Prey ciliates so labeled were ingested by larger ciliates and could be detected using fluores- cence microscopy. In the present study, we modified this method for use in the field to determine food vacuole contents and feeding rates of Ceratium Eurca, Ceratium furca is a primarily photosynthetic dinoflagellate also capable of ingesting other protists.

Physical and biochemical parameters for cells in 'semi-continuous' cultures. Average values were determined for each parameter once steady state had been reached (Days 19 to 30). There is a broad range of cell size: small cells (the aptly named Peridinium inconspicuum) may be 10 μm wide by 12 μm long, and large Ceratium may reach 400 μm in length.

During 1995 and 1996, we documented the abundance of C. furca in Chesapeake Bay and determined grazing rates on prey labeled with fluorescent microspheres.

Because of the difference in density, bodies of water will often stay as distinct layers and not mix. ABSTRACT. Ceratium furca is a primarily photosynthetic dinoflagellate also capable of ingesting other protists. During 1995 and 1996, we documented the abundance of C. furca in Chesapeake Bay and determined grazing rates on prey labeled with fluorescent microspheres. Abundance usually remained below 20 cells ml −1, although the species was capable of localized late‐summer blooms (≤ 478 2011-12-01 We studied the phagotrophic ability of dinoflagellate strain Karenia mikimotoi KM-Lü (isolated from the South China Sea), using fluorescent microspheres, bacteria isolated from the culture of K. mikimotoi and a marine microalgae Isochrysis galbana. We found that K. mikimotoi cultured under conditions of high light intensity could ingest fluorescent microspheres (diameters 0.5 and 2.0 μm) and The genus Ceratium is restricted to a small number of freshwater dinoflagellate species. Previously the genus contained also a large number of marine dinoflagellate species.

Microspheres added to natural plankton assemblages at a concentration of 5 x 10 6 to 10 7 ml-1 were rapidly ingested by a variety of planktonic organisms including small flagellates, ciliates, dinoflagellates, ebriids and amoebae. Ceratium fusus forms extensive blooms forming red tides in Eastern Asia regions (China, Philippines and Thailand; Baek et al. 2007). Habitat Ceratium fusus is mainly a coastal species, but it can be found in estuarine and oceanic environments (Montagnes 2006, Horner 2002).

In Sagami Bay, C. fusus increased significantly from April to September, and decreased from November to February, though it was found at all times through PHYLUM DINOFLAGELLATES – Ceratium characteristics: single-celled plankton that are important primary producers in freshwater and marine environments.

Sometimes the cells are attached to each other in pairs.The surface of the cell is broken by grooves that contain two mobile outgrowths (flagellae).

Most are labeled with a Latin binomial scientific name in ink, by Schweinitz. Three are labeled Nobis [ours], denoting new species that were described in the Conspectus: Peziza rhizophora, Poria cornuta (as Ceratium porioides), and Mesenteriaca grisea. Other than Perceval’s inscription, the volume is unsigned.
