Effect of the different diets on growth and nutritive parameters in rainbow trout.

	Experimental Diets
	FM0	FM10	FM20	p-Value
Initial weight (g)	13.60 ± 0.23	13.43 ± 0.23	13.13 ± 0.23	0.3911
Final weight (g)	49.07 ^b ± 1.69	72.94 ^a ± 1.69	72.24 ^a ± 1.69	0.0001
Survival (%)	51.11 ^b ± 5.62	81.67 ^a ± 5.62	93.33 ^a ± 5.62	0.0046
SGR ¹ (% day⁻¹).	1.73 ^b ± 0.04	2.24 ^a ± 0.04	2.21 ^a ± 0.04	0.0043
FI (g 100 g fish⁻¹ day⁻¹) ²	2.10 ^a ± 0.06	1.85 ^b ± 0.06	1.79 ^b ± 0.06	0.0188
FCR ³	1.52 ^b ± 0.06	1.09 ^a ± 0.06	1.01 ^a ± 0.06	0.0018
PER ⁴	1.62 ^b ± 0.09	2.31 ^a ± 0.09	2.49 ^a ± 0.09	0.0025

¹ SGR, Specific growth rate = 100 × ln (final weight/initial weight)/days. ² FI, feed intake = 100 × feed consumption (g)/average biomass (g) × days. ³ FCR, feed conversion ratio = feed consumption (g)/biomass gain (g). ⁴ PER, protein efficiency ratio = biomass gain (g)/protein intake (g). Means of triplicate groups. Values are presented as mean ± SEM (n = 3). Values in the same row with different superscript letters are significantly different (p < 0.05). Initial weight was considered as covariable for final weight and SGR.
