Histological changes in the liver of black porgy Acanthopagrus schlegeli in the control (CS no ozone) and ozonated systems (T20: 20 g ozone/kg feed day−1 and T40: 40 g ozone/kg feed day−1) after 44 days of culture. a Control (CS). Note the hepatic cell (Hc), pancreas (P), and bile duct (Bd). b T20 group. AB-PAS section showing the free surface of alcian blue positive reaction in the bile duct and the swelling hepatic cells and degeneration of zymogen granules. c T20 group. The magnitude of hepatic cells and pancreas of figure b. d T40 group. Note the degeneration of hepatic cells and the abnormal pancreas
