a) inducing algae cell body production of an oil-producing algae by photoautotrophic growth;
b) initiating heterotrophic growth of the oil-producing algae using a stress induction mechanism;
c) inducing algal oil production by heterotrophic growth of the oil-producing algae, wherein the heterotrophic growth includes introducing a sugar feed to the oil-producing algae; and
