抄録: We investigated the effects of fortifying a diet of Chlorella vulgaris with Selenium (Se) on sexual and asexual reproduction of rotifers in the Brachionus plicatilis species complex: i.e. two strains of B. plicatilis sensu stricto and one of Brachionus rotundiformis. These rotifers were cultured for 8–10 days on one of three different diets that were adjusted to provide the same dry weight of food: non-fortified Chlorella, Se-fortified Chlorella, and Nannochloropsis oculata. B. plicatilis (Makishima strain), which is obligatorily asexual, showed no difference in population growth rate among the three different diets (r = 0.55–0.61). On the other hand, B. plicatilis (NH17L strain), which reproduces by cyclical parthenogenesis, showed higher population growth (r = 0.25) and also higher rates of fertilization (35.9%) and absolute resting egg production (2803.9 eggs/g food) with the Se-fortified Chlorella diet than with other foods. Although B. rotundiformis (Kochi strain), which also exhibits cyclical parthenogenesis, showed no differences in population growth among the three different diets (r = 0.42–0.48), sexual reproduction parameters were different depending on the feeding regime. The highest mixis (26.2%), fertilization (72.6%), and resting egg production (3489.9 eggs/g food) were observed with the Se-fortified Chlorella diet. We posit that the effect of Se-fortified diet was greater on the resting egg production by enhancing male fertility than on population growth.
