Description: Compared to January fish, April fish showed a slight increase in genera Proteobacteria (15% and 10% in Reference fed and Test-fed fish, respectively) and Mycoplasma (4% and 29.5% in Reference fed and Test- fed fish, respectively)
Abundance in Group 1: increased abundance in Fishes fed with test diet in April
