigned type of feed and feeding rate percentage. There were a total of six tanks, two Control tanks, two Treatment 1 tanks and two Treatment 2 tanks. Shrimps in the Control tanks were fed with commercial feed, those in Treatment 1 tanks were fed with 10 mL/kg of Nigella sativa coated commercial feed and those in Treatment 2 tanks were fed with 20 mL/kg of Nigella sativa coated commercial feed. Before the project, it was hypothesized that the tanks fed with Treatment 2 would have the highest growth and survival rate. At the end of the project, Treatment 2 had the best survival and growth rates compared to Treatment 1 and Control. The results supported the hypothesis that the shrimps fed with more Nigella sativa oil had the highest growth rate and survival rate. However, it was also observed that Control had a higher growth rate compared to Treatment 1.
