Determination of amino acid and fatty acid profiles of bogue (Boops boops) fished in the Gulf of Antalya

Abstract

Our study aimed to establish the monthly changes of bogue fatty acids and amino acids (Boops boops Linnaeus, 1758) economically important species during the fishing season. According to the results of the fatty acid analysis of bogue; the highest values were detected for C20:4 ω-6 (arachidonic acid) in December (6.50%), EPA (eicosapentaenoic acid) C20:5 ω-3 in September (5.45%), DHA (docosahexaenoic acid) C22:6 ω-3 in March (16.36%), ΣMUFA (total monounsaturated fatty acid) in April (36.57%), ΣPUFA (total polyunsaturated fatty acid) in November (31.81%) and EPA+DHA in March (19.61%). The highest EPA, DHA and total ω-3 values were observed in March. Amino acid values usually showed important monthly variation (P<0.05). EAA (Essential amino acids) such as lysine (4038.5 mg/100g), valine (1126.5 mg/100g) and leucine (1737.5 mg/100g) contents of bogue were detected in February as the highest values. Glutamic acid and aspartic acid from the NEAA (Non-essential amino acid) values were found highest amount in April. Fatty acids and amino acid values, obtained from the bogue samples changed monthly and were generally significant (P<0.05).
