Nile tilapiais (Oreochromis Niloticus) popular among fish farmers because it is easy to raise, grows quickly, and does not require specific environmental conditions for cultivation. Based on its morphology, nile tilapiahas a length-to-height ratio of 2:1 and a body height-to-width ratio of 4:1. Its color is grayish-black. In aquaculture, feed is one of the most critical factors to consider, as it provides the primary energy source for growth. In this study, an experiment was conducted to test the effects of different types of pellet feed on nile tilapia fingerlings as treatments, namely Treatment A (100% Feed A), Treatment B (100% Feed B), and Treatment C (50% Feed A + 50% Feed B). The objective of this study was to determine which feed type could optimally promote the absolute length growth of nile tilapia. The experimental design employed a completely randomized design with 3 treatments and 9 replicates, yielding 27 experimental units. Using different types of feed, the average absolute growth results were obtained, namely treatment A (100% Feed A) with an average absolute growth of (46.567 cm), followed by treatment C (50% Feed A + 50% Feed B) with an average absolute growth of (44.422 cm), and the lowest in treatment B (100% feed B) with an average absolute growth of (41.511 cm).
