Farmed salmon escape in Canada
Last month, 138,000 farmed salmon escaped from feedlots on the New Brunswick side of the Bay of Fundy, a fact that scarcely caused a ripple in the Maritime consciousness reports Donald Cameron of Canada's Chronicle Herald.
Elsewhere — in Norway, Scotland, Chile, British Columbia — salmon farming is a highly controversial industry. Here it seems to skate along smoothly under the radar.
Salmon farming is controversial for two main reasons. First, it is a highly inefficient way to produce food. Producing feed for farmed salmon intensifies the pressure on other fisheries around the world. In effect, the process turns four kilograms of wild fish into one kilogram of industrial fish. How clever is that?
"The clustered fish are succulent targets for epidemics of parasites such as sea lice, which can move easily through the mesh cages, and viruses such as infectious salmon anemia, which first appeared in Norway in the 1980s, and now inhabits salmon farms in Scotland, Chile and New Brunswick."
