Box-plot graph of goblet cell density in the anterior-mid intestine of gilthead seabream (Sparus aurata) fed experimental low fishmeal diets containing Debaryomyces hansenii (1.1%, 17.2 × 105 CFU; Yeast diet) or devoid of the probiotic (Control diet). No statistically significant differences were detected among dietary treatments (Student’s t-test; P > 0.05). Mean line within the boxplot indicate the average value of the series; O and ◻ = outlier points of the series
