| Outline of Final Research Achievements |
Green microalgae are widely used for fish seedlings in aquaculture industry as green water. The aim of this study was to evaluate the possible correlations between bacterial community structure of fish larva and the environmental compartments of their habitat. The gut microbiota of fish larvae was mainly influenced the microbiota of feed, however the good bacteria, Sulfitobacter sp., found in green water of Nannochloropsis oculata was also settled down in the gut of larvae of red sea bream. It was also found that diatom green water had its own good bacterial community, which suppressed the growth of bad bacteria.
