<![CDATA[Nile tilapia (Oreochromis niloticus) is one of the most economically important freshwater aquaculture commodities in Indonesia. In aquaculture production, feed accounts for the largest proportion of production costs, representing approximately 60–70% of the total operational expenses. Therefore, improving feed efficiency without compromising fish growth performance has become a major concern in tilapia farming. This article aims to analyze the efficiency of commercial feed and formulated feed on the growth performance of Nile tilapia based on findings from previous studies. The study employed a literature review method by examining national and international scientific publications related to fish growth, feed conversion ratio (FCR), feed efficiency, and survival rate. The review indicates that commercial feed generally provides consistent growth performance due to its balanced and standardized nutritional composition, whereas properly formulated feed can achieve comparable growth when prepared with appropriate ingredient proportions and nutritional balance. In addition, the use of formulated feed has the potential to reduce production costs, making it a more economical alternative for fish farmers while maintaining satisfactory growth performance.]]>
