Research Article: Proximate composition and amino acid profile of the whole body of juvenile Persian sturgeon (Acipenser persicus)

The main objective of the current study was to analyze the proximate composition and the amino acid profile of the Persian sturgeon (Acipenser persicus).Forty-eight fish (with an initial weight of 96.60± 7.45 g) were randomly sampled from a local sturgeon farm in Mazandaran, Iran.The proximate analysis of the fish body showed 24.38 ± 1.62 g/100g ww of dry matter, 61.52 ± 1.65 g/100g dw of crude protein, 10.53 ± 0.18 g/100g dw of lipid, 16.48 ± 1.3 g/100g dw of ash, 0.94 ± 0.03 % of NH3, and 2.45 ± 0.18 % of phosphorus.The essential and non essential amino acid composition provided the following values: Methionine: 1.57 ± 0.06 %, Threonine: 2.34 ± 0.08 %, Tryptophan: 0.56 ± 0.02 %, Arginine: 3.37 ± 0.12 %, Histidine: 1.32 ± 0.02 %, Isoleucine: 2.35 ± 0.05 %, Leucine: 4.27 ± 0.32 %, Lysine: 4.34 ± 0.27 %,
