The alarming rise in microbial drug resistance necessitates an urgent search for effective alternative antimicrobial agents that exhibit minimal cytotoxicity in humans. Curcumin, the active compound derived from turmeric, has demonstrated broad-spectrum biological activities, including antibacterial, antifungal, antiviral, and antiprotozoal effects. This study investigated the antifungal efficacy of nanocurcumin as a dietary supplement in sturgeon. The experimental design included four treatments: a control diet (T1), and diets supplemented with 25 (T2), 50 (T3), and 75 (T4) mg/kg nanocurcumin. Sampling was conducted on days 0, 7, 14, 28, and 56 of the feeding trial. The results indicated that dietary nanocurcumin reduced the fungal load in the feed compared to the control group. In conclusion, nanocurcumin is a potent natural antifungal agent that can effectively improve feed safety and quality in sturgeon aquaculture.
