Growth of Vannamei Shrimp (Litopenaeus vannamei) Challenged by Vibrio parahaemolyticus Bacteria with addition of Moringa oleifera Leaf Powder through Feed

Aims: To determine the effect of different feeding doses supplemented with Moringa leaf powder (Moringa oleifera) on the growth of vannamei shrimp infected with Vibrio parahaemolyticus. Study Design: Quantitative Experimental. Place and Duration of Study: This study was conducted over a period of 60 days, from January to March, at the Fish Health Laboratory, Aquaculture Study Program, University of Mataram, West Nusa Tenggara, Indonesia. Methodology: This research is using a Completely Randomized Design (CRD), consisted by 5 treatments and 3 replications, resulting in a total of 15 experimental units. The treatments applied are addition moringa leaf powder (MLP) at different doses/kg food (0%, 2%, 4%, and 6%). Shrimp cultivation was carried out for a period of 45 days. On the 46th day, the shrimp were subjected to a challenge test using Vibrio parahaemolyticus bacteria to evaluate the immune response of the shrimp that had been added MLP according to their respective treatment groups. Results: The results of this research showed that the addition of moringa leaf powder (MLP) to feed at different doses had a significant effect to the parameters. Treatment 5 (P5-6% MLP addition) resulting survival rate 85%, specific weight growth rate 1.65%/day, specific length growth rate 2.3%/day, FCR 1.33, and phagocytic activity (PA) 74%. Treatment 5 (P5) statistically different to other treatment. Conclusion: The addition of Moringa leaf powder through feed had a significant effect on survival rate, specific weight growth rate, specific length growth rate, FCR, and phagocytic activity.
