Efektivitas Penggunaan Ikan Petek dan Daun Kelor Pada Pakan terhadap Pertumbuhan dan Sintasan Ikan Nila Effectiveness of petek fish and moringa leaf meal in diets on growth and survival of tilapia

Abstract

Feed plays a crucial role in tilapia aquaculture; however, high feed costs, driven by dependence on imported ingredients, have spurred the search for local alternatives. Petek fish and Moringa leaves are potential sources of animal and plant-based protein for fish feed formulation. This study aimed to evaluate the effectiveness of Petek fish and Moringa leaves in feed on the growth performance and survival of tilapia. A Completely Randomized Design (CRD) was used, consisting of four treatments and three replications, namely: commercial feed (A), 30% Petek fish + 10% Moringa leaves (B), 20% Petek fish + 20% Moringa leaves (C), and 10% Petek fish + 30% Moringa leaves (D). Data were analyzed using Analysis of Variance (ANOVA) followed by a W-Tukey post hoc test. Results showed that the average absolute weight gain (AWG) was 4.86 grams (C), 3.63 grams (A), 2.86 grams (B), and 2.45 grams (D), respectively. The average specific growth rate (SGR) was 3.77%/day (C), 3.21%/day (A), 2.77%/day (B), and 2.46%/day (D). The survival rates were 97.77% (C), 95.55% (B) and (D), and 64.44% (A). Analysis of variance (ANOVA) showed that the treatment had a significant effect on AWG, SGR, and survival rate (P < 0.05). The W-Tukey post hoc test indicated that AWG and SGR in treatment C differed significantly from B and D, but not significantly different from A, while survival treatment A differed significantly from B, C, and D, but B, C, and D showed no significant differences. The treatment of 20% Petek fish + 20% Moringa leaves (C) was the most effective combination in increasing AWG, SGR, and survival of tilapia
