N2 - This study aimed to evaluate Pacific white shrimp larval quality from several shrimp breeding centers in East Java. parameters measured include 1) bolitas, 2) abundance of Vibrio spp. (water and shrimp body), and 3) muscle gut ratio (MGR). Larval samples were collected from 8 hatcheries located in East Java. The results showed that the percentage of bolitas in the hepatopancreas organ of shrimp larval in ponds 6, 7, and 8, respectively was <35%. Larval guts were found in all hatcheries, except for the 2nd pond as many as 60%. The highest abundance of Vibrio spp. (yellow colonies) in water samples and fry bodies was found in the 6th pond (26.5 × 103 CFU mL-1) and the 4th pond (76.9 × 103 CFU gr-1). The abundance of Vibrio spp. (green colony) and the highest water sample was found in the 3rd pond (3.8 × 103 CFU mL-1), while the larval was not detected. The larval found the highest percentage of MGR in the 3rd pond (87.5%), and the lowest was in the 7th pond (57.50%). Overall, our results demonstrate the infection of Vibrio spp. has involvement in the incidence of zoea syndrome in pacific white shrimp fry in hatcheries.
