The mean meat yield of 67.59%±0.48 in wild trout was significantly higher than that of 64.46%±0.73 in cultured trout (P<0.05). The mean crude protein, crude lipid, moisture contents and crude ash were 17.36% ± 0.037-16.66% ± 0.37, 2.71% ± 0.21-3.62%±0.224, 78.10% ± 0.239-77.43% ± 0.387, 1.16% ± 0.03-1.21% ± 0.029 in wild and cultured trout, respectively. The mean crude lipid in cultured trout was significantly higher from the wild trout (P<0.05). The mean protein amount is similar for both fish groups. Mean carbohydrate content in the wild trout was found to be 0.54±0.12 (g/100 g) and cultured trout carbohydrate was found to be 0.57±0.12 (g/100 g) (P<0.05). Maximum value at Total amino acid (TAA) was reach on cultured fish at Jun (17880 mg/100 g), wild trout was reach (18755 mg/100 g) at April. Total essential amino acid (TEAA) value was demonstrate significant variation (P<0.05). Results showed that, cultivated and wild brown trout fillets are well-balanced food source in terms of E/NE ratios in all seasons.
