Aquaculture is important business some fish farms use underground water that may has high salinity. The aim of this study is to evaluate the effect of eight different types of diets on enhancing the growth rate of the rotifer, Brachionus plicatilis lives in 40 ppt saline water in 2020. The diets used in the study are T1 (Nannochloropsis oculata), T2 (Tetraselmis suecica), T3 (N. oculata + T. suecica), T4 (N. oculata + yeast; Saccharomyces cerevisiae), T5 (T. suecica + yeast), T6 (S. parkle), T7 (S. Parkle + yeast) and T8 (yeast). The results revealed that the rotifer fed for S. parkle showed the highest growth population (818 Indv. /mL) with a highly significant difference (p < 0.05). On the other hand, rotifers fed the yeast (S. cerevisiae) showed the lowest population growth (355 Indv. /mL). The outcome of the current study indicates that S. parkle commercial diet is very appropriate for the stock culture of B. plicatilis due to its ability to increase the growth rate of the rotifer in a short time under the current conditions. S. Parkle feeding led to an increase in the densities of rotifers in high salinities.
