Rotifer production in a shallow artificial lake (Lobo-Broa Reservoir) was studied for twenty consecutive days between August 25, 1995 and September 13, 1995, during the dry season. Two species were dominant, during this period namely Filinia pejleri and Keratella americana, contributing, respectively, 36% and 28% to total rotifer numbers. Production estimates of these species were, respectively, 41.93 and 80.70 micrograms dry weight.m-3.d-1, corresponding to 18.45 and 35.51 micrograms Cm-3.d-1. The population of F. pejleri was numerically more abundant than that of K. americana, while the production of the former was less, as a result of lower egg to female ratios.
1995年旱季期间，于8月25日至9月13日连续20天对一个浅人工湖（洛博-布罗阿水库）中的轮虫产量进行了研究。在此期间，有两个优势物种，即佩氏叶轮虫和美洲龟甲轮虫，分别占轮虫总数的36%和28%。这两个物种的产量估计分别为41.93和80.70微克干重·立方米⁻³·天⁻¹，分别相当于18.45和35.51微克碳·立方米⁻³·天⁻¹。佩氏叶轮虫的种群数量在数值上比美洲龟甲轮虫更多，而前者的产量较低，这是由于其卵雌比更低。
