The growth performance, condition factor and organosomatic indices. For thermal growth coefficient, the mean of body weight from Jan-fish was set as initial body weight to calculate Apr-fish and Sep-fish. Black line and red dotted line indicate mean of Ref diet and Test diet in each sampling time points, respectively. Thermal growth coefficient (TGC) = [sampling body weight (g) ^1/3 - initial body weight (g) ^1/3] * (∑ day degree)⁻¹. Condition factor and organosomatic indices were calculated as: Condition Factor (CF) = 100* body weight (g) / body length³ (cm) and Intestinal somatic indices (OSI %) = 100* intestinal tissue weight / body weight (g). P < 0.05 (*); P < 0.01 (**); P < 0.001 (***); P < 0.0001 (****)
