- Functional Potential of Red Dragon Fruit () Juice By-Products as a Natural Feed Additive for Juvenile Red Seabream (): Implications for Antibiotic-Free Aquaculture. Oh, Hwa Yong Kim, Ki-Tae Lee, Tae Hoon Kang, Da Ye Kwon, Do-Hyun Kim, Young Wook Kim, Hee Sung The extensive use of antibiotics in aquaculture has raised serious concerns, emphasizing the need for sustainable and natural alternatives. This study evaluated the potential of red dragon fruit () juice by-products (RJB) as a functional feed additive for juvenile red seabream (). The bioactive composition and antioxidant capacity of RJB were analyzed, and five experimental diets containing 0, 0.2, 0.4, 0.8, and 1% RJB were fed to fish for 56 days. Growth performance, feed utilization, body composition, antioxidant enzyme activities, and lysozyme activity were evaluated. RJB contained substantial levels of phenolic and flavonoid compounds and exhibited strong radical-scavenging activity. Dietary inclusion of up to 1% RJB did not significantly affect growth, feed efficiency, or plasma biochemistry. However, fish fed the 1% RJB diet showed increased catalase and glutathione levels, significantly enhanced lysozyme activity, and improved survival following infection. These results demonstrate that RJB can be safely incorporated into marine fish diets to enhance antioxidant capacity and innate immune defense. The valorization of fruit-processing by-products such as RJB offers a promising strategy for developing antibiotic-free and sustainable aquaculture practices.
