P ≤ 0.001, indicates significant differences between the V. anguillarum concentration at 4 and 9 dpf. Letters indicate differences between treated and not inoculated larvae at the respective day, ANOVA with Dunnet multiple comparison corrected test.
ni, larvae not inoculated with yeasts.
−, Not determined.
