Different Concentration of Rice Bran Suspension on Fecundity and Offspring Production of Each Moina macrocopa Broodstock

Abstract

M. macrocopa culture success is influenced by the quality and quantity of inoculant, media, and feed used. Rice bran contains protein, lipid, amino acids, and vitamin B that supports M. macrocopa reproduction. This study aimed to determine the relationship of different rice bran suspension concentration against the reproduction of M. Macrocopa and the optimum concentration of bran suspension that produced the highest fecundity and offspring production level. This study was conducted using completely randomized design experimental method containing six treatments with four replications, i.e 22 mg/L (P0), 29.7 mg/L (P1), 39.6 mg/L (P2), 49.5 mg/L (P3), 59.4 mg/L (P4), and 69.3 mg/L (P5). Results showed that different suspension concentrations of rice bran in M. macrocopa influenced significantly (p < 0.05) against the fecundity and offspring production on each broodstock with the optimum rice bran suspension concentration of 69.3 mg/L, as it produced the highest fecundity and offspring production level of M. macrocopa.
