Well, WMY - as I posted back a few pages on post #158:
Way back on Dec. 05th Dec. 2011 (post #7) - I posted about "my scary scenario" about the unintentional release of of a novel farm disease (ISAv verses PRv which was largely unknown at the time) onto wild stocks and the likely risks and epidemiology at:

Guess what?
In October 17, 2011 ISAv was found in River's Inlet stocks for the 1st time - and there were other years/sampling results afterwards. However, the lab that 1st produced those results (Fred's lab) got it's OIE certification yanked after "Canada" (CFIA & DFO) gave the OIE $2M - because CFIA was protecting trade - rather than wild stocks.
The proper, responsible response would have been to retest - but
*NOT* destroy the samples and deny, deny and deny - and punish Fred - which is what the CFIA actually did. The CFIA NEVER went to River's Inlet to retest the wild salmon population - but these researchers did:

in 2016 - ISAV was reported again:

Charlie, Whole in the Water, GLG substantially added to that 2011 forum conversation - while Charlie even started the thread. Worth a re-read under the context of substituting the focus now on Prv instead of ISAv.
In 2018, PRv was reported found in River's Inlet and also see this blurb on ISAv on page 106 at:

Infectious Salmon Anemia Virus
In sockeye salmon, the overall proportion testing positive for ISAV in 2014 was 1.2% (95% CI: 0.13-5.6%) (Figure B1). In 2015, this proportion was slightly higher at 3.1% (1.2-6.7%) (Figure B2), and in 2016, 0.88% (0.09-4%) tested positive for ISAV (Figure B3). The ISAV positive proportion was driven by sockeye fry in 2014 (3.8%, 0.416.6 %); smolts (3.8%, 1.1-9.7 %) and adults (4.9%, 1.0-14.7 %) in 2015; and smolts (0.88, 0.09-4%) in 2016 (Figures B1-B3).
No trout tested positive for ISAV in 2014 (0, 0-12.8%) (Figure B1) and none were screened for this virus in 2015 or 2016. Likewise, none of the spawning Chinook sampled in 2014 tested positive for ISAV (0, 0-11%; Figure B1), although 5% (0.5421.1%) of spawning Chinook tested positive for ISAV in 2015 (Figure B2). ISAV was not assessed for Chinook in 2016. Wanukv (Rivers Inlet) eulachon were only assessed for ISAV in early 2015 (Figure B2) and 7.4% returned positive results (95% CI: 1.6-21.7%). Klinaklini River eulachon showed a 5.3% positive rate for ISAV (95% CI 0.6-22%) (not shown).
Co-incidentally - as well as sockeye - Eulachon have also been depressed in River's Inlet and most of the Central Coast for some years...
