They generally swim to the surface of water in the morning for photosynthesis and then swim down again in late afternoon. Dinoflagellate members like Peridinium and Ceratium generally grow fast in summer and autumn and are quite able to swim actively to get the positions of favourable light and nutrients. The algae are positively phototactic and may form reddish-brown surface patches, called red tides. Nutrient requirements of dinoflagellate members are complex and may include organic substrate due to their heterotrophic nutrition.

Pinckney and Zingmark (1993) calculated the relative primary production of different types of algal community of wetlands and obtained as much as 22–38 % of epipelagic algae, 10–17 % for macroalgae and 30–59 % for vascular plants. The average C fixation rate of freshwater marsh phytoplanktons varied from 3 to 16 μ L−1 h−1 as estimated by different authors (Kotak and Robinson 1991; Mitsch and Reeder 1991). 9 g−2 year−1 (Stanley 1976). The importance of wetland phytoplanktons as a resource of food to herbivores depends on their availability throughout the year.
