The results show that Ceratium provides a suitable food source for advanced copepodite instars and adult cyclopoid copepods, although it is not a The seasonal abundance of the dominant dinoflagellate, Ceratium fusus, was investigated from January 2000 to December 2003 in a coastal region of Sagami Bay, Japan. The growth of this species was also examined under laboratory conditions. 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. Most possess chloroplasts containing chlorophyll and a yellow-brown accessory pigment, but some are heterotrophic. Dinoflagellates have a cellulose cell wall that consists of overlapping armored labeled prey with presumably unaltered surface char- acteristics.
The dinoflagellate genus Ceratium is found all over the world in limnic and marine kept cool in labeled buckets until investigation at Arctic Station, where after

They contain a pellicle, which is a shell, that is made from the cell membrane and vesicles; vesicles are composed of cross-linked cellulose, forming the plates. The pellicle divides into two structures known as the epicone and hypocone that lie above and below the transverse Armored dinoflagellates have two major plate regions composed of two to 100 individual plates. The edges of the plates overlap, sliding apart as the cell increases in size and allowing the cell to expand. The plates come in many varied shapes, from spherical forms like Peridinium to elongate horn-like forms such as Ceratium. Ceratium furca.

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

Ceratium species belong to the group of dinoflagellates known as dinophysiales, meaning they contain armored plates. They contain a pellicle, which is a shell, that is made from the cell membrane and vesicles; vesicles are composed of cross-linked cellulose, forming the plates.
