| Abstract | ||||
| The global production of vaname shrimp (Litopenaeus vannamei) reaches 6.8 million tons, making it a major species in the aquaculture industry. However, the success of this culture is often threatened by Vibriosis disease caused by Vibrio sp. This study aimed to analyze the relationship between water quality parameters and Vibrio sp. bacterial abundance in intensive vaname shrimp ponds. Water quality measurements were conducted every seven days including temperature, dissolved oxygen, salinity, and pH, while Vibrio sp. density was calculated using selective culture method and PCR confirmation. The results showed that Vibrio sp. abundance had a significant correlation with water quality parameters, especially temperature (r = -0.622), dissolved oxygen (r = -0.378), pH (r = 0.377), and salinity (r = 0.597). Vibrio sp. density increased with rearing time and showed the highest value at 30ppt salinity and 30°C temperature. In addition, detection of Vibrio genes related to Acute Hepatopancreatic Necrosis Disease (AHPND) showed positive results even though Vibrio parahaemolyticus was not detected in pond water samples. This study confirms that environmental factors play an important role in Vibrio sp. dynamics and need to be properly managed to prevent disease outbreaks in vaname shrimp intensive culture systems. | ||||
