Effect of Various Leaf Meal Supplementation as a Source of Plant-Based Protein on the Growth of Red Tilapia (Oreochromis niloticus)

This study aims to evaluate the effect of adding various types of leafy greens in artificial feed formulations on the growth rate of red tilapia (Oreochromis niloticus) fingerlings. The research was conducted from January to March 2023 at the Aquatic Resource Management Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Jatinangor. The research method used was an experimental design with a Completely Randomized Design (CRD), consisting of five treatments with three replications each. The treatments included: Treatment A (control/no leafy green addition), Treatment B (10% Carica papaya leaf meal), Treatment C (10% Alocasia macrorrhiza leaf meal), Treatment D (10% Albizia falcataria leaf meal), and Treatment E (a combination of 3.33% the three various leaves). The results showed that the addition of leafy greens in the feed did not result in significant differences in growth rate and feed efficiency. However, the treatment with 10% Alocasia macrorrhiza leaf meal produced the highest daily growth rate at 1.22% and a feed efficiency of 26.21%. Based on these results, it can be concluded that adding up to 10% leafy greens in feed formulations can be considered an alternative source of plant-based protein for red tilapia fingerlings.
