Values are means from triplicate groups of juvenile olive flounder where the values in each row with different superscripts are significantly different (mean ± SEM; p < 0.05).
Tested by Elisa kit (CUSABIO, Houston, TX, USA).
GOT, glutamic oxaloacetic transaminase; GPT, glutamic pyruvate transaminase; TP, total protein; TG, triglyceride; TCHO, total cholesterol; GLU, glucose.
