Abstract

In mid-2021, shrimp farmer reported case of mass deaths in white shrimp (Litopenaeus vannamei) in Pasuruan Regency, reaching 2.6-3 kg/day in Kalianyar Village, Bangil District. To determine the main pathogenic bacteria that cause mass mortality and the composition of microbes on rearing media infected with certain diseases and healthy ones, this study observed the water profile of ponds which include microbial composition in it using next-generation sequencing (NGS) technology. The research was conducted by taking healthy shrimp pond water samples and infected shrimp pond water samples. These results generally indicate that the disease is similar to white feces syndrome (WFS). The results of the NGS test showed that the main causative pathogen is Vibrio vulnificus because its presence in infected pond water is quite dominant.
