Abstract: The present study focused on the effect of water temperature on growth and feed conversion ratio of juvenile Black Sea flounder (Platichthys flesus luscus; initial weight: 2.0 g ± 0.01 g). The experiment was carried out for 84 days with the following range of water temperatures: 13, 17, 21, and 25 °C. Growth, food consumption, and feed conversion ratio were the highest at 21 °C and the lowest at 13 °C. The growth rate of the fish increased with water temperatures up to 21 °C and it decreased significantly with a further increase in temperature. The conclusion of this study was that the optimal water temperatures for growth and feed conversion ratio for Black Sea flounder were 20.9 °C and 20.2 °C, respectively.
