Fermented sweet potato residue, Growth performance, Immune organ morphology, Antioxidant capacity, Nonspecific immunity, Aquaculture. Fisheries. Angling, SH1-691

The aim of this study was to investigate the effects of fermented sweet potato residue (FSP) on growth performance, immune organ morphology, antioxidant capacity and nonspecific immunity in common carp. One hundred and twenty healthy and disease-free common carp with an initial body weight of (408.36±26.12) g were randomly divided into four groups, FSP0, FSP10, FSP20 and FSP30, and their base diet was supplemented with 0, 10%, 20% and 30% FSP, respectively.There were with 10 common carp in each tank, and the experiment was replicated three times. The results showed that the weight gain rate and specific growth rate of the FSP10 and FSP20 groups were significantly greater (p
