Disease resistance of pacu Piaractus mesopotamicus (Holmberg, 1887) fed with β-glucan [PDF]
Brazilian Journal of Biology, 2014 Effects of β-glucan on innate immune responses and survival were studied in pacu experimentally infected with Aeromonas hydrophila. Fish fed diets containing 0, 0.1% and 1% β-glucan were injected with A. hydrophila. β-glucan enhanced fish survival in both treated groups (26.7% and 21.2% of the control, respectively).

Animal Research and One Health, Volume 3, Issue 1, Page 54-70, February 2025.Aeromonas hydrophila infection is one of the major issues limiting freshwater fish production, and antibiotics play important roles in the control of diseases. In‐feed florfenicol administration at 15 mg/kg fish biomass/day for 10 days effectively reduced bacteria‐induced mortalities and physiological stress.
