The effect of giving fermented rice bran suspension on fecundity and production of moina macrocopa offspring per parent

Abstract

The objectives of this research were: 1) determine the effect of fermented rice bran suspension concentration on the fecundity and production of M. macrocopa offspring per parent, 2) determine the optimal concentration of fermented rice bran suspension on the fecundity and production of M. macrocopa offspring per parent. This research used an experimental method with a completely randomized design consisting of six treatments of suspension of rice bran without fermentation (P0), 19.54 mg/L fermented rice bran suspension (P1), 21.98 mg/L fermented rice bran suspension (P2), 24.42 mg/L fermented rice bran suspension (P3), 26.68 mg/L fermented rice bran suspension (P4) and 29.30 mg/L fermented rice bran suspension (P5) in four replications for each. The results of the culture with a different concentration of rice bran suspension showed a significant difference (P <0.05) on the fecundity and production of M. macrocopa offspring per parent. The highest fecundity and production of M. macrocopa offspring per parent occurred in M. macrocopa culture with a concentration of fermented rice bran suspension of 29.30 mg/L (P5) with the fecundity 21-25 grains/parent and production of offspring 20-24 ind/parent.
