While most experiments investigating zooplankton grazing on harmful cyanobacteria have been carried out with metazoan plankton, several protozoa can also feed efficiently on cyanobacteria. We investigated grazing by the mixotrophic flagellate Ochromonas sp. on the toxic cyanobacterium Microcystis aeruginosa. Ochromonas sp. grew rapidly on M. aeruginosa and had a strong impact on the population density of its prey. However, specific growth rates of Ochromonas sp. decreased over time, possibly… CONTINUE READING
