PPV = protein production value; LPV = lipid production value; APV = ash production value.

^{a, b, c} Different superscript letterswithin a row indicate significant differences (P < 0.05).

¹HFD+GA 0.5, HFD diet supplemented with 0.5 mg/kg GA; HFD+GA 1.0, HFD diet supplemented with 1.0 mg/kg GA; HFD+GA 1.5, HFD diet supplemented with 1.5 mg/kg GA. Values are mean ± SE of three replicate groups, with 6 fish per tank.

²Protein production value (%) = 100 × body protein gain weight/protein intake.

³Lipid production value (%) = 100 × body fat gain weigh/fat intake.

⁴Ash production value (%) = 100 × body ash gain weight/ash intake.
