¹Final body weight (FBW, g) = final body weight/final number of fish; ²Weight gain rate (WGR, %) = 100 × (final body weight−initial body weight)/initial body weight; ³Specific growth rate (SGR, % day⁻¹) = 100 × (Ln final individual weight−Ln initial individual weight)/number of feeding days; ⁴Feed conversion ratio (FCR) = feed consumed/weight gain; ⁵Survival rate (SR, %) = 100 × (final number of fish)/(initial number of fish); ⁶Condition factor (CF, g/cm ³) = 100 × body weight/body length³; ⁷Hepatosomatic index (HSI, %) = 100 × hepatosomatic wet weight/body wet weight; ⁸Viscerosomatic index (VSI, %) = 100 × (viscera weight, g)/(whole bodyweight, g); ^1–5Values are means ± SEM (n = 3); ^6–8Values are means ± SEM (n = 9). One-way ANOVA followed by Duncan’s test was used to analyze the discrepancy among all the groups. Values in the same row with different superscripts represent statistically significant difference (). The P-values indicate a significantly linear or quadratic dose–response relationship (). Liner trend and quadratic trend were analyzed by polynomial contrasts (A, ANOVA; L, linear; Q, quadratic). EGCG was supplemented at 0, 0.05, 0.25, 0.5, or 1 g/kg.
