The science behind Bioful Aqua
Research has shown that fulvic acid significantly improves survival rates, lowers the stress response in fish, and reduces the feed conversion ratio. The science behind Bioful Aqua is supported by peer-reviewed research on fulvic acid from several reputable institutions.
Backed by independent scientific research
Six independent peer-reviewed trials, six species, consistent direction of effect of fulvic acid.
What the evidence shows, across studies.
-
Higher survival rates under disease challenge and at the larval stage — confirmed in seabass, croaker, and salmon trials.
-
Improved feed conversion ratio (FCR) and faster growth across trout, tilapia, and seabass — dose-dependent and reproducible.
-
Stronger innate immunity — elevated lysozyme, complement, and SOD activity in five of six studies.
-
Lower stress response — reduced cortisol and oxidative stress markers under transport and handling conditions.
-
Healthier gut microbiota — increased Lactobacillus abundance and digestive enzyme activity in 60-day feeding trials.
-
Optimal dose range identified — benefits observed at 1.5%–5 g/kg in feed; in-water application effective at trout-relevant concentrations.

Selected studies on fulvic acid from leading aquaculture and freshwater research institutions. Click any card to open the study.
Egg survival 95.5% vs 81.8%; fungal load down.
5 mg/L bath, fertilisation through hatch. Reduced Flavobacterium and Aeromonas in tray incubators.
Skin lysozyme +3.2×; IgM +77%; activity vs Yersinia ruckeri.
Bath at 50 mg C/L. First salmonid skin-mucosal trial. Direct activity against the enteric redmouth pathogen.
Growth + FCR improved on dietary FA; lysozyme and antioxidant defences up.
8-week feeding trial. Best gains at 0.5 – 1% inclusion. Lysozyme, GPx, and catalase all elevated.
Growth + immune markers up; higher survival under Vibrio challenge.
225 fish, 15 tanks. Optimum at ~4.4 – 5 g/kg. Improved lysozyme, complement, and SOD activity.
Larval survival and growth up; digestion and innate immunity improved.
30-day larval trial. Improved protease activity and lysozyme.
Strongest microbiota shift; digestive enzyme and immune boost at ~1.5%.
60-day feeding trial with gut microbiota profiling. Increased Lactobacillus abundance.
