FIG. 1.
Diagrammatic representation of a typical production management model of gilthead sea bream and European sea bass from hatch to the end of the preongrowing stage, based on H-2 facilities. In study B, sampling points (arrows) were selected according to changes in food type, water quality, and location. Fine filtration, 30- to 40-μm-pore-size sand filter, plus 10- and 20-μm-pore-size sequential cartridge filters. Coarse filtration, 30- to 40-μm-pore-size sand filter only. UV irradiation was performed with 61.3 to 52.1 mJ/cm2 and a water flow of 25 to 30 m3/h (DeltaC30; Aquabona, S. L.).
