Abstract :The effects of 4 different experimental photoperiod regimes, LDN insert ignore into journalissuearticles values(natural photoperiod);, LD24:0 insert ignore into journalissuearticles values(24 h light:0 h dark);, LD12:12 insert ignore into journalissuearticles values(12 h light:12 h dark); and LD0:24 insert ignore into journalissuearticles values(0 h light:24 h dark);, on feed intake and growth parameters of juvenile turbot insert ignore into journalissuearticles values(21 ± 2.3 g); in the Black Sea were determined. Growth was highest in the group exposed to the continuous photoperiod insert ignore into journalissuearticles values(LD24:0);, followed by the LD12:12, LDN and LD0:24 groups in descending order. The lowest growth rate was recorded in the LD0:24 group. According to the results obtained, LD24:0 and LD12:12 photoperiod exposures are best for better growth and food conversion in juvenile turbot.
