This study investigates the Condition Index (CI) and Feed Conversion Ratio (FCR) of Angel Fish(Pterophyllum scalare) cultured under two different feeding conditions over an eight-month rearing period.Two types of feed were utilized namely traditional fish feed and alternative feed incorporating Black SoldierFly (BSF) larvae. This study assessed the impact of these diets on fish growth, health, and feed efficiencyconsidering CI and FCR as proxies. We used a Python Streamlit app for calculations related to CI and FCR.The findings suggest significant differences in CI and FCR between the two groups, providing insights intosustainable and cost-effective aquaculture practices.
