Abstract

Introduction: Good food supply or quality, stable and reasonable price, is one of the main and important problems in the aquaculture industry. In recent years, much research has been done on the use of different species of algae as a source of protein in the aquatic diet. The present study was performed to evaluate the chemical composition, amino acid and premix fatty acid of the premix of brown macroalgae Padina australis, Sargassum ilicifolium and Stoechospermum marginatum.

Materials & Methods: In this study, after collecting macroalgae from the tidal areas of Chabahar coast, they were washed and after drying in a ratio of 1: 1: 1, they were combined and turned into powder. Chemical composition was measured by AOAC method, fatty acids by chromatography and amino acids by HPLC.

Results: The results showed that the amount of protein, fat, ash and moisture were 8.43, 1.30, 21.26 and 68.01%, respectively. The main component of the macroalgae premix tested was moisture. The predominant saturated fatty acids in the macroalgae premix were palmitic acid (17.11 ± 0.31%), myristic acid (11.43±0.15%) and stearic acid (6.62±0.32%) were respectively. The ratio between non-essential amino acids to essential amino acids was 1.05 .Among monounsaturated fatty acids, oleic acid (17.21±7.21%) and among long-chain unsaturated fatty acids (PUFA), respectively, arachidonic acid (11.24±7.03%), linoleic Acid (9.12±3.21%) and eicosapentaenoic acid (8.13±0.68%) were predominant. The total essential and non-essential amino acids were 6.78 and 7.15 mg amino acids per gram of sample, respectively. Aspartic acid (1.88±0.05 mg amino acid per gram of sample) and glutamic acid (1.98± 0.05 mg amino acid per gram of sample) were the predominant nonessential amino acids.

Conclusion: In general, the results of this study showed that due to the presence of longchain unsaturated fatty acids and the balance between non-essential and essential amino acids, the use of premix of Padina australis, Sargassum ilicifolium and Stoechospermum marginatum macroalgae is recommended in aquatic nutrition.
