Lots of reading for all.......if one decides to actually read it which Morton either didn't or can't help but throw in her own false narrative.
Could the piscine reovirus be harmful in one ocean, and harmless in another as was commonly believed? The answer is no. - Alexandra Morton
The authors stated: "Our farm level study was not designed to investigate causal relationships between any agent and histopathological lesions." (Pg. 24)
The authors also reiterated, to date, that no causal relationship between PRV and HSMI has been established. (Pg. 23)
The paper reports that piscine reovirus infects the red blood cells of fish, where it lies in wait for the fish to experience some kind of stress, such as sea lice, handling, disease, warm water etc. at which point it is released and damages the salmon's heart and the muscles the run the length of the fish that are required to swim. This means that every time farm salmon are deloused, the stress of that can cause an outbreak where billions of viral particles will explode into the surrounding waters. What does this mean for wild salmon? Double jeopardy - lice then infection. - Alexandra Morton
Another twists of the facts by Morton. The authors never reported this. I challenge farm critics to find anywhere in the report where it is demonstrated that PRV "lies in wait", then following stress is "released and does the damage Morton claims. Again, the authors never designed their study to find a causal relationship so how can Morton conclude this? It's my opinion that Morton took a section of pg 24 and either misinterpreted it or does what she normally does which is to twist it so it fits her narrative. The authors were saying "If PRV were to have a role in the development of HSMI" - not that they concluded that it did. She probably believes in the Bowling Green Massacre also. She totally exaggerates the movement of viral particles as some explosive event yet no causal relationship between PRV or HSMI has been established.
What the study does point towards is that stressful events tend coincide with the development of HSMI, but not we know that PRV causes HSMI and this is how it does it.
There is a lot of other things the authors say which Morton doesn't mention.
