I believe because they received permission to increase production at other sites,
Although I also heard they were moving. So who knows

This tidbit popped out of the snooping around the website - the fight to hide ISAv records from the Commission:

The Cohen commission ran into a lot of roadblocks. The government invoked cabinet privilege to stop Cohen from getting stuff on first nations harvest.

Ok. How about this:
Cohen report: "the large spatial extent of similarities in productivity patterns suggests that mechanisms which operate on larger, regional spatial scales, and/or in places where a large number of correlated sockeye stocks overlap, should be seriously examined. In testimony, Dr. Peterman suggested that these could be things such as predators, pathogens, or oceanographic patterns driven by climate processes."
Cohen Report: "The researchers also found that declines in productivity of Fraser River and other BC stocks have generally coincided with increases in productivity of stocks in western Alaska, most notably Bristol Bay"
Are we sure we shouldn't lay off the salmon farms and get busy with what is happening in Alaska? Wake up you anti-FFarmers. The house is on fire and you are outside watering your tulips.

From your post:
"wild salmon are menaced by an array of other problems beyond aquaculture. Rising sea temperatures, dams impeding their migration, overfishing and hatcheries set up to enhance the harvest in fisheries (yes, using hatcheries to put more salmon in the rivers often results in fewer fish to catch) are all factors that contribute to dwindling numbers of wild salmon worldwide."

They use a weather boy off of pine island to apply an environmental scaler to there return predictor and that's been one of there more accurate ways of calculation returns.
They apparently came up with a new model to calculate returns after the cohen commission but when 2010 happened and returns were sky high that model failed and that's why they use an older model.
The 2010 return of sockeye really shocked everyone that was predicting salmon were on the decline.

But pro salmon ranching.... in Alaska? ....interesting. Overwhelming evidence is clear in what is causing the biggest problem but we continue to denigrate salmon farms which looks like a big nothing burger when it comes to salmon returns.

Most salmon ranching in Alaska happens in Southeastern Alaska-the panhandle. Stocks in western Alaska, most notably Bristol Bay are not enhanced or ranched.

You are probably correct but why is there a correlation between good bristol bay returns and BC poor returns? Is it that Alaska doesn't allow the Bristol Bay salmon to compete with the ranched salmon? The ranched salmon had a record this year as well and they directly compete with our salmon.
From stan
Piscine orthoreovirus (PRV) is the most recently accepted member of the Orthoreovirus genus. It has a pervasive and global distribution in salmon, including both wild and farmed populations, and has been detected in nearly all salmonid species (Garseth et al., 2013; Marty et al., 2015; Olsen et al., 2015; Takano et al., 2016; Morton et al., 2017; Julio et al., 2018).
The virulence of PRV, like most reoviruses, appears to be generally low and highly dependent on virus, host, and/or environmental factors (Garver et al., 2016; Polinski et al., 2019). Nevertheless, PRV1 has been demonstrated as an etiological component of a disease known as heart and skeletal muscle inflammation (HSMI) in farmed Atlantic salmon of Norway (Wessel et al., 2017), which is currently one of the transmissible diseases most affecting Atlantic salmon production in that country1 – the largest Atlantic salmon producer in the world. In Pacific Canada, PRV1 has also been suggested to be involved in a jaundice/anemia syndrome of farmed Chinook salmon (Di Cicco et al., 2018), although its role in this relatively rare disease is far from clear (Garver et al., 2015). In Japan, PRV2 has been associated with an anemic condition of farmed Coho salmon, known as erythrocytic inclusion body syndrome (EIBS) (Takano et al., 2016), while in Europe, PRV3 is associated with an HSMI-like condition in farmed rainbow trout (Olsen et al., 2015). High morbidity has been attributed to both EIBS and HSMI in some farmed populations.
As you can read stan says

Its a rare disease.
i assume by the photo your now talking HSMI, classic topic shift...he shoots.... he scores..... nope goal isn't were it used to be.

Now back to your original comment Cohen report including rule 18 seems complete. It's a rare disease.

Maybe you could provide a reference to what "rare" is and means to you in reference to PRv, Rico?
Because from what I read PRv is nearly ubiquitous in farmed Atlantic salmon.
The condition called "HMSI" where hearts and red blood cells are compromised lasts for a while - but happens along the spectrum of disease caused at least in large part by PRv. In order to know that PRv was the causal mechanism that causes HMSI - one needs to sample along the continuum of that disease progression. That was the basis of the longitudinal study by Di Cicco et al., and can be found at: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0171471

the conclusion to the study above:
- In summary, our longitudinal study identified HSMI over an extended period in 2013–2014 on one farm in BC, Canada, and documented the same correlation between PRV and HSMI lesions in heart tissues as reported for HSMI occurrences in Norway. This is the third country in which PRV has been associated with HSMI lesions, providing supporting evidence that PRV appears to be a component for HSMI development, but falling short of demonstrating that PRV alone is sufficient to cause HSMI. However, it is important to put these data into perspective given what we do not know about the role that PRV has on HSMI in BC salmon. Our data describe the occurrence of HSMI lesions on one of four Atlantic Salmon farms we followed through an entire ocean production cycle. Hence with these data alone, we cannot comment on the spatial extent of this disease or potential impacts on other species, such as wild Pacific salmon. Future epidemiological studies need to be extended both geographically and temporally, to identify the extent of the disease, to further evaluate the relationship with PRV, and to further elucidate predisposing factors that may contribute to the development of HSMI in the field, including environmental and husbandry practices, and strain variation derived through full viral genome sequencing. In addition, challenge studies should be conducted using HSMI positive tissues in both Atlantic and Pacific salmon to assess the disease potential across species and the contribution of PRV (or other identified agents) and additional contributing factors to the development of HSMI lesions.
How about posting the challenge studies recommended in the conclusion above. All of them. Not just the one of your choice.
Lmao..... because the post you referred to says it's rare. You should read stans paper. I didnt say it was rare but stan did........this is what he said and I got this from you.... it's your linkMaybe you could provide a reference to what "rare" is and means to you in reference to PRv, Rico?

I guess this is where I get to type "LMAO" - altho I don't consider the impacts to wild stocks something funny to laugh about even if I am on the BCSFA Christmas card list.
PRv is unfortunately common in farmed ATLANTIC salmon - which is nearly all of the production in farmed salmon - resulting in HSMI in up to 100% of the farm population: Kongtorp RT, Kjerstad A, Taksdal T, Guttvik A, Falk K.

jaundice/anemia syndrome of FARMED Chinook salmon is rare as far as DFO & the industry is concerned. AND FROM THE SAME STUDY: we cannot comment on the spatial extent of this disease or potential impacts on other species, such as wild Pacific salmon.

You failed to include the paragraph after your post. So not much of a conspiracy as you hoped to suggest. Here is more of it. Real scientists identify what they can not comment on. Alexandra Morton...not so much
“we cannot comment on the spatial extent of this disease or potential impacts on otherspecies, such as wild Pacific salmon. Future epidemiological studies need to beextended both geographically andtemporally, to identify the extent of thedisease, to further evaluate the relationshipwith PRV, and to further elucidate predisposing factors that may contribute to the development of HSMI in the field,”
In other words more work is needed. It is currently under way despite your claims nothing is being done.
