Nutraceutical based on algae and enzymatic-bacterial extracts (symbiotic activity). Intended for aquaculture species. Prepared for use in aquatic environments. Stabilising, thickening and gelling action, with great capacity to regulate intestinal transit. In larval cultures, it has shown a 30% increase in survival and growth in length and body mass.
