From: Variability of key-performance-indicators in commercial gilthead seabream hatcheries

Mean (± SD), min and max values of the basic abiotic conditions applied during the embryonic period and larval rearing of gilthead seabream in 4 European hatcheries. (A) Water temperature (°C). (B) Oxygen concentration (mg/L). (C) pH. D. Daily water exchange rate (% of tank volume). (E) Salinity (ppt). (F) Photoperiod (duration of light, hours). (G) Light intensity on the water surface (Lux). dph, days post hatching.
