As a Norwegian, I can tell you farmed fish is not as ecologically friendly as one might believe. Here it's generally farmed in fjords. Because factory farming and parasites go hand in hand, parasites are a huge problem, killings lots of fish. To combat this, they dump a bunch of nasty chemicals into the water like organophosphates and ivermectin. This is very harmful to aquatic life in the area. The parasites bred in these conditions can also be dangerous to aquatic ecosystems. And farmed salmon have a tendency to escape their ponds and mess up wild fish populations.
May be less ecologically harmful than fishing, but it's not exactly good either.
Edit: correction as per the helpful reply below.
- belval 3y agoNot to counter your comment as I agree, but: > nasty chemicals into the water like hydrogen peroxide Hydrogen peroxide really isn't that problematic. It is pretty unstable and reacts into oxygen and water. It kills algae and bacteria in what is likely the cleanest way possible.
- mtlmtlmtlmtl 3y agoFair enough. That was just the one I remembered off the top of my head. Always happy to be corrected! But they're using all sorts of different stuff. It's been so bad at times they've basically been throwing spaghetti at a wall to see if it sticks. Most of it there's not even any research to suggest the drugs they're trying are safe ecologically. But they try it anyway; it's a woefully underregulated industry right now. And there's the general problem that any indiscriminate use of antibiotics(in the general definition of the word, not the one restricted to bacteria) in a factory farming context is bound to lead to the development of highly resistant pathogens. That just follows from Darwin, really.
