Abstract

This study investigates Alligator weed's nutritional value and potential application (Alternanthera philoxeroides) as a feed ingredient in herbivorous aquaculture. The nutrient composition of Alligator weed was analyzed, revealing a high content of crude protein (18.5g/100g), crude fiber (21.0g/100g), and essential minerals such as calcium (1,200mg/100g) and potassium (2,350mg/100g). Phytochemical analysis identified significant amounts of flavonoids (2.35g/100g) and phenolic compounds (3.80g/100g), indicating potential antioxidant properties. Antioxidant activity was assessed using the DPPH assay, with methanol extracts showing the highest activity (79.4% inhibition at 10mg/mL). The application of Alligator weed in aquaculture feed was evaluated in several herbivorous fish species, including tilapia, grass carp, silver carp, common carp, and freshwater prawns. Optimal inclusion levels were determined to be 20%, resulting in improved growth performance, feed conversion ratios (FCR), and survival rates across all species. The findings suggest that Alligator weed is a promising, sustainable feed ingredient that can enhance the health and productivity of herbivorous aquaculture species. Further research on long-term effects and commercial viability is recommended to fully harness its benefits.
