Summary A virus‐adsorption‐elution (viradel) method using electropositive microporous filters (Virosorb 1‐MDS) was used for the concentration and détéction of infectious pancreatic necrosis virus (IPNV) at a hatchery with a past history of IPNV infection. Samples of fish tissue and unconcentrated water were also examined for the presence of IPNV. Virus was isolated from three of the nine concentrated water samples taken from various locations at the hatchery. Virus was also isolated from pooled fish tissues, but not from unconcentrated water samples. Representative numbers of viruses isolated from water and fish tissues were examined for virus neutralization in the presence of anti‐IPNV amiserum; resistance to acid, ether, and heat; and replication in the presence of 5‐bromo‐2'‐deoxyuridine (BUDR). When tested by dot‐immunobinding assay using a panel of monoclonal antibodies (MABs), the viral isolates were found to belong to the West Buxton serotype of IPNV.
