Effect of different rearing systems on survival rate of hatchery reared Black Sea turbot, Scophthalmus maximus

Rearing experiments were carried out to examine the effect of different rearing systems on survival of hatchery reared Black Sea turbot, Scophthalmus maximus. The larvae were reared under natural light regime from hatching until 20 days old. Three groups were set as follows: Group I: continuously exchanged sea water (open-system), group II: stagnant seawater treated with 10 ppm EDTA, group III: stagnant seawater. The feeding regime consisted of Nannochloropsis, Brachionus and Artemia. From initial total length of 3.44±0.07 mm on day 0, larvae grew to 8.30±0.39 (group I), 8.45±0.56 (group II) and 8.51±0.50 mm (group III) on day 20. Survival rates were 21.1, 15.3 and 9.1% in group I, II, III, respectively.
