| Research Abstract |
Green microalgae such as Nannochloropsis oculata are widely used for fish seedlings in aquaculture industry as Green Water. In this study, the abundance of Roseobacter clade is being focused, as some strains are known to produce inhibitory substances against fish pathogenic bacteria. In N. oculata culture, Roseobacter clade (RCA) were various and came to be abundant. Interestingly, the combination of Roseobacter clade and phytoplankton reinforced the killing effect of RCA against some V. anguillarum.
