Abstract: Nike is a small fish of juvenile schooling of Awoaus melanocephalus which is being plenty in Gorontalo water. That fish was a fish consumption in the Gorontalo area highly appreciated by the public because it was delicious and savory. The early research on nike fish known that these fish were juveniles of Awaous melanocephallus fish species. The fish were always in large numbers and in the schooling form. That fish was an anadromous fish. Studies conducted on nike fish in Gorontalo Waters is still very limited. Study of the chemical compotition of fish is not done, so this study aimed to characterize the chemical composition of nike fish ie proximatre composition, amino acids, fatty acids, as well as some types of essential minerals. The study result show that the nike fish’s nutritional composition consisting of proximate that was 79.76% water, protein 16.89%, fat 0.76%, 0.3% carbohydrate, and ash 1.93%. The highest concentration of essential amino acid was conceived by 1.153% leucine and 0.843% lysine, and the highest concentration of non-essential amino acids contained by amino acids glutamate and proline that is 1.478% and 0.821%. Unsaturated fatty acid content of nike high enough that composed dekosaheksanoat acid (DHA) 14.81%, 8.50% oleic acid, and eikosapentanoat acid (EPA) 2.22%. Mineral composition of nike consisted of calcium 677.34 ppm, 211.58 ppm magnesium, iron 15.77%, 17.88 ppm zinc, iodine 0.079 ppm.
