Summary
This 2025 study investigates the potential of Andrographis paniculata leaf extract, a traditional medicinal plant, as a dietary supplement to enhance both growth and nutritional quality in Nile tilapia aquaculture. As suggested by the title, the intervention appears to improve growth performance whilst favourably modifying the fish's fatty acid profile, particularly omega-3 content. Such findings, if confirmed, could offer tilapia producers a plant-based approach to improving both productivity and the nutritional value of a widely consumed farmed fish.
UK applicability
Whilst tilapia aquaculture is limited in the UK, findings on plant-based feed additives for improving fish nutritional composition may inform research on species farmed domestically (e.g. rainbow trout, sea bass). The methodology could inform UK-based research on functional feed ingredients and their effects on farmed fish quality.
Key measures
Growth performance (body weight gain, specific growth rate, feed conversion ratio); omega-3 fatty acid composition (as % of total lipids or mg/100g tissue); hepatosomatic index; survival rate
Outcomes reported
The study examined effects of dietary Andrographis paniculata leaf extract on growth performance metrics and omega-3 fatty acid profiles in farmed Nile tilapia. Measures likely included weight gain, feed conversion efficiency, and lipid composition analysis.
