Abstract

The presence of vibrio bacteria in the breeding pond is one of the important factors that affect the activities of vaname shrimp breeding. Vibrio sp. bacteria in waters can cause losses if the number is above the threshold that should be. The high abundance of Vibrio sp. bacteria in the cultivation environment is an indicator that shows the potential for disease that can reduce the growth rate and survival of shrimp. The purpose of the study was to determine the abundance and dominance of vibrio bacteria in vaname shrimp breeding ponds using the TPC (Total Plate Count) calculation technique. The methods used include bacterial sampling, preparation of tools and materials, making bacterial culture media (NA and TCBS), dilution, bacterial inoculation, and calculating the number of bacterial colonies. The results of the calculation of bacterial abundance showed that there were 9 breeding ponds with different abundances. The highest abundance was found in pond BV1 with a total bacterial value of 9.6 x 105 CFU/ml. Meanwhile, the highest vibrio dominance was found in pond BV4 with a percentage of 43.69%.

Abstract

The sustainability of Nile tilapia production faces challenges from motile Aeromonas septicemia (MAS), caused by Aeromonas hydrophila. The use of antibiotics to control MAS has negative impacts on aquatic environments and consumer health. As alternatives, plant-based treatments and vaccination have been increasingly applied to replace antibiotics. This study aimed to evaluate the effects of banana pseudo-stem (BS), a commercial vaccine (CV), and their combination (BS+CV) on the growth, health status, and immune performance of Nile tilapia against A. hydrophila. A completely randomized design was used with five treatments: a negative control (C−), a positive control (C+), BS, CV, and BS+CV—each coated onto feed. Each treatment had three replications. Fish were reared in 36-L aquaria for 42 days to evaluate growth performance, followed by a challenge test with A. hydrophila on day 43. Survival was monitored for 14 days post-challenge. The highest growth performance was observed in the BS treatment compared to the other treatments. Meanwhile, survival rate (SR) and feed conversion ratio (FCR) did not show significant differences (P>0.05) among treatments. After the challenge, survival rates in the BS (96.67%), CV (73.33%), and BS+CV (76.67%) groups were significantly higher (P<0.05) than in the positive control group (50.00%). The BS group did not differ significantly (P>0.05) from the negative control group (100.00%). These findings indicate that BS, CV, and BS+CV enhance the immune response of Nile tilapia against A. hydrophila, with BS being the most effective in improving both growth and disease resistance.

Abstract

Early Mortality Syndrome (EMS) or Acute Hepato Pancreatic Necrosis Disease (AHPND) caused by the pathogenic bacteria Vibrio parahaemolyticus (V. par) causes mass deaths in shrimp farming. This study aims to obtain the effective dose of shallot skin extract as a treatment for Pacific whiteleg shrimp infected with V. par RfR (rifampicin resistance 50 µg mL- 1). This research was conducted at the Pilot plane Faculty of Agricultural Technology and Laboratory of Aquatic Animal Health Management, Jepara Centre for Brackish Water Aquaculture (BBPBAP). This study used a Completely Randomized Design (CRD) consisting of five treatments and three replications, namely K- (negative control), K+ (positive control), KBM6,25 (shallot skin extract 6,25%), KBM12,5 (shallot skin extract red 12,5%), and KBM25 (shallot skin extract 25%). This research used Pacific whiteleg shrimp 3,41 ± 0,73 g fish-1,which were injected with V. par RfR bacteria and continued with 14 days of maintenance. The results showed that administration of shallot skin extract at a dose of 6,25% resulted in total haemocyte count (THC), differential haemocyte count (DHC), phagocytic activity (AF), reduction in the number of V. par RfR bacteria, survival rate, and feeding ratio which were significantly different compared to the positive control. Meanwhile, the clinical symptoms caused by treatment with shallot skin extract at doses of 6,25%, 12,5% and 25% recovered on the 14th day compared to the positive control, which still experienced clinical symptoms of infection.
