Tassal... or is it Tas-sell? she keeps saying it as if there's an 'e' 
Well.... what I see is that they try to clean up the fish crap, but fail... well... they do everything that is required by law.
They also got a neat deal to use the WWF and ASC logos, apparently.
Apart from that, I see no problem.
Adding chemicals to fish feed that mimic the crustacean nutrients that they'd eat if they were in the wild doesn't shock me... nor "ruminant protein", which is land meat that the fish wouldn't get in the wild.
Personally, I am for fish farming. Done right, it can save many many fish species from over-fishing. Done wrong it'll tank and destroy ecosystems.
The governments should have independent committees that put in place the requirements for such farms, with a dependence on the location... and then monitor them, just as beef and pork producers are now being monitored (at least in the EU, they are).
I eat farmed beef, farmed pork, farmed chicken... I see no problem with farmed fish.
Each of these gets to eat stuff that, on the face of it, seems icky... and, on occasion, I believe that farmers do try to cut as many corners as they can, but... as long as the meat/fish come out healthy (up to death), then I'm ok with eating them.
I sensed that this piece tried to poison the well right at the start showing us the people opposing Tassal's business... And it did seem very real the fact that they are not properly cleaning up their by-products... but everything else just seemed to be scare-mongering an industry that should allow us to save fish wildlife.
