Farmed seafood is among the worst garbage you can eat. Tons of antibiotics, growth hormones, fish are fed utter cheap junk so ie salmon meat has more like pork composition than a wild salmon, shrimp are even worse. If you ever saw a shrimp 'factory' and grow pond/cage and its surroundings in a typical 3rd world country where most come from, you wouldn't eat it for a long time if ever again. Literally nothing lives around those places.
That take’s outdated. In the US/EU, routine antibiotics in fish farming are banned [1]. Growth hormones aren’t used in edible fish. Farmed salmon’s feed changed (more plant oils), but it still delivers high omega-3s and usually less mercury than wild [2].
OK thats a good development. But overall difference in quality of meat is even visible - farmed salmon looks like a completely different fish than wild one (if you even can get one) - akin to difference between say boar and domesticated pig (lean muscle vs tons of fatty wobbly tissue). It doesn't scream 'healthy' but that may be just emotions playing old tune.
Also what I wrote about shrimp from any 3rd world country is valid - I've seen such place this summer in Indonesia, and from what I've heard whole south east Asia is exactly like that, or worse. Getting shrimp from some western democracy with strong consumer protection rights ain't possible in many parts of Europe, not sure about other places
Good in theory, horrible in practice.
