Abstract
Three micro algae, Ankistrodesmus convolutus, Scenedesmus incrassatulus and Chlorella vulgaris, at three concentrations, were tested as diets for Moina macrocopa. Their effect on reproduction, fecundity, growth and survival was evaluated. All three algae satisfied the nutritional requirements of M. macrocopa, despite their difference in size. The best concentration, expressed in dry weight, was 5 mg l−1 for all three. Time to first reproduction was 4 days with all diets. Average time between clutches was 33 hours, and maximum number of clutches was 12; the highest average number of offspring per brood was 27. The largest broods were the fourth to sixth, depending on the diet. Ephippium hatching depends on temperature, taking only 24 hours at 30 °C and 48 hours at 27 °C. This species could be an important test organism in aquatic bioassays, and a live food in aquaculture.
