Abstract Legal restrictions and consumer trends are contributing to the growing movement for fish welfare. Therefore, aquaculture sector is a means of reducing animal stress enhancing physiological state, which raises financial profits. Feed additives have therefore been suggested as possible dietary alleviation. In this trend, 75-day feeding trial was conducted evaluate effects three organic acids (formic acid (FA), lactic (LA), commercial mix (COM)) in Nile tilapia ( Oreochromis niloticus...

High feed prices and limited access to are two critical problems faced by fish producers. One approach that farmers may consider is using less expensive locally available components. We conducted a 60-day feeding trial investigate the consequences of dietary addition Hemicell® (HC) as exogenous β-mannanase lavender flower meal (LFM) in low- protein diet (25 % CP) Oreochromis niloticus. The investigation assessed growth, utilization, somatic, body composition hemato-biochemical indices,...

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;...

First report on using chamomile (Matricaria chamomilla) flower meal [CFM] and marjoram (Origanum majorana) leaves [MLM] as dietary supplements in low-protein fish diets Nile tilapia (Oreochromis niloticus) reared a bio-floc system. The experiment consisted of 6 groups triplicates, where the first (T1) second (T2) were fed containing 25 20% protein, respectively, without any additives. In contrast, rest protein diet, adding CFM at rates 1% (T3) 2% (T4) or MLM (T5) (T6). initially weighed...
