Summary
This study investigates the effects of supplementing Nile tilapia (Oreochromis niloticus) diets with Andrographis paniculata leaves extract on both productive performance and the nutritional quality of the fish, with particular focus on omega-3 fatty acid enrichment. Andrographis paniculata is a medicinal herb with known bioactive compounds (notably andrographolide) that may influence lipid metabolism and immune function in fish. The paper likely demonstrates that targeted phytogenic supplementation can modulate fatty acid profiles in farmed tilapia, with implications for the nutritional value of fish products for human consumption.
UK applicability
Nile tilapia is not a commercially significant farmed species in the UK, and Andrographis paniculata is not a native or widely cultivated plant in British conditions; however, the findings are relevant to UK aquaculture research and the broader interest in phytogenic feed additives as alternatives to synthetic supplements in sustainable fish production.
Key measures
Weight gain (g); specific growth rate (%/day); feed conversion ratio; omega-3 fatty acid content (mg/g or % of total fatty acids); possibly survival rate (%)
Outcomes reported
The study likely measured growth performance indicators (weight gain, specific growth rate, feed conversion ratio) and the omega-3 fatty acid composition of Nile tilapia flesh following dietary supplementation with Andrographis paniculata leaves extract at varying inclusion levels.
