A mid-coast BC fish farm fish displaying the symptoms of HSMI. Do you want this in our water, an infected farm releasing 56 billion viral particles per hour? I think not.
The on-land fish farm post remains the most viewed of all my nearing 300 posts on this blog. Here is the most recent iteration of the list: http://fishfarmnews.blogspot.ca/2016/05/152-different-on-land-fish-farm-systems.html.
You will note that the AKVA group has had an 'explosion' of on land sales in Q2, 2016: http://fishfarmnews.blogspot.ca/2016/08/akva-on-land-fish-farm-sales-exploding.html.
Like the two tipping point articles I wrote on the on-land issue in Norway and BC, I think the disease post will come to serve that function well. Disease is a constant in fish farms, around the world, from animals too close to one another and thus spreading disease, some 56 billion viral particles per hour. The Kibenge Powerpoint presentation notes that fish farm disease losses come to be one third to one half of all fish farm fish.
I should have started a disease post long ago, as it, like the bad news bites posts, will become equally as long, and equally damning on the global fish farm industry, that needs to raise a vegetarian fish and do it on land. The Bad News Bites post is here - you might be shocked: http://fishfarmnews.blogspot.ca/2016/07/news-bites-farmed-salmonseafood.html.
You will recall that BC fish farms have had kudoa - MH has had great losses - furunculosis for Grieg Seafood's 'craft' Skuna Bay fish, and Cermaq having an algal bloom in Clayoquot. Then there are the past infections of IHN and IPN. And, you will recall during the Cohen Commission the several different labs that showed ISA in BC, including Are Nyland in Norway, the OIE lab for the eastern hemisphere.
And you will recall from the Cohen Commission, Dr. Kristi Miller's work on the 'viral-signature' wherein she listed the phenotypical disease problems in salmon and what they suggested were the diseases that caused them. This is a novel way of getting at the disease from the problems it causes, rather than the identification of the genetic material of a virus.
Here is the list of diseases, and the issue is that BC is the first place fish farms have come with a huge wild salmon population:

6. HSMI, Furunculosis, Disease, wild herring video, Aug 26, 2016: One GoPro, one stick, one pond on one fish farm, selected randomly. You will come away thinking the odds of such a thing are so small, on a random pick, that all fish farms are this bad: https://www.facebook.com/alexandra.morton.1671/posts/1864901490405070.
5. The HSMI collection fish, 2013 - 2014, not only had HSMI, but the site had an algal bloom, perhaps caused by fish farm sewage, then there was a lice infection, then Slice treatment. See the Powerpoint presentation, page 6: https://www.psf.ca/blog/discovery-hsmi-bc-salmon-farm.
