Abstract
The purpose of this study was to address the effect of using Moringa leaves as a source of feed protein on the growth and protein retention of gourami fish (Osphronemus gouramy). The treatment included five different substitutions of Moringa leaves (Moringa oleifera) for artificial feed, namely 0; 25; 50; 75 and 100 (%). The experimental design used was a completely randomized design with 5 treatments and 3 replications. Data analysis using quantitative methods included survival rate, specific growth rate and protein retention. The data were analyzed using analysis of variance (ANOVA) to test the effect of treatment, followed by Tukey's test for multiple comparisons. Ten fish were used per treatment group, with an average initial weight of 19.09 ± 0.39 g. The results indicated that the optimal addition of Moringa leaf flour was a 50% substitution of pellet feed, based on a survival rate of 83.33%, a specific growth rate of 0.66 ± 0.03% per day, and protein retention of 16.25 ± 0.17%.
