<![CDATA[Intensive culture of Nile tilapia in saline environments often faces major constraints, including water quality deterioration, proliferation of Vibrio spp., and physiological stress that impairs growth performance. Plant-based materials have recently gained attention as sustainable additives to improve aquatic environments and enhance fish health. This study aimed to evaluate the effects of chopped banana stem, taro leaves, and their combination on water mineral composition, Vibrio spp. abundance, blood glucose levels, and growth performance of Nile tilapia reared in saline conditions. The experiment was conducted over 30 days using four treatments: control (CO), banana stem (BS), taro leaves (TL), and their combination (BT, 1:1), each applied at a dose of 5 g/L with three replicates. Fifteen tilapia fingerlings were stocked in each container. The results showed that the application of plant materials significantly increased water mineral concentrations compared to the control. The BS treatment resulted in a significant reduction in Vibrio spp. abundance. Blood glucose levels remained relatively stable across all treatments. Growth parameters, including final weight, weight gain, and daily growth rate, were significantly improved in the treated groups, although survival rate did not differ significantly. Overall, the application of banana stem and taro leaves improved water quality, suppressed Vibrio spp. abundance, maintained physiological balance, and enhanced the growth of Nile tilapia.]]>
