Abstract :

Abstract[1] Black mouth croaker (Atrobucca nibe) is considered as a new and valuable fish resource in the mesoplagic layers of the Oman Sea. In this study, microelements (i.e. iron, copper, zinc and manganese) and macroelements (i.e. calcium, magnesium, potassium and sodium) by using microwave digestion and atomic absorption device and also amino acids profile (using high performance liquid chromatography) in edible portion of the fish were determined. Among the macroelements, the maximum and minimum concentrations were recorded for potassium (168.67±0.314 ppm) and calcium (11.82±0.028 ppm), respectively. Microelements, which regard to their amount in the muscle, can be ordered in the following fashion: Fe>Zn>Cu>Mn mg/kg dry weight. Total essential and non-essential amino acids were calculated 8.96±0.230 and 9.71±0.218 g/100g wet weight, respectively. The glutamic acid showed the highest amount of amino acids measured in this study rather than other detected amino acids (3.73±0.269 g/100g wet weight) (P<0.05). Analyzes showed that the fish meat could be a valuable source of iron, zinc and essential amino acids. The heavy metal concentrations in the fish muscle were lower than accepted levels of international standards. * Corresponding Authors; Email: [e-mail]
