The same problems that happen in one country willing to ruin its ocean to allow fish farms, claims another victim. Tasmania. This is something I predicted in a post two years ago, and had an ongoing exchange with a journalist from Tasmania. The solution is to take them out of the ocean and put them on land, as it always has been the solution.
Look back to the index: http://fishfarmnews.blogspot.ca/2016/01/key-document-index-2015.html.
In the index, you will see a link to the previous index: http://fishfarmnews.blogspot.ca/2014/10/index-to-wwwfishfarmnewsblogspotcom.html.
Too many fish in too small a space, the same unchecked growth in a pristine wilderness water, in this case, right next to a world heritage wilderness area, just like in BC's Clayoquot Sound.
Much global news in the more than 20 fish farm newsletters I receive each week has been devoted to the issue, claims and counterclaims. See my Bad News Bites post: http://fishfarmnews.blogspot.ca/2016/07/news-bites-farmed-salmonseafood.html.
Look at items 241, 246 and 247.
Here is another one: http://www.abc.net.au/news/2016-10-31/salmon-farmer-says-tas-government-ignored-overstocking-warning/7978770. Frances Bender of Huon Aquaculture tells the problem, and though a salmon farmer, she has briefed the government several times in the last year, as she thinks a disaster is about to happen - low oxygen, temperature spikes and so on, and then a disaster of fish deaths. They have been lowering their salmon numbers.
Do note that she went from adding a few salmon to supplement their sheep and cattle business, and now Huon is an ASX-listed company with $230 million in revenue.
This is a good example of the Boom/Bust nature of salmon farming. There is so much money to be made that plans go wild, and several years later the entire industry collapses. Placentia Bay and Grieg Seafood in NL is a good example of one now in the Boom phase.
And it was only in March 2016 that Chile went through a huge collapse with 23 million farmed salmon dying from an algal bloom caused, in part by fish farm sewage, and dumping 75,000 metric tonnes of dead salmon only 50 miles offshore.
Earlier this year in BC, Cermaq lost lots of salmon in Clayoquot sound BC, to, an algal bloom, while just north in Nootka Sound, Grieg Seafood's 'craft raised' Skuna farmed salmon were dying of furunculosis. Then there are the ongoing serious problems in Scotland with AGD disease.
And the Morton Gopro video showed a randomly chosen farm, random pen with emaciated, obviously sick salmon. And we know that 80% of BC farmed salmon have PRV because the provincial health unit, GD Marty and Co., have the proof. Not to mention that I published it on Fish Farm News: http://fishfarmnews.blogspot.ca/2016/10/prv-present-in-80.html.
Do read the Tasmanian news article, and that fish farms are bad news all over the world. They need to be on land.
