Abstract

Viral infections are a major obstacle in the propagation of the tiger shrimp, Penaeus monodon, in Indonesia. This study investigates the occurrence of viral agents in tiger shrimp broodstock collected along the coast of Sulawesi, Indonesia including Makassar, Pangkep, Takalar, Pinrang and Bombana. Broodstock (n = 137) were examined for white spot syndrome virus (WSSV), monodon baculovirus (MBV), infectious hypodermal and hematopoietic necrosis virus (IHHNV) and hepatopancreatic parvovirus (HPV). Broodstock showed single viral infections: MBV (3.8-77.8%), IHHNV (3.7-20%), double infections: WSSV/MBV (3.7-15.4%), MBV/IHHNV (6.7-26.9%), MBV/HPV (3.7%), and triple infections: WSSV/MBV/IHHNV (3.3-53.8%). Mixed infection of WSSV with other viruses was found to be the highest in Takalar waters with a percentage of infection of 69.2%. Mixed infection of MBV and mixed infection of IHHNV were also high in Takalar with percentage of 100% and 80.8%, respectively. Single infection with WSSV and HPV were not observed. Furthermore, Bombana broodstock that were spawned, their progeny also showed multiple viral agents that were found in their parents based on specific PCR assays. The incidences of viral infections not vary significantly between male and female broodstock. Our findings demonstrate the persistence of viral infections in shrimp broodstock and their progeny from Sulawesi suggesting the need for screening infectious pathogens to ensure the selection of healthy broodstock, improve biosecurity measures and good practices to produce a domesticated and healthy broodstock, and production of uninfected seed stocks for shrimp cultivation.
