    AnnotationIn this study, we aimed to set up and test two models of annular-column photobioreactors (AC-PBR 1 and AC-PBR 2) in order to produce microalgae for fish hatcheries. Both models with a different design were characterized by a short light-path and central LED light source providing homogenous illumination of thin culture layer, sufficient mixing, and continuous temperature control guaranteed a stable cultivation regime and high biomass productivity. The AC-PBR 1 is characterized by a culture thickness of 5.5 cm and the maximum irradiance of 1200 mu mol photons m(-2) s(-1) while in AC-PBR 2, the culture layer was decreased to 4.6 cm and the maximum irradiance intensity could reach 1600 mu mol photons m(-2) s(-1). AC-PBR 1 and AC-PBR 2 were compared using the selected microalgae strain Vischeria helvetica (class Eustigmatophyceae) which is a suitable feed source for rotifers further used as a live food for fish larvae. The photosynthetic performance, biomass productivity, pigment content, and fatty acid profile were evaluated. The volumetric productivity under continuous illumination at optimal growth temperature reached 0.16 and 0.33 g DW L-1 day(-1), corresponding to an areal productivity of 12.4 and 18.9 g DW m(-2) day(-1) for AC-PBR 1 and AC-BR2, respectively.
