The quality and quantity of Moina ephippia is influenced by the male and female sexual ratios in the population. The availability of males in the population can increase the number of fertilized eggs and ephippia hatching rates. This study aims to examine the concentration of rice bran suspension in culture to produce the most male offspring, and the quality and quantity of ephippia produced. Moina was cultured for twelve days and from the fifth day the feed is given with different concentrations. The results of this study indicate that, Moina culture using bran suspension feed with a concentration of 0.36-0.48 ml/L starting on the fifth day resulted in the production of low calf offspring but produced the highest total production of male offspring of 818±35 ind/L. Increased production of male offspring increases the production of ephippia containing two eggs but does not increase the degree of hatching significantly.
