Abstract Prioritizing water management and maintaining its quality for as long possible, while lowering related stressors, are crucial sustainable aquaculture. To achieve this equilibrium, enriched aquafeed with natural immunostimulants is essential to success. In trend, 6 weeks feeding trial was conducted evaluate the effects of Ceratonia siliqua syrup (CSS) Zingiber officinale powder (ZOP) in Nile tilapia ( Oreochromis niloticus ) reared under a zero-water exchange. The immune-antioxidant, growth, physiological responses, antioxidant/inflammatory pathways-associated genes well ammonia tolerance were evaluated. Fish (weighing 25.85 ± 1.42 g) randomly housed into six groups n = 30 fish/group; ten fish/replicate; three replicates/group). control group fed basal diet without any additives. second (CSS1.25) supplemented 1.25% CSS. third (ZOP0.5) fourth (ZOP1) diets 0.5 1% ZOP. fifth (CSS1.25 + ZOP0.5) sixth ZOP1) CSS or All treatments kept exchange weeks. Findings revealed most notable improvement P < 0.05) growth rate (final body weight specific rate) survival fish dietary ZOP CSS1.25 ZOP0.5 diets. Hepato-renal markers (alanine aspartate aminotransferases, urea, glucose, cortisol) lipid peroxides (malonaldehyde) declined by and/or Immuno-antioxidants (immunoglobulin M, lysozyme, superoxide dismutase (SOD), reduced glutathione) significantly boosted ZOP1 groups. addition, markedly upregulated antioxidant-linked SOD glutathione peroxidase) downregulated stress gene (heat shock protein 70) pro-inflammatory cytokines (interleukin-1β tumor necrosis factor-alpha). decreased mortality during stress. reported having best outcomes throughout measured indices. Overall, our findings demonstrate that at optimum doses can improve immune response, functions O. stressful conditions (unchanged water) aquaculture industry.

Phytobiotics are promising diet alternatives, yet their effectiveness in high-risk aquaculture conditions remains underexplored. Therefore, a 90-day feeding trial was conducted based on dietary supplementation of Nile tilapia, Oreochromis niloticus , with herbal extracts, namely, lemon balm [ Melissa officinalis (MOE)], marjoram Origanum majorana (OME)], and chamomile Matricaria chamomilla (MCE)] 0% water change. The treated groups were compared to untreated herbs or control [positive (PC; change) negative (NC; 20% exchange per day]. Fish cultured at stocking density (20 fish m -3 : 1.8kg biomass/m3). We physicochemical analysis the clinical responses, growth, immune responses evaluated. Furthermore, herbal-supplemented then challenged pathogenic Edwardseilla tarda strain mortality monitored. In 1 st 2 nd months, parameters within permissible limits. After that, fatally low dissolved oxygen concentration highest levels ammonia, nitrite, nitrate, pH recorded during 3 rd month. Blood assays groups. herbal-treated appeared healthy, but 3rd month, lethargy decreased appetite evident. Generally, showed improved growth performance parameters, survival rates, resistance against bacteria E. particularly OME MOE-treated positive group. Finally, phytobiotic supplements shown improve stress tolerance activation for certain period under stressful unchanged water, density, dosages used, extent deterioration quality.
