Used to work in Fish Health. Very familiar with virus as we had a few nice blow-ups to deal with.
The AS were carrying the virus. Just like we all carry E. coli. All that means is that the bug was in the fish.
The AS were not "diseased", at least not caused by the virus. It was just there.
The virus has not yet been found in wild Pacifics, except that maybe the rare individual.
The virus has not, to my knowledge, been shown to cause actual disease in Pacifics.
This last is important. Back in the late 80s we had some isolations of the VHS virus. Known to be very lethal to Pacifics and believed (note closely that word) to have been carried in by cultured Atlantics. The VHSV that AS normally had, in the Atlantic, was really bad for Pacifics. So, we went about killing whole hatcheries, disinfecting them, and so on. But, we also continued to look at the bugs. Turns out, the VHSV here was native, was found primarily in cod and herring, and was fairly benign to Pacifics. Didn't stop the anti-AS crowd, even after the information was published in peer-reviewed journals.
My point is that words used in the statements have to be looked at very closely for their specific definitions. And, we need to find out just what the bug can actually do to local fish.
