It is worth reading because it gives a very thorough overview of land-based fish farming. The Namgis First Nation on Vancouver Island have successfully grown farmed Atlantic salmon on land, and because of its positive environmental footprint Sobey's/Safeway Canada will buy their product, while they will not buy in-ocean net-pen salmon produced by Marine Harvest, Cermaq an Grieg-seafood because of its overwhelmingly negative environmental damage.
Marine Harvest, Cermaq and Grieg Seafood are old-tech dinosaurs that use our oceans as free, open sewers for their sewage and diseases. On-land, recirculating systems - my list now has 122 different ones, comprising more than 10,000 farms around the world - are the way of the future. The Norwegians, by refusing to change, are simply destroying their own businesses. That includes their farms in BC, and their very few jobs.
