This study aims to determine the best dose of bakers yeast in culture Brachionus plicatilis. The research was conducted in July-September 2015 in the Mandiri Laboratory of BTN Puri Meninting West Lombok District. This experiment  uses a completely randomized design ( CRD ), which consists of 6 treatments and repeated 3 times , in order to obtain 18 units of trial that treatment A : without feed , treatment B : feed Nannochloropsis spp., treatment C : 7.5 mg/L, treatment D : 15.0 mg/L , treatment E : 22.5 mg/L , and treatment F : 30.0 mg/L. The results showed that the difference in the level of baker's yeast significantly affect the population growth of Brachionus plicatilis, which obtained the highest population density in the yeast dose of 30.0 mg/L of 90 individuals/m
