Аннотация: The circadian rhythm of grazing of microalgae by a laboratory culture of Ceriodaphnia quadrangula under continuous illumination was studied by continuous registration of chlorophyll fluorescence at the outlet of a flow-through cultivator. A culture of green alga Chlorella vulgaris was used as a feed. The data obtained were treated by the statistical spectral analysis. It was found that animals preliminarily grown under a 12 h light : 12 h dark regime and transferred to constant light showed two maxima in the circadian rhythm of grazing with periods of 0.7 and 1.1 h. Animals preliminarily grown under constant light showed no circadian rhythm of grazing. It was concluded that the circadian rhythm of grazing of C. quadrangula has endogenous nature and can change according to light conditions.
