This creates severely "de-nutrinized" food, so much that it one might argue this kind of food is junk. Many fishes are fed with grains, this destroys their nutritional value, which begs the question if it even makes sense to eat fish who are fed with food they wouldn't eat at all in a natural environment.

This may be the case now, but it's not intrinsic to 'farmed fish'. We can craft nutritious, similar-to-natural, or even better, fish foods. If the incentives are correctly aligned.

    you are right but "citation needed" isn't a polite way of responding to a comment. This isn't a wikipedia editing battle.

  Be wary of intrinsic thinking. Something may not be intrinsic, but still be the expected result. In principle, wild harvests are not intrinsically harmful to the environment. In practice, all commercial fisheries are to various degrees. Large scale aquaculture has a ton of issues. Disease, nutrition, pollution. Not intrinsic, but practically. That said, I do think we can attain a decent quality of aquaculture. The best commercial approach is currently freshwater fish grown in isolation from natural water sources with waste water used for irrigation. Tilapia, basically. Problem is, people want salmon, cod, tuna, oysters... Salmon is farmed at scale. We know the result. Very high parasite loads. Visibly reduced health of the fish. Nutritional issues. We could easily farm a different species, that naturally thrives in environments similar to those we can recreate agriculturally... the demand is for salmon.

  No citation needed, google how grain fed animals have an increase omega 6 which causes inflammation. You cannot expect animals fed with corn to have the same nutrition value than an animal which feeds on diverse food in real life. Read on NN Taleb, you don't understand complex systems.
