Moina siamensis is one of the most successful Cladocerans used for mass culture as live feed for the larvae of crustaceans and different fish. Moina is fed Chlorella; however, there is a risk of predation by larger zooplanktons, which appear in the tanks where the Chlorella are grown. As a solution, specialized commercial feeds have been produced. The main objective of this study was to explore an alternative to Chlorella for Moina culture. The present trial was conducted to compare the performance of Chlorella, yeast, and a commercial diet on the biography, population growth, and density. Seven adult Moina as replicates per treatment were placed in each plastic cup individually and monitored. They were fed three types of feed at a concentration of 6×106 mL-1. The experiment continued until all the adult Moina died. The result showed that the average day of maturation, the number of newborns per day, the number of newborns per crop, and the number of crops from different diets were similar. The Moina fed Chlorella sp. showed the longest life span (9.00±0.8 days), and the shortest with the commercial feed (5.6±0.3 days). However, commercial feed and the Chlorella did not differ in terms of the final population of Moina, but they produced more than when fed the yeast. Therefore, the results demonstrated that the commercial feed was similar to that of Chlorella and can serve as an alternative diet.
