Of course, in terms of the ocean floor, my understanding is that these net pens are moved on a fairly regular basis. From a study that we did those few years ago, I recall that I asked specifically about the ocean floor and the recovery time was about three years for the ocean floor. The effect of a net pen on the ocean floor is clearly temporary, just like a clear cut is a temporary event in a forest.
Given the state of wild fish stocks around the world, especially high seas ocean fish stocks that are in deep trouble, can we make the conclusion that every farmed fish that is sold is one less wild salmon that needs to be caught?
