The effects of nutrient loading and fish density on Ceratium hirundinella morphology were investigated during an experimental mesocosm study in Lake Créteil during the summer of 1990. In the presence of zooplanktivorous fish, more than 80 % of C. hirundinella cells had an hypotheca with two horns. In the enclosures without fish, we observed a highly significant increase in the proportion of C

Under even low magnifications of the microscope, the rich-brown cells with The horizontal distribution of Ceratium hirundinella (MULL.) BERGH was investigated in Lake Erken at ten stations in the summer of 1969. Abundance, total length and number of horns were studied. The conclusion is that the lake contained a horizontally uniform population of the alga. A correlation between form variation and the growth curve of the population was found, which can be explainable The effects of nutrient loading and fish density on Ceratium hirundinella morphology were investigated during an experimental mesocosm study in Lake Créteil during the summer of 1990.

Ceratium cells are photosynthetic but also contain vacuoles that suggest phagotrophy. Aplanospores (no flagella) are common, often after blooms. C. hirundinella has angular spores that are uninucleate, thick walled, and packed with glycogen as a storage reserve. As most spores they are resistant to dessication and remain viable for years.
