Abstract

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 %, Valine: 2.71 ± 0.09 %, Phenylalanine: Correspondence M. Shamsaei, Department of Fisheries, Science and Research Branch, Islamic Azad University, P.O. Box: 14515-877, Tehran, Iran. (Email: m.shamsaie@srbiau.ac.ir) 2.22 ± 0.07 %, Glycine: 5.12 ± 0.17 %, Serine: 2.43 ± 0.05 %, Proline: 3.11 ± 0.06 %, Alanine: 3.85 ± 0.09 %, Cysteine: 0.53 ± 0.15 %, Asparagine: 5.08 ± 0.2 %, and Glutamine: 7.63 ± 0.16 % dry weight.

Overall, the Persian sturgeon is not only an invaluable source of protein (i.e., essential and non-essential amino acids), but it can also assist farmers and researchers in formulating fish diets based on their real nutrition needs.

研究论文:波斯鲟幼鱼(Acipenser persicus)全身近似组成和氨基酸谱

本研究的主要目的是分析波斯鲟(Acipenser persicus)的近似组成和氨基酸谱。从伊朗Mazandaran当地一家鲟鱼养殖场随机抽取48条鱼(初始体重为96.60±7.45 g)。鱼体的近似分析表明，干物质含量为24.38±1.62 g/100g ww，粗蛋白质含量为61.52±1.65 g/100g dw，脂肪含量为10.53±0.18 g/100g dw，灰分含量为16.48±1.3 g/100g dw, NH3含量为0.94±0.03%，磷含量为2.45±0.18%。必需和非必需氨基酸组成提供了以下值:蛋氨酸:1.57±0.06%，苏氨酸:2.34±0.08%，色氨酸:0.56±0.02 %，精氨酸:3.37±0.12%，组氨酸:1.32±0.02 %，异亮氨酸:2.35±0.05%，亮氨酸:4.27±0.32%，赖氨酸:4.34±0.27%，缬氨酸:2.71±0.09%，苯丙氨酸:通信M. Shamsaei，伊斯兰阿扎德大学渔业系，科学与研究分支，邮政信箱:14515-877，伊朗德黑兰。(Email: m.shamsaie@srbiau.ac.ir) 2.22±0.07%，甘氨酸:5.12±0.17%，丝氨酸:2.43±0.05%，脯氨酸:3.11±0.06%，丙氨酸:3.85±0.09%，半胱氨酸:0.53±0.15%，天冬酰胺:5.08±0.2%，谷氨酰胺:7.63±0.16%。与评估鲟鱼身体成分和氨基酸分布的一些国际标准相比，本研究显示鲟鱼养殖场的结果与粮农组织2011年发布的结果相同。总的来说，波斯鲟鱼不仅是蛋白质(即必需和非必需氨基酸)的宝贵来源，而且还可以帮助农民和研究人员根据他们的实际营养需求制定鱼类饲料。
