Abstract

White shrimp (Litopenaeus vannamei) is a leading aquaculture commodity in Indonesia whose production is often hampered by Vibrio parahaemolyticus infection, the causative agent of Acute Hepatopancreatic Necrosis Disease (AHPND) with mortality reaching 85–100%. This study aimed to determine the effect of immersion in jeruju leaf extract (Acanthus ilicifolius) on the immune response and survival of V. parahaemolyticus-infected white shrimp, and to identify its optimal concentration. A Completely Randomized Design (CRD) was used with five groups: negative control, positive control, and extract immersion at 200, 300, and 400 mg/L for 30 minutes. Data were analyzed using One Way ANOVA followed by Duncan's test. Results showed that jeruju leaf extract immersion significantly affected (p<0.05) THC, DHC composition (an increase in the proportion of granular cells), and post-infection survival rate. The 400 mg/L concentration (treatment C) produced the best results, with the highest THC of 15.08 × 10⁶ cells/ml, the highest proportion of granular cells at 65.67%, and the highest SR of 79.17%, compared to only 48.33% in the positive control. These findings demonstrate that jeruju leaf extract has potential as an environmentally friendly herbal immunostimulant for controlling V. parahaemolyticus infection in white shrimp aquaculture.

Abstract

Tilapia production is greatly influenced by feed as a source of energy and nutrients that support growth, health, survival, and reproduction. The growth rate of fish is closely related to feed quality, so that growth optimization can be achieved through the provision of quality feed. The ingredient that can be used as an alternative for optimizing feed quality is purple sweet potato flour (Ipomoea batatas L.). The purpose of this study was to determine the effect of commercial feed added synbiotics with different doses on the growth rate of tilapia. This study used a complete random design method with 3 treatments, with a maintenance duration of 56 days. Each treatment uses commercial feed, treatment 1 is control, treatment 2 is 1.5% prebiotic and probiotic 2%, treatment 3 is 2% prebiotic and probiotic 2%. The results of the assumption test stated that treatment 3 obtained a significant number as well as the highest score with an absolute weight of 28.59, SGR of 3.32, FER of 78.4, FCR of 1.28. This value illustrates that synergibiotic feed has the potential to improve the quality and quality of feed which leads to the growth rate of tilapia.
