Abstract
The incidence of yellowtail ascites virus (YAV) was examined in wild yellowtail Seriola quinque-radiata fingerlings collected at 10 different stations along the coast of Tosa Bay in 1986. The incidence of YAV in fingerlings was 14.9% examined on CHSE-214, RTG-2, EK-1, and YTG cells, 14.5% on BF-2 cells and 8.57% on FHM cells, respectively. 47.1% of the carrier fingerlings developed ascites and their mean virus titer was 106.0 TCID50/g. On the other hand, the mean virus titer of the carrier fingerlings which did not exhibit ascites was 103.6 TCID50/g. The incidence of YAV in fingerlings varied by sampling periods. There was a tendency of negative correlation between the incidence of the virus and the body weight of the fingerling. These results suggest that the YAV was carried into the fish farms from offshore with the fingerlings used for the pen culture.
