Rainbow trout is a low mercury fish and very nutritious.Not to be confused with the sea trout or salmon trout,steelhead in the states they are different beasts.All the fish you see on a fishmongers slab in Europe that's called salmon trout (a prized game fish that is actually a trout that's gone out to sea for it's holiday) is farmed rainbow trout.Mind you trout was one of the earliest farmed fish so they have probably been interbred to form all sorts of mutations.
I caught a trout in the river Thames,while spinning for pike of Monkey Island near Bray early 70s.I was told it probably came from a fish farm that flooded some years earlier.That was inedible.
Whataboutism. Is that your standard MO? When someone provides indisputable facts to an argument, you wholesale disregard and slander the points of ones arguments as “opinion pieces” Surely those who write so called opinion pieces also rely on data
