Objective: To determine whether or not aquabirnavirus is present in Victorian fish hatcheries.
Procedure: Milt and ovarian fluids were collected from brood stock at 12 hatcheries and cultured in two sensitive cell lines for the presence of viruses.
Results: No cytopathic effect was detected indicating the absence of virus.
Conclusion: There is no evidence of infection with aquabirnavirus or Epizootic Haematopoietic Necrosis virus in Victorian fish hatcheries.
