I also thought it was a nice documentary. I caught about 2/3 of the program tonight and am not really surprised by what I heard.

The featured biologists outlined some pretty compelling, hard evidence that these netpens are rapidly degrading the surrounding environment and fish populations. Did you see the sludge underneath the pens on the seafloor? It's sickening. The fact that the operators move their pens now and then because their own frming has degraded the area to the point where they don't even want to be there says alot.
The sealice component of the show was pretty shocking... smolts with a half dozen lice and larvae just becasue they swam in close proximity to the pens.

All this coupled with the impact to shellfish, & Atlantic Salmon out-competeing indigenous wild fish for food and habitat, etc etc. I hope the Canadian and U.S. governments step up and begin performing some major studies on the farming impacts, which would definatley be a required pre-requisite to any reform. Get those studies started now if they are not already underway.
