RÉSUMÉ

It has been shown that in the coastal waters of the Black Sea at the same temperature of water and illumination the light respiration of phytoplankton was closely similar to that registered in its open waters. The maximum values of light respiration (28–47% of the total production of phytoplankton) were registered in the samples with a predominance of Pyrrophyta and small forms of flagellate, whereas its minimum values (10–20%) – in the samples with a predominance of Bacillariophyta. At a high intensity of light, light respiration was 5 times higher than dark respiration, whereas at a low intensity of light it was 3 times higher than dark respiration. A decrease in the temperature of water by 10°C at the same illumination resulted in the decrease of light respiration by a factor of 2.4, and also in the decrease of dark respiration by a factor of 2.7. Regression relationship was established between the rate of light respiration and the biomass of Pyrrophyta and small forms of flagellate.
