Effect of fermented water hyacinth (Eichhornia crassipes) on growth performance of fish

Water hyacinth is an aquatic plant, which can grow rapidly along the water area with rich of nutrients. Mostly this plant be alternative ingredient for fish feed because it contains various nutrients such as proteins, carbohydrates, lipids, minerals, amino acids, fatty secondary metabolites. However, plant-based, fiber and anti-nutritional factors tannins phytic acids degrade quality decrease growth performance if used in high concentration. fermentation a solution to increase digestibility nutrient contents. Several studies showed that fed by fermented better than non-fermented. The concentration, apply ingredient, ranged 20-40% replacement.
