Abstract

Pacific white shrimp (Litopenaeus vannamei) has advantages in terms of growth and rapid adaptation process to its environment. Shrimp are also very risky once exposed to pathogenic bacteria. This study aims to monitor the population density of Vibrio sp. and the health status of hepatopancreas in pacific white shrimp. This research was conducted for 80 days using 58 Pacific white shrimp. There are seven ponds which are intensive cultivation ponds with days of culture (DOC) from 10-80. Measurement of bacterial populations using the spread platting method. The hepatopancreas obtained was then observed the level of necrosis, the presence of gregarine, and the percentage of hepatopancreas depletion. The resulting data were analyzed descriptively qualitatively. The results showed the highest Vibrio sp. population came from DOC 70 which were sequentially found in P2 pond at 5.8x103 CFU/gr. The highest percentage of hepatopancreas depletion occurred at DOC 30, 50, and 80 which was 90%. The presence of necrosis can be confirmed by the appearance of lesions in the hepatopancreas. Gregarine was also found in this study after sneaking into pacific white shrimp hepatopancreas.
