| Abstract | ||
| Moina sp. were cultured with varying concentrations of feeding rations to find the optimal feed turbidity for population growth. Baker’s yeast (Saccharomyces cerevisiae) was added to the culture tanks until the water reached the desired feed turbidities (20, 25, 30, 35, and 40cm) corresponding to five treatment levels; each treatment was performed in triplicate. The results show that feed turbidity does affect the growth and population density of Moina sp. At turbidities of 20–25cm, the density reached a maximum of 860 individuals (ind.)/L on day 4; at 30cm, the maximum density was 1,017 ind./L on day 6; and at turbidities of 35–40cm, the maximum population density was over 1,300 ind./L on day 9 of the experiment. The findings reveal that the highest Moina biomass was attained with the tubidity from 35-40cm. | ||
