其他摘要：ABSTRACT Moina macrocopa culture density can be improved by optimizing the fecundity, and somatic growth through the regulation of quality and quantity of feed. The purpose of this study were to determined how to use effectively the rice bran and cassava bran Manihot utilisima suspension on Moina, based on population, neonates production, adult percentage, biomass, metabolisme and nutritional state. In this study, Moina were cultured for eighth days using four concentrations of rice bran suspension and three concentrations of cassava suspension. This research found that M. macrocopa culture with rice bran suspension has higher population, neonates production, adult percentage and biomass than its culture with cassava bran suspension (P<0.05). This study also found that Moina culture with rice bran suspension has higher total value of RNA, total value of DNA, the ratio RNA/ DNA, FCR, and concentration of protein and amino acid than Moina culture with cassava bran suspension. Treatment D with the initial rice bran suspension concentration was 0.3 mL/L and was increased starting the second day and the end concentration on the eighth day was 1.2 mL/L has highest peak population of Moina 17,975 ind/L in seventh day, weight wet biomass 439 mg/L in eighth day and lower FCR 0.94.
