1. They escape and introduce disease into wild salmon populations.
2. The sheer amount of feces and uneaten food that falls through the containment nets, combined with all sorts of microorganisms create massive dead zones beneath them.
3. Farm raised salmon are fed a ground fish meal made of baitfish species that are known to accumulate toxins, not because that's what a salmon would normally eat, but because they're easier for humans to harvest. This results in farm raised salmon having much higher concentrations of lead, PCBs, mercury, etc.
4. The containment nets catch, strangle, and kill marine life such as seals, seabirds, and dolphins.
Wild caught salmon isn't a problem. It is harvested sustainably, contains less contaminants, and is often less expensive.
If you have any more questions regarding which types of fish should be avoided, the Monterey Bay Aquarium maintains an excellent online resource.

It takes like 4 kilos of fish to make 1 kilo of salmon. What a waste!
