Evaluation and Comparison of Fatty Acid Profile and Calcium, Phosphorus and Iron in Oreochromis niloticus, Arabibarbus grypus and Oncorhynchus mykiss

The aim of this study was to compare the fatty acid profile and calcium, phosphorus and iron in Oreochromis niloticus, Arabibarbus grypus and Oncorhynchus mykiss. For this purpose, 3 fish (9 fish in total) were analyzed. The results showed that the highest amounts of iron and calcium were obtained in A. grypus and O. mykiss with 3.73 and 26.19 mg/kg, respectively. O. mykiss, on the other hand, had the highest phosphorus content of 2.94 g/kg. Increasing the amount of ash can decrease the quality of meat in aquatic life, so the results showed that the lowest amount of ash belonged to A. grypus with 1.04% and O. niloticus and O. mykiss with 1.13%. The highest dry matter content was 28.26% in A. grypus. Also, A. grypus had the highest amount of unsaturated fatty acid (70.97%). O. mykiss and O. niloticus had 65.71% and 57.14% unsaturated fatty acids, respectively. Therefore, it can be stated that A. grypus has the highest amount of unsaturated fatty acids in terms of quality and calories needed by the human body compared to the other two fish. O. niloticus, with the highest palmitic acid content among the three species tested, clearly showed that the quality of this fish was very low compared to the other two fishes.
