Sumario: A study to technically and economically evaluate the addition of pure oxygen in a culture of rotifers for feeding marine fish in the Pacific Marine Park, Puntarenas, Costa Rica was performed. The results showed no significant differences (ANOVA P> 0.05) between the cultivation with addition of oxygen treatment and control, regarding the instantaneous growth rate, crop yield, doubling time, rotifers length and maximum densities reached. Concerning the economic analysis, control culture was 53% less expensive compared to the addition of oxygen system.
