For this purpose, 120 fingerlings of tiger oscar, with a mean weight of 7.5±0.5g, were fed with experimental diets for 8 weeks. At the end of this period, fish were sampled to measure the parameters. The results of data analysis statistically showed that there was a significant difference between the treatment fed with astaxanthin and other treatments in WG, FCR, SGR, BWI, length increase and lysozyme activity (P<0.05). However, there was no significant difference between treatments in other immunological parameters (total immunoglobulin, IgM), hematological parameters and total carotenoids (P>0.05). The results of this study showed that the pigments used can improve the growth, immunity and coloration factors of the tiger oscar. Among these pigments, astaxanthin has a better performance than other pigments.
