The research was conducted at the Laboratory of Fisheries Product Technology, STPL Palu, and the Laboratory of FMIPA, Tadulako University. Chemical quality analyses included moisture, ash, protein, lipid, carbohydrate, and crude fiber content based on AOAC (2005) methods. Phytochemical tests were carried out to identify the presence of bioactive components, including flavonoids, saponins, tannins, phenolics, triterpenoids, and steroids. The results showed that the addition of seaweed flour increased the levels of moisture (2.00–6.00%), ash (2.67–5.33%), protein (22.13–29.14%), carbohydrates (19.14–22.54%), and crude fiber (0.96–3.90%). Conversely, lipid content decreased with the increasing addition of seaweed flour, from 19.89% to 17.49%. All chemical quality parameters were still in accordance with the quality standards of SNI 7762-2013. Phytochemical analysis confirmed the presence of bioactive compounds such as flavonoids, saponins, polyphenols, tannins, and alkaloids in the fortified samples, while steroids were not detected. These compounds are known to possess antioxidant activity and important pharmacological benefits, thereby reinforcing the potential of frigate tuna amplang as a functional food. The findings highlight that fortification with E. cottonii seaweed flour can enhance nutritional value, enrich fiber content, and increase the bioactive compounds of frigate tuna amplang.
