When we walked along the eastern shore the other day we took photographs of the salmon farm that's now located off McNutt's Island in the eastern channel of Shelburne Harbour. You can see the former military base at Government Point in the background -- that's where the outer harbour ends and the Atlantic begins.
I could only count nine cages but I've been told there are thirteen in this location. Maybe some are attached behind others.
Nobody really knows what effect salmon farming will have on the harbour. There are many other already-established aquaculture sites and proposed sites within Shelburne's inner harbour. These are the only cages in the outer harbour as of now.
As you can imagine, it's controversial. If you want to know more about it, here's a link: Friends of Shelburne Harbour.
