In-ocean fish farms are old-tech dinosaurs and should be legislated out of the water to save the pristine environments, and wild fish stocks. It is so simple.
Go to this link to visit all the on-land fish farm systems I have found: http://fishfarmnews.blogspot.ca/2012/01/key-document-34-mostly-on-land-closed.html. If you have trouble, just go to the posts for January 2012 and you will find it.
Here are the new sites. Six links, but actually sixteen more on-land fish farms:
1. Tilapia, MDM Aqua Farms, Rumsey, Alberta, Canada, http://www.mdmaqua.ca/, website unavailable, 04/19/2013
2. Halibut, Scotia Halibut (Nova Scotia), http://www.halibut.ns.ca, landbased, Wood’s Harbour, Clark’s Harbour.
