Data were analyzed descriptively using Microsoft Excel 2021. Reference validation was based on ISSN and DOI verification. Literature selection, classification, and data extraction were performed systematically following PRISMA guidelines to ensure research reliability.</p> <p style="text-align: justify;"><strong>Main Findings: </strong>The main findings show that Roselle (<em>Hibiscus sabdariffa</em>) contains bioactive compounds such as anthocyanins, flavonoids, and vitamin C that enhance fish health and immunity. Supplementation improved survival rate and feed intake but did not significantly increase color performance, as anthocyanins are not dominant pigments for coloration compared to carotenoids like astaxanthin and zeaxanthin.</p> <p style="text-align: justify;"><strong>Novelty/Originality of this study: </strong>This study provides new insight into the potential use of Roselle (<em>Hibiscus sabdariffa</em>) as a natural feed additive for ornamental fish. Unlike previous studies focused on food fish, it highlights Roselle’s bioactive compounds in enhancing immunity and feed intake, offering an eco-friendly alternative to synthetic additives in sustainable aquaculture practices.</p> Phichamon Noisuwan, Muhammad Ijaz, Setyawan Heru Tandyo Copyright (c) 2025 Phichamon Noisuwan, Muhammad Ijaz, Setyawan Heru Tandyo https://creativecommons.org/licenses/by/4.0 https://cahaya-ic.com/index.php/JOUABE/article/view/2243 Tue, 24 Jun 2025 00:00:00 +0700
