Abstract

White shrimp (Litopenaeus vannamei) culture in Indonesia has been well developed since 1999.  Among the problems occurred during the culture period in the hatchery, Zoea Syndrome (ZS) is the most serious.  An observation has been done to determine the prevalence and the clinical signs of this syndrome. Nauplii were collected from hatcheries in East Java (3 hatcheries) and Central Java (1 hatchery) and subject to PCR test in order to obtain TSV free nauplii.  The results showed that TSV free nauplii could also be infected by ZS, where the prevalence could reach 100%.  There was also a possibility that Vibrio sp. was involved in  ZS infection.

Abstract

Vibrio spp. is one of the common pathogens that infects shrimp hatchery and rear, which can cause mass mortality of fry in shrimp hatchery. This study aimed to determine the dynamics of Vibrio spp. in sea water around seven areas of vannamei shrimp hatchery centers in Indonesia. Observations were conducted every month from January to December 2020, by inoculating 100 µL of sea water samples onto thiosulfate-citrate-bile-salt sucrose (TCBS) agar media, incubating at 30°C for 18–24 hours, after which Green Vibrio Colony (GVC), Total Vibrio Count (TVC), and the percentage of luminescence bacterial were counted in sea water samples. Observation results showed that the highest GVC and TVC occurred in Takalar sea water in May 2020, while the highest percentage of luminescence bacterial obtained in samples from Pantai Cermin-Serdang Bedagai sea water. The GVC value ranges between 0,01–130,00 × 102 CFU/mL with the highest numbers occurring in January, October, November, and Desember 2020, while the TVC value ranges between 0,20–520,00 × 102 CFU/mL throughout 2020. No luminescence bacterial was found in sea water samples from the Anyer and Pangandaran areas. Vannamei shrimp hatchery operators need to always be aware of the population dynamics of Vibrio spp. bacteria in sea water that will be used in vannamei shrimp hatchery activities.
