CNT2, control; CNT2-I, control with fish infected with A.hydrophila and fed the control diet without any additive; CNT2-I-A, control with fish infected with A. hydrophila and fed the control diet supplemented with the antibiotic oxytetracycline (1 g/199 g DM), while MFE-2-I, MFE-5-I, and MFE-7-I were control diet plus 2, 5, or 7 g/kg Morus alba foliage extract, respectively, and fish infected with A. hydrophila.
