Grazing of the dinoflagellate Noctiluca scintillans on the paralytic toxin-producing dinoflagellate Gymnodinium catenatum: Does grazing eliminate cells during a bloom?

Temperature and nutrient concentrations were measured during a mixed bloom of Noctiluca scintillans and Gymnodinium catenatum in La Paz Bay, Gulf of California. Under laboratory conditions, we offered three concentrations of G. catenatum (312, 625, or 1015 cells mL–1) to 0.53 N. scintillans cells mL...

Under laboratory conditions, we offered three concentrations of G. catenatum (312, 625, or 1015 cells mL–1) to 0.53 N. scintillans cells mL–1 to study predation rates.

Ingestion rates varied; the highest ranged from 30 to 40 G. catenatum cells h–1 in each N. scintillans cell. A clear relation to the concentration of the diet was not evident. Low values of 1 to 3 G. catenatum cells h–1 in each N. scintillans cell were typical at the end of the trial.
