Lemna minor is a floating aquatic plant with a high protein content, making it a potential substitute for fishmeal in formulated fish feeds. This study aimed to evaluate the utilization of L. minor meal as a partial replacement for fishmeal and to provide supporting information regarding its application in aquaculture. Feed formulations were prepared with L. minor meal at substitution levels of 10% and 20%, and tested using a completely randomized design with three replicates, employing Nile tilapia as the test organism. The results showed that the 10% substitution level produced the best growth performance, with a 0.53% higher growth rate compared to both the control and the 20% substitution. Additionally, the inclusion of L. minor meal improved feed buoyancy and water stability. These findings indicate that L. minor meal has promising potential as a feed ingredient to reduce the reliance on relatively expensive fishmeal.
