Abstract Incorporating macroalgae like Ulva species into integrated multi-trophic aquaculture (IMTA) enhances sustainability by filtering effluents and provide epiphytic bacteria, that can contribute to disease prevention. Colonizing ohnoi with Phaeobacter sp. 4UAC3 is promising for control in IMTA systems, but high light intensity impacts ’s persistence on . This study investigated the effect of different intensities regimes ability 4UAC3·to colonize U. Experiments assessed algal growth, water physicochemistry, microbial profiles using culture techniques 16S rRNA gene sequencing.
