abstract
In tiger grouper Epinephelus fuscoguttatus production, disease outbreaks caused by systemic viral infection are being increasingly reported as an important limiting factor for the production sustainability. The infection of viral disease leads to great economic loss and become a significant challenge to the expansion of tiger grouper production. Here we demonstrated that conditioning tiger grouper with combination of medicinal plant extracts enhanced the survival in comparison to non-treated group. However, the virus was still detected in clinically normal tiger grouper 8 days after experimental inoculation and herbal bio conditioning treatment, indicating that some may be asymptomatic carriers within the aquaculture system. These results indicated that the administration of herbal extracts derived from combination of herbal biomedicines plants generate protective immunity in the tiger grouper against iridovirus infection.
