Denmark, for instance, has half its farms as RAS systems - recirculating aquaculture system. Added to the Kenyan system at the bottom (system 73) will bring the current number of on-land farms to 10,000 around the world. Finland never allowed fish farms in its ocean. They all have to be on land.
There is no reason anymore to have old-tech, open-net, in-ocean farms with their environmental degradation problems and open sewage in our pristine oceans. Move forward to the October to December period of 2015 because the Norwegian governement is so angered by in-ocean fish farms that it is awarding free licences for them to set up on land. In ocean licences now go for $9- to $12-million in auction. So the free on-land licences are a significant subsidy as well.
It is time to ask the question: why are fish farms raising Atlantic salmon in BC where there are five species of Pacific salmon? Why are fish farms in the ocean when all their problems can be eliminated on land? Why are fish farms raising carnivores that require the killing of many stocks of ocean fish that should be eaten by people?
Here is a new 2013 document that shows on-land, circulating systems make more money than in-ocean net-pen operations: http://tidescanada.org/wp-content/uploads/files/salmon/workshop-sept-2013/NEWD1-11TrondRostenandBrianVinci.pdf. It is a very technical document, but worth the effort of crunching through it. You will note that different assumptions give different results, but the last page says it all: production of fish on-land is not more expensive than in-ocean (note that this is stated in the negative based on the initial hypothesis statement)
Here is the CAAR symposium link on other closed containment studies: http://tidescanada.org/salmon/aquaculture-innovation-workshops-and-reports/.
Here is the 2010 report written for SOS Marine Conservation Foundation, Technologies for Viable Salmon Aquaculture: http://www.findonnelly.ca/sites/default/files/Technologies_for_Viable_Salmon_Aquaculture.pdf.
SOS concluded that: there is no technical or economic barrier to closed containment salmon farm aquaculture for the production of salmon. Moreover, B.C. is advantageously provisioned for catalyzing an industrial change and for retaining the new emergent industry in B.C.

Here is a link to a closed containment study at the end of 2014, Dec 27: http://fishfarmnews.blogspot.ca/2014/12/study-on-land-fish-farm-systems-make.html.
Here is a link to the Kuterra on-land system in BC. This is a good costing document, and retailers realize the difference and will stock Kuterra salmon, but not Marine Harvest, Cermaq nor Grieg Seafood: See this link: http://www.namgis.bc.ca/ccp/Pages/default.aspx.
Updated, Feb 5, 2015: In Norway each fish farm must pay $1.69 Million to get a licence. [Now, in Dec 2015, there are those free licences to set up on land.]
In BC, because we have very low fees, ($5171.25 X 130 = $67,000), it means we are subsidizing every farm to the tune of $2 million. What this means is that Norwegian-style fish farms have no argument for not being put on land because of cost. They are subsidized now $2 million.
We taxpayers are subsidizing the entire industry of, say, 130 farms (80 operating at any given time) to the tune of $260 million. This is 400% of the entire aquaculture contribution to GPP of $61.9 Million. Fish farms need to be on land, just like the 10,000 other actual on-land farms around the world.
Note that the Norwegian in-ocean licence of $9 to $12 M, means BC is subsidizing fish farms to the tune of $1.17 to $1.56 Billion to use our pristine ocean as a free open sewer.
Updated, May, 2015 The Conservation Fund Freshwater Institute (TCFFI), is producing farmed Atlantics in, get this, Norway. See the article which has a link to the research document: http://www.thefishsite.com/articles/2056/trends-in-salmonid-recirculating-aquaculture-systems/.
There is no need for the dinosaur old-tech in-ocean fish farms any more.
Updated, August 20, 2015, AKVA, listed below in number 26, is having its best year ever selling on-land fish farm systems, even in Norway, for Pete's sake: http://www.undercurrentnews.com/2015/08/20/akva-seeing-historically-high-interest-in-land-based-farming-amid-record-quarter-h1/?utm_source=Undercurrent+News+Alerts&utm_campaign=d35cf2dd4c-Europe_briefing_Aug_20_2015&utm_medium=email&utm_term=0_feb55e2e23-d35cf2dd4c-92426209.
Update to Oct 1, 2015: Fish 2.0, 2015, a competition for sustainable aquaculture projects. See: http://www.fish20.org/news/9-news/217-fish-2-0-new-prizes-7.
Updated, Oct 3, 2015: Here is a good organization of recirculating aquculture systems, in Norway no less: http://www.nordicras.net/Members/Industry. It is the Nordic Network on Recirculating Aquaculture Systems.
Updated, Oct 7, 2015: Here is a Powerpoint presentation on an on-land farm for rainbow trout in Canada. Most importantly, it gives the financial figures on building, production cycle to harvest: http://www.tidescanada.org/wp-content/uploads/2015/03/Dan_Stechey_-_The_Canadian_Model_Farm_Initiative.pdf.
****Updated, Oct 14, 2015. This is a really great summary Powerpoint presentation of a good 30 on-land RAS systems presented in Nanaimo, BC, Canada, 2015, along with financials and metric tonnes: http://www.palomaquaculture.com/support-files/palom-aquaculture-steve-summerfelt-ras-update-june-5-2015.pdf. The question is: how many is enough on-land fish farms before governments pull all in-ocean farms out of the water for their high environmental damage? After all, the only monetary advantage they have is getting off Scot free from their sewage costs, and those are paid for by us, the public, $10.4 Billion in BC alone. We don't want to pay.
Updated, Oct 17, 2015. To identify any BC in-ocean farm, see this DFO link: http://www.pac.dfo-mpo.gc.ca/aquaculture/licence-permis/docs/finfish-pisciculture-eng.html.
Updated, Oct 21, 2015: This is a cost-comparison, by Deloitte, of on-land, in-sea, and on-land and in-sea at different ages. The report says that on-land is the way of the future, because capital costs are lower than in-sea models and operating costs will drop, and growing fish at market site reduces shipping costs. It also sees a market for the three fish farm systems: http://fishfarminginternational.com/tag/land-based/.
